Acid Reflux Disease or gastric reflex disease (GERD) Heartburn in simple words “Heartburn”, is a condition in which the liquid content of the stomach regurgitates (backs up or refluxes) into the esophagus, often causing heartburn.

The liquid can inflame and damage the lining (esophagitis) although visible signs of inflammation occur in a minority of patients. The regurgitated liquid usually contains Hydrochloric acid and pepsin that are produced by the stomach (pepsin is an enzyme that begins the digestion of proteins in the stomach). The refluxed liquid also may contain bile that has backed up into the stomach from the duodenum. Hydrochloric Acid is believed to be the most injurious component of the refluxed liquid. Pepsin and bile also may injure the esophagus, but their role is not as clear as the role of Hydrochloric acid.

Acid Reflux Disease (GERD) is a chronic condition, under allopathic treatment, it usually is life-long. If there is an injury to the lining of the esophagus (esophagitis), this also is a chronic condition. Moreover, after the esophagus has healed with allopathic treatment and treatment is stopped, the injury will return in most patients within a few months, while after Homeopathic treatment it’s all symptoms and causes disappear for many years.

Once treatment for GERD is begun it will need to be continued indefinitely. However, some patients with intermittent symptoms and no esophagitis can be treated only during asymptomatic periods.

In fact, reflux of the stomach’s liquid contents into the esophagus occurs in most normal individuals. Sometime reflux occurs frequently in normal individuals as in patients with GERD. In patients with Acid Reflux Disease (GERD), however, the refluxed liquid contains acid more often, and the acid remains in the esophagus longer. It has also been found that liquid refluxes to a higher level in the esophagus in patients with GERD than in normal individuals.

As is often the case, the body has ways to protect itself from the harmful effects of reflux and acid:

  • For example, most reflux occurs during the day when individuals are upright. In the upright position, the refluxed liquid is more likely to flow back down into the stomach due to the effect of gravity.
  • In addition, while individuals are awake, they repeatedly swallow, whether or not there is reflux. Each swallow carries any refluxed liquid back into the stomach. Finally, the salivary glands in the mouth produce saliva, which contains bicarbonate. With each swallow, bicarbonate-containing saliva travels down the esophagus. The bicarbonate neutralizes the small amount of acid that remains in the esophagus after gravity and swallowing has removed most of the acidic liquid.
  • Gravity, swallowing, and saliva are important protective mechanisms for the esophagus, but they are effective only when individuals are in an upright position. At night during sleep, gravity has no effect, swallowing stops, and the secretion of saliva is reduced. Therefore, reflux that occurs at night is more likely to result in acid remaining in the esophagus longer and causing greater damage to the esophagus.

Certain conditions make a person susceptible to GERD. For example, GERD can be a serious problem during pregnancy. The elevated hormone levels of pregnancy probably cause reflux by lowering the pressure in the lower esophageal sphincter (see below). At the same time, the growing fetus increases the pressure in the abdomen. Both of these effects would be expected to increase reflux. Also, patients with diseases that weaken the esophageal muscles, such as scleroderma or mixed connective tissue diseases, are more prone to develop GERD.

Causes of Acid Reflux Disease (GERD) are complex and may involve multiple factors. Acid Reflux Disease (GERD) may damage the lining of the esophagus, thereby causing inflammation (esophagitis), although this is uncommon.

Symptoms of uncomplicated acid reflux disease or gastric reflex disease include:

Complications of Acid Reflux Disease (GERD) include:

    • ulcers and strictures of the esophagus,
    • Barrett’s esophagus,
    • cough and asthma,
    • throat and laryngeal inflammation,
    • inflammation and infection of the lungs, and
    • a collection of fluid in the sinuses and middle ear.

Acid Reflux Disease (GERD) may be diagnosed or evaluated by a variety of procedures and tests.

Acid Reflux Disease (GERD) is treated with lifestyle changes, diet, over the counter (OTC) and prescription drugs {for example, antacids, proton pump inhibitors (PPIs), promotility drugs}, and surgery.

Causes of Acid Reflux Disease (GERD)

The cause of Acid Reflux Disease (GERD) is complex and may involve multiple factors. Different causes may affect different individuals or even in the same individual at different times. A small number of patients with Acid Reflux Disease (GERD) produce abnormally large amounts of acid.

The factors that contribute to Acid Reflux Disease (GERD) are:

  • lower esophageal sphincter abnormalities,
  • hiatal hernias,
  • abnormal esophageal contractions, and
  • slow or prolonged emptying of the stomach.

Lower esophageal sphincter

The action of the lower esophageal sphincter (LES) is the most important factor (a mechanism) for preventing reflux.

The esophagus is a muscular tube that extends from the lower throat to the stomach. The LES is a specialized ring of muscle that surrounds the lowermost end of the esophagus where it joins the stomach. The muscle that makes up the LES is active most of the time, that is, at rest. This means that it is contracting and closing off the passage from the esophagus into the stomach. This closing of the passage prevents reflux. When food or saliva is swallowed, the LES relaxes for a few seconds to allow the food or saliva to pass from the esophagus into the stomach, and then it closes again.

Several different abnormalities of the LES have been found in patients with GERD. Two of them involve the function of the LES:

  1. The first is an abnormally weak contraction of the LES, which reduces its ability to prevent reflux.
  2. The second is abnormal relaxations of the LES, called transient LES relaxations.

They are abnormal in that they do not accompany swallows and they last for a long time, up to several minutes. These prolonged relaxations allow reflux to occur more easily. The transient LES relaxations occur in patients with GERD most commonly after meals when the stomach is distended with food. Transient LES relaxations also occur in individuals without GERD, but they are infrequent.

The most recently described abnormality in patients with GERD is the laxity of the LES. Specifically, similar distending pressures open the LES more in patients with GERD than in individuals without GERD. At least theoretically, this would allow for the easier opening of the LES and/or greater backward flow of acid into the esophagus when the LES is open.

Hiatal hernia

Hiatal hernias contribute to reflux, although the way in which they contribute is not clear. A majority of patients with GERD have hiatal hernias, it is not necessary to have a hiatal hernia in order to have GERD. Moreover, many people have hiatal hernias but do not have GERD. It is not known for certain how or why hiatal hernias develop.

Normally, the LES is located at the same level where the esophagus passes from the chest through a small opening in the diaphragm and into the abdomen. (The diaphragm is a muscular, horizontal partition that separates the chest from the abdomen.) When there is a hiatal hernia, a small part of the upper stomach that attaches to the esophagus pushes up through the diaphragm. As a result, a small part of the stomach and the LES come to lie in the chest, and the LES is no longer at the level of the diaphragm.

It appears that the diaphragm that surrounds the LES is important in preventing reflux. That is, in individuals without hiatal hernias, the diaphragm surrounding the esophagus is continuously contracted, but then relaxes with swallows, just like the LES. Note that the effects of the LES and diaphragm occur at the same location in patients without hiatal hernias. Therefore, the barrier to reflux is equal to the sum of the pressures generated by the LES and the diaphragm.

When the LES moves into the chest with a hiatal hernia, the diaphragm and the LES continue to exert their pressures and barrier effect. However, they now do so at different locations. Consequently, the pressures are no longer additive. Instead, a single, high-pressure barrier to reflux is replaced by two barriers of lower pressure, and reflux thus occurs more easily. So, decreasing the pressure barrier is one way that a hiatal hernia can contribute to reflux.

Esophageal contractions

As previously mentioned, swallows are important in eliminating acid in the esophagus. Swallowing causes a ring-like wave of contraction of the esophageal muscles, which narrows the lumen (inner cavity) of the esophagus. The contraction, referred to as peristalsis, begins in the upper esophagus and travels to the lower esophagus. It pushes food, saliva, and whatever else is in the esophagus into the stomach.

When the wave of contraction is defective, refluxed acid is not pushed back into the stomach. In patients with GERD, several abnormalities of contraction have been described. For example, waves of contraction may not begin after each swallow, or the waves of contraction may die out before they reach the stomach. Also, the pressure generated by the contractions may be too weak to push the acid back into the stomach.

Such abnormalities of contraction, which reduce the clearance of acid from the esophagus, are found frequently in patients with GERD. In fact, they are found most frequently in those patients with the most severe GERD. The effects of abnormal esophageal contractions would be expected to be worse at night when gravity is not helping to return refluxed acid to the stomach. Note that smoking also substantially reduces the clearance of acid from the esophagus. This effect continues for at least 6 hours after the last cigarette.

Emptying of the stomach

Most reflux during the day occurs after meals. This reflux probably is due to transient LES relaxations that are caused by distention of the stomach with food. A minority of patients with GERD, about, has been found to have stomachs that empty abnormally slowly after a meal. This is called gastroparesis. The slower emptying of the stomach prolongs the distention of the stomach with food after meals. Therefore, slower emptying prolongs the period of time during which reflux is more likely to occur. There are several allopathic drugs associated with impaired gastric emptying, such as:

  • narcotics,
  • tricyclic antidepressants,
  • calcium channel blockers (CCBs),
  • clonidine,
  • dopamine agonists,
  • lithium nicotine and progesterone.
  • Steroids
  • non-steroidal anti-inflammatory drugs.

Symptoms of complicated Acid Reflux Disease (GERD)

Symptoms of complicated GERD are primarily:

  • heartburn (sometimes interpreted as chest pain).
  • regurgitation.
  • nausea.
  • Foul odor from mouth
  • Mouth ulcers.

Heartburn in Acid Reflux disease

When acid refluxes back into the esophagus in patients with GERD, nerve fibers in the esophagus are stimulated. This nerve stimulation results most commonly in heartburn, the pain that is characteristic of GERD. Heartburn usually is described as a burning pain in the middle of the chest. It may start high in the abdomen or may extend up into the neck. In some patients, however, the pain may be sharp or pressure-like, rather than burning. Such pain can mimic heart pain (angina). In other patients, the pain may extend to the back.

Since acid reflux is more common after meals, heartburn is more common after meals. Heartburn is also more common when individuals lie down because, without the effects of gravity, reflux occurs more easily, and acid is returned to the stomach more slowly. Many patients with GERD are awakened from sleep by heartburn.

Episodes of heartburn tend to happen periodically. This means that the episodes are more frequent or severe for a period of several weeks or months, and then become less frequent or severe or even absent for several weeks or months. This periodicity of symptoms provides the rationale for intermittent treatment in patients with GERD who do not have esophagitis. It’s not true that, heartburn is a lifelong problem, and it almost always returns.

Regurgitation in Acid Reflux disease

Regurgitation is the appearance of refluxed liquid in the mouth. In most patients with GERD, typically only small quantities of liquid reach the esophagus, and the liquid remains in the lower esophagus. Occasionally in some patients with GERD, larger quantities of liquid, sometimes containing food, are refluxed and reach the upper esophagus.

At the upper end of the esophagus is the upper esophageal sphincter (UES). The UES is a circular ring of muscle that is very similar in its actions to the LES. That is, the UES prevents esophageal contents from backing up into the throat. When small amounts of refluxed liquid and/or foods get past the UES and enter the throat, there may be an acid taste in the mouth. If larger quantities breach the UES, patients may suddenly find their mouths filled with liquid or food. What’s more, frequent or prolonged regurgitation can lead to acid-induced erosions of the teeth, mouth ulcers etc.

Nausea

Nausea is uncommon in GERD. In some patients, however, it may be frequent or severe and may result in vomiting. In fact, in patients with unexplained nausea and/or vomiting, GERD is one of the first conditions to be considered. It is not clear why some patients with GERD develop mainly heartburn and others develop mainly nausea.

Complications of Acid Reflux Disease (GERD)

Ulcers

The liquid from the stomach that refluxes into the esophagus damage the cells lining the esophagus. The body responds in the way of inflammation (esophagitis). The purpose of inflammation is to neutralize the damaging agent and begin the process of healing.

If the damage goes deeply into the esophagus, an ulcer form. An ulcer is simply a break in the lining of the esophagus that occurs in an area of inflammation. Ulcers and the additional inflammation they provoke may erode into the esophageal blood vessels and give rise to bleeding into the esophagus.

Strictures

Ulcers of the esophagus heal with the formation of scars (fibrosis). Over time, the scar tissue shrinks and narrows the lumen (inner cavity) of the esophagus. This scarred narrowing is called a stricture.

Swallowed food may get stuck in the esophagus once the narrowing becomes severe enough (usually when it restricts the esophageal lumen to a diameter of one centimeter). This situation may necessitate endoscopic removal of the stuck food. Then, to prevent food from sticking, the narrowing must be stretched (widened). Moreover, to prevent a recurrence of the stricture, reflux also must be prevented.

Barrett’s esophagus

Long-standing and/or severe GERD causes changes in the cells that line the esophagus in some patients. These cells are pre-cancerous and may, though usually, become cancerous. This condition is referred to as Barrett’s esophagus and occurs in approximately 10% of patients with GERD. The type of esophageal cancer associated with Barrett’s esophagus (adenocarcinoma) is increasing in frequency. It is not clear why some patients with GERD develop Barrett’s esophagus, but most do not.

Barrett’s esophagus can be recognized visually at the time of an endoscopy and confirmed by microscopic examination of the lining cells. Then, patients with Barrett’s esophagus can undergo periodic surveillance endoscopies with biopsies although there is no agreement as to which patients require surveillance. The purpose of surveillance is to detect progression from pre-cancer to more cancerous changes so that cancer-preventing treatment can be started.

It also is believed that patients with Barrett’s esophagus should receive maximum treatment for GERD to prevent further damage to the esophagus. Procedures are being studied that remove the abnormal lining cells. Several endoscopic and non-surgical techniques can be used to remove the cells. These techniques are attractive because they do not require surgery; however, there are associated with complications, and the long-term effectiveness of the treatments has not yet been determined.

Cough and asthma

Many nerves are in the lower esophagus. Some of these nerves are stimulated by refluxed acid, and this stimulation results in pain (usually heartburn). Other nerves that are stimulated do not produce pain. Instead, they stimulate yet other nerves that provoke coughing. In this way, refluxed liquid can cause coughing without ever reaching the throat! In a similar manner, reflux into the lower esophagus can stimulate esophageal nerves that connect to and can stimulate nerves going to the lungs. These nerves to the lungs then can cause the smaller breathing tubes to narrow, resulting in an attack of asthma.

Although GERD may cause cough, it is not a common cause of unexplained coughing. Although GERD also may be a cause of asthma, it is more likely that it precipitates asthmatic attacks in patients who already have asthma. Although chronic cough and asthma are common ailments, it is not clear just how often they are aggravated or caused by GERD.

Inflammation of the throat and larynx

If refluxed liquid gets past the upper esophageal sphincter, it can enter the throat (pharynx) and even the voice box (larynx). The resulting inflammation can lead to a sore throat and hoarseness. As with coughing and asthma, it is not clear just how commonly GERD is responsible for otherwise unexplained inflammation of the throat and larynx.

Inflammation and infection of the lungs

The refluxed liquid that passes from the throat (pharynx) and into the larynx can enter the lungs (aspiration). The reflux of liquid into the lungs (called aspiration) often results in coughing and choking. Aspiration, however, also can occur without producing these symptoms. With or without these symptoms, aspiration may lead to infection of the lungs and result in pneumonia.

This type of pneumonia is a serious problem requiring immediate treatment. When aspiration is unaccompanied by symptoms, it can result in slow, progressive scarring of the lungs (pulmonary fibrosis) that can be seen on chest X-rays. Aspiration is more likely to occur at night because that is when the processes (mechanisms) that protect against reflux are not active and the coughing reflex that protects the lungs also is not active.

Fluid in the sinuses and middle ears

The throat communicates with the nasal passages. In small children, two patches of lymph tissue, called the adenoids, are located where the upper part of the throat joins the nasal passages. The passages from the sinuses and the tubes from the middle ears (Eustachian tubes) open into the rear of the nasal passages near the adenoids. The refluxed liquid that enters the upper throat can inflame the adenoids and cause them to swell. The swollen adenoids then can block the passages from the sinuses and the Eustachian tubes.

When the sinuses and middle ears are closed off from the nasal passages by the swelling of the adenoids, fluid accumulates within them. This accumulation of fluid can lead to discomfort in the sinuses and ears. Since the adenoids are prominent in young children, and not in adults, this fluid accumulation in the ears and sinuses is seen in children and not adults.

Diagnosis and evaluation of Acid Reflux Disease (GERD)

There are a variety of procedures, tests, and evaluation of symptoms (for example, heartburn) to diagnose and evaluate patients with GERD.

Symptoms and response to treatment (therapeutic trial)

GERD is typically diagnosed by its characteristic symptom, heartburn. Heartburn is most frequently described as a sub-sternal (under the middle of the chest) burning that occurs after meals and often worsens when lying down. To confirm the diagnosis, physicians often treat patients with medications to suppress the production of acid by the stomach. If the heartburn then is diminished to a large extent, the diagnosis of GERD is considered confirmed. This approach of making a diagnosis on the basis of a response to treatment is commonly called a therapeutic trial.

There are problems with this approach. For instance, patients who have conditions that can mimic GERD, specifically duodenal or gastric (stomach) ulcers, also can actually respond to such treatment. In this situation, if the physician assumes that the problem is GERD, the cause of the ulcer disease would be missed such as a type of infection called Helicobacter pylori (H. pylori), or nonsteroidal anti-inflammatory drugs or NSAIDS (for example, ibuprofen, aspirin, diclofenac etc), can also cause ulcers and these conditions would be treated differently from GERD.

Upper gastrointestinal endoscopy (also known as esophago-gastro-duodenoscopy or EGD) is a common way of diagnosing GERD. EGD is a procedure in which a tube containing an optical system for visualization is swallowed. As the tube progresses down the gastrointestinal tract, the lining of the esophagus, stomach, and duodenum can be examined.

The esophagus of most patients with symptoms of reflux looks normal. Therefore, in most patients, endoscopy will not help in the diagnosis of GERD. However, sometimes the lining of the esophagus appears inflamed (esophagitis). Moreover, if erosions (superficial breaks in the esophageal lining) or ulcers (deeper breaks in the lining) are seen, a diagnosis of GERD can be made confidently. Endoscopy will also identify several of the complications of GERD, specifically, ulcers, strictures, and Barrett’s esophagus. Biopsies also may be obtained.

Finally, other common problems that may be causing GERD-like symptoms can be diagnosed (for example ulcers, inflammation, or cancers of the stomach or duodenum) with EGD.

Biopsies

Biopsies of the esophagus that are obtained through the endoscope are not considered very useful for diagnosing GERD. They are useful, however, in diagnosing cancers or causes of esophageal inflammation other than acid reflux, particularly infections. Moreover, biopsies are the only means of diagnosing the cellular changes in Barrett’s esophagus. More recently, it has been suggested that even in patients with GERD whose esophagi appear normal to the eye, biopsies will show a widening of the spaces between the lining cells, possibly an indication of damage. It is too early to conclude, however, that seeing widening is specific enough to be confident that GERD is present.

X-rays

Before the introduction of endoscopy, an X-ray of the esophagus (called an esophagram) was the only means of diagnosing GERD. Patients swallowed barium (contrast material), and X-rays of the barium-filled esophagus were then taken. The problem with the esophagram was that it was an insensitive test for diagnosing GERD. That is, it failed to find signs of GERD in many patients who had GERD because the patients had little or no damage to the lining of the esophagus. The X-rays were able to show only the infrequent complications of GERD, for example, ulcers and strictures. X-rays have been abandoned as a means of diagnosing GERD, although they still can be useful along with endoscopy in the evaluation of complications.

Examination of the throat and larynx

When GERD affects the throat or larynx and causes symptoms of cough, hoarseness, or sore throat, patients often visit an ear, nose, and throat (ENT) specialist. The ENT specialist frequently finds signs of inflammation of the throat or larynx. Although diseases of the throat or larynx usually are the cause of inflammation, sometimes GERD can be the cause. Accordingly, ENT specialists often try acid-suppressing treatment to confirm the diagnosis of GERD. This approach, however, has the same problems as discussed above, that result from using the response to treatment to confirm GERD.

Diagnosis

Esophageal acid testing

Esophageal acid testing is considered a “gold standard” for diagnosing GERD. As discussed previously, the reflux of acid is common in the general population. However, patients with the symptoms or complications of GERD have reflux of more acid than individuals without the symptoms or complications of GERD. Moreover, normal individuals and patients with GERD can be distinguished moderately well from each other by the amount of time that the esophagus contains acid.

The amount of time that the esophagus contains acid is determined by a test called a 24-hour esophageal pH test. (pH is a mathematical way of expressing the amount of acidity.) For this test, a small tube (catheter) is passed through the nose and positioned in the esophagus. On the tip of the catheter is a sensor that senses acid. The other end of the catheter exits the nose, wraps back over the ear, and travels down to the waist, where it is attached to a recorder. Each time acid refluxes back into the esophagus from the stomach, it stimulates the sensor, and the recorder records the episode of reflux. After a 20- to 24-hour period of time, the catheter is removed and the record of reflux from the recorder is analyzed.

There are problems with using pH testing for diagnosing GERD. Despite the fact that normal individuals and patients with GERD can be separated fairly well on the basis of pH studies, the separation is not perfect. Therefore, some patients with GERD will have normal amounts of acid reflux and some patients without GERD will have abnormal amounts of acid reflux. It requires something other than the pH test to confirm the presence of GERD, for example, typical symptoms, response to treatment, or the presence of complications of GERD. GERD also may be confidently diagnosed when episodes of heartburn correlate with acid reflux as shown by acid testing.

pH testing has uses in the management of GERD other than just diagnosing GERD. For example, the test can help determine why GERD symptoms do not respond to treatment. Perhaps 10 to 20 percent of patients will not have their symptoms substantially improved by treatment for GERD. This lack of response to treatment could be caused by ineffective treatment. This means that the medication is not adequately suppressing the production of acid by the stomach and is not reducing acid reflux. Alternatively, the lack of response can be explained by an incorrect diagnosis of GERD. In both of these situations, the pH test can be very useful. If testing reveals substantial reflux of acid while the medication is continued, then the treatment is ineffective and will need to be changed. If testing reveals good acid suppression with minimal reflux of acid, the diagnosis of GERD is likely to be wrong and other causes for the symptoms need to be sought.

pH testing also can be used to help evaluate whether reflux is the cause of symptoms (usually heartburn). To make this evaluation, while the 24-hour ph testing is being done, patients record each time they have symptoms. Then, when the test is being analyzed, it can be determined whether or not acid reflux occurred at the time of the symptoms. If reflux did occur at the same time as the symptoms, then reflux is likely to be the cause of the symptoms. If there was no reflux at the time of symptoms, then reflux is unlikely to be the cause of the symptoms.

Lastly, pH testing can be used to evaluate patients prior to endoscopic or surgical treatment for GERD. As discussed above, some 20% of patients will have a decrease in their symptoms even though they don’t have GERD (the placebo effect). Prior to endoscopic or surgical treatment, it is important to identify these patients because they are not likely to benefit from the treatments. The pH study can be used to identify these patients because they will have normal amounts of acid reflux.

A newer method for prolonged measurement (48 hours) of acid exposure in the esophagus utilizes a small, wireless capsule that is attached to the esophagus just above the LES. The capsule is passed to the lower esophagus by a tube inserted through either the mouth or the nose. After the capsule is attached to the esophagus, the tube is removed. The capsule measures the acid refluxing into the esophagus and transmits this information to a receiver that is worn at the waist. After the study, usually after 48 hours, the information from the receiver is downloaded into a computer and analyzed. The capsule falls off of the esophagus after 3-5 days and is passed in the stool. (The capsule is not reused.)

The advantage of the capsule over standard pH testing is that there is no discomfort from a catheter that passes through the throat and nose. Moreover, with the capsule, patients look normal (they don’t have a catheter protruding from their noses) and are more likely to go about their daily activities, for example, going to work, without feeling self-conscious. Because the capsule records for a longer period than the catheter (48 versus 24 hours), more data on acid reflux and symptoms are obtained. Nevertheless, it is not clear whether obtaining additional information is important.

Capsule pH testing is expensive. Sometimes the capsule does not attach to the esophagus or falls off prematurely. For periods of time, the receiver may not receive signals from the capsule, and some of the information about the reflux of acid may be lost. Occasionally there is pain with swallowing after the capsule has been placed, and the capsule may need to be removed endoscopically. The use of the capsule is an exciting use of new technology although it has its own specific problems.

Esophageal motility testing

Esophageal motility testing determines how well the muscles of the esophagus are working. For motility testing, a thin tube (catheter) is passed through a nostril, down the back of the throat, and into the esophagus. On the part of the catheter that is inside the esophagus are sensors that sense pressure. Pressure is generated within the esophagus that is detected by the sensors on the catheter when the muscle of the esophagus contracts. The end of the catheter that protrudes from the nostril is attached to a recorder that records the pressure. During the test, the pressure at rest and the relaxation of the lower esophageal sphincter are evaluated. The patient then swallows sips of water to evaluate the contractions of the esophagus.

Esophageal motility testing has two important uses in evaluating GERD. The first is in evaluating symptoms that do not respond to treatment for GERD since the abnormal function of the esophageal muscle sometimes causes symptoms that resemble the symptoms of GERD. Motility testing can identify some of these abnormalities and lead to a diagnosis of an esophageal motility disorder. The second use is evaluation prior to surgical or endoscopic treatment for GERD. In this situation, the purpose is to identify patients who also have motility disorders of the esophageal muscle. The reason for this is that in patients with motility disorders, some surgeons will modify the type of surgery they perform for GERD.

Gastric emptying studies

Gastric emptying studies are studies that determine how well food empties from the stomach. As discussed above, about 20 % of patients with GERD have slow emptying of the stomach which may be contributing to the reflux of acid. For gastric emptying studies, the patient eats a meal that is labeled with a radioactive substance. A sensor that is similar to a Geiger counter is placed over the stomach to measure how quickly the radioactive substance in the meal empties from the stomach.

Information from the emptying study can be useful for managing patients with acid reflux disease. For example, if a patient with acid reflux disease continues to have symptoms despite treatment with the usual medications, doctors might prescribe other medications that speed-up emptying of the stomach. Alternatively, in conjunction with acid reflux disease surgery, they might do a surgical procedure that promotes a more rapid emptying of the stomach. Nevertheless, it is still debated whether a finding of reduced gastric emptying should prompt changes in the surgical treatment of acid reflux disease.

Symptoms of nausea, vomiting, and regurgitation may be due either to abnormal gastric emptying or GERD. An evaluation of gastric emptying, therefore, may be useful in identifying patients whose symptoms are due to abnormal emptying of the stomach rather than to acid reflux disease.

Acid perfusion test

The acid perfusion (Bernstein) test is used to determine if chest pain is caused by acid reflux. For the acid perfusion test, a thin tube is passed through one nostril, down the back of the throat, and into the middle of the esophagus. A dilute, acid solution and a physiologic salt solution (similar to the fluid that bathes the body’s cells) are alternately poured (perfused) through the catheter and into the esophagus. The patient is unaware of which solution is being infused. If the perfusion with acid provokes the patient’s usual pain and perfusion of the salt solution produces no pain, it is likely that the patient’s pain is caused by acid reflux.

The acid perfusion test, however, is used only rarely. A better test for correlating pain and acid reflux is a 24-hour esophageal pH or pH capsule study during which patients note when they are having pain. It then can be determined from the pH recording if there was an episode of acid reflux at the time of the pain. This is the preferable way of deciding if acid reflux is causing a patient’s pain. It does not work well, however, for patients who have infrequent pain, for example, every 2-3 days, which may be missed by a 1-2-day pH study. In these cases, an acid perfusion test may be reasonable.

Allopathic treatment for Acid Reflux Disease (GERD)

There is a variety of over the counter (for example, antacids and foam barriers) and prescription medications (for example, proton pump inhibitors, histamine antagonists, and promotility drugs) for treating acid reflux disease.

Antacids for GERD

Despite the development of potent medications for the treatment of acid reflux disease, antacids remain a mainstay of allopathic treatment. Antacids neutralize the acid in the stomach so that there is no acid to reflux. The problem with antacids is that their action is brief. They are emptied from the empty stomach quickly, in less than an hour, and the acid then re-accumulates.

The best way to take antacids, therefore, is approximately one hour after meals, which is just before the symptoms of reflux begin after a meal. Since the food from meals slows the emptying from the stomach, an antacid taken after a meal stays in the stomach longer and is effective longer. For the same reason, a second dose of antacids approximately two hours after a meal takes advantage of the continuing post-meal slower emptying of the stomach and replenishes the acid-neutralizing capacity within the stomach.

Antacids may be aluminum, magnesium, or calcium-based. Calcium-based antacids (usually calcium carbonate), unlike other antacids, stimulate the release of gastrin from the stomach and duodenum.

Gastrin is the hormone that is primarily responsible for the stimulation of acid secretion by the stomach. Therefore, the secretion of acid rebounds after the direct acid-neutralizing effect of the calcium carbonate is exhausted. The rebound is due to the release of gastrin, which results in an overproduction of acid. Theoretically at least, this increased acid is not good for acid reflux disease.

Acid rebound, however, is not clinically important. That is, treatment with calcium carbonate is not less effective or safe than treatment with antacids not containing calcium carbonate. Nevertheless, the phenomenon of acid rebound is theoretically harmful. In practice, therefore, calcium-containing antacids such as Tums and Rolaids are not recommended for frequent use. The occasional use of these calcium carbonate-containing antacids, however, is not believed to be harmful. The advantages of calcium carbonate-containing antacids are their low cost, the calcium they add to the diet, and their convenience as compared to liquids.

Aluminum-containing antacids tend to cause constipation, while magnesium-containing antacids tend to cause diarrhea. If diarrhea or constipation becomes a problem, it may be necessary to switch antacids, or use antacids containing both aluminum and magnesium.

Histamine antagonists

Although antacids can neutralize acid, they do so for only a short period. For substantial neutralization of acid throughout the day, antacids would need to be given frequently, at least every hour.

The first medication developed for the more effective and convenient treatment of acid-related diseases, including acid reflux disease, was a histamine antagonist, specifically cimetidine. Histamine is an important chemical because it stimulates acid production by the stomach. Released within the wall of the stomach, histamine attaches to receptors (binders) on the stomach’s acid-producing cells and stimulates the cells to produce acid. Histamine antagonists work by blocking the receptor for histamine and thereby preventing histamine from stimulating the acid-producing cells. (Histamine antagonists are referred to as H2 antagonists because the specific receptor they block is the histamine type 2 receptor.)

As histamine is particularly important for the stimulation of acid after meals, H2 antagonists are best taken 30 minutes before meals. The reason for this timing is so that the H2 antagonists will be at peak levels in the body after the meal when the stomach is actively producing acid. H2 antagonists also can be taken at bedtime to suppress the nighttime production of acid.

H2 antagonists are very good for relieving the symptoms of acid reflux disease, particularly heartburn. However, they are not very good for healing the inflammation (esophagitis) that may accompany acid reflux disease. They are used primarily for the treatment of heartburn in acid reflux disease that is not associated with inflammation or complications, such as erosions or ulcers, strictures, or Barrett’s esophagus.Acid - Reflux - Disease - - dr - Qaisar - Ahmed - dixe - cosmetics

Three different H2 antagonists are available by prescription, including cimetidine (Tagamet), nizatidine, and famotidine. Two of these, cimetidine (Tagamet HB) and famotidine are available over the counter (OTC), without the need for a prescription.

The OTC dosages are lower than those available by prescription.

Proton pump inhibitors

The second type of drug developed specifically for acid-related diseases, such as acid reflux disease, was a proton pump inhibitor (PPI), specifically, omeprazole. A PPI blocks the secretion of acid into the stomach by the acid-secreting cells. The advantage of a PPI over an H2 antagonist is that the PPI shuts off acid production more completely and for a longer period of time. Not only is the PPI good for treating the symptom of heartburn, but it also is good for protecting the esophagus from acid so that esophageal inflammation can heal.

PPIs are used when H2 antagonists do not relieve symptoms adequately or when complications of acid reflux disease such as erosions or ulcers, strictures, or Barrett’s esophagus exist. Five different PPIs are approved for the treatment of acid reflux disease, including:

  • omeprazole
  • lansoprazole
  • rabeprazole
  • pantoprazole
  • esomeprazole
  • dexlansoprazole.

A sixth PPI product consists of a combination of omeprazole and sodium bicarbonate. PPIs are best taken an hour before meals. The reason for this timing is that the PPIs work best when the stomach is most actively producing acid, which occurs after meals. If the PPI is taken before the meal, it is at peak levels in the body after the meal when the acid is being made.

Promotility drugs

Promotility drugs work by stimulating the muscles of the gastrointestinal tract, including the esophagus, stomach, small intestine, and/or colon. One pro-motility drug, metoclopramide, is approved for acid reflux disease. Promotility drugs increase the pressure in the lower esophageal sphincter and strengthen the contractions (peristalsis) of the esophagus. Both effects would be expected to reduce the reflux of acid. However, these effects on the sphincter and esophagus are small. Therefore, it is believed that the primary effect of metoclopramide may be to speed up the emptying of the stomach, which also would be expected to reduce reflux.

Promotility drugs are most effective when taken 30 minutes before meals and again at bedtime. They are not very effective for treating either the symptoms or complications of acid reflux disease. Therefore, the pro-motility agents are reserved either for patients who do not respond to other treatments or are added to enhance other treatments for acid reflux disease.

Foam Barriers

Foam barriers provide a unique form of treatment for acid reflux disease. Foam barriers are tablets that are composed of an antacid and a foaming agent. As the tablet disintegrates and reaches the stomach, it turns into foam that floats on top of the liquid contents of the stomach. The foam forms a physical barrier to the reflux of liquid. At the same time, the antacid bound to the foam neutralizes acid that comes into contact with the foam. The tablets are best taken after meals (when the stomach is distended) and when lying down, both times when reflux is more likely to occur. Foam barriers are not often used as the first or only treatment for acid reflux disease. Rather, they are added to other drugs for GERD when the other drugs are not adequately effective in relieving symptoms. There is only one foam barrier, which is a combination of aluminum hydroxide gel, magnesium trisilicate, and alginate.

Surgical procedures

The allopathic drugs described above usually are effective in treating the symptoms and complications of GERD not the cause of disease. However, sometimes they are not. For example, despite adequate suppression of acid and relief from heartburn, regurgitation, with its potential for complications in the lungs, may still occur. Moreover, the amounts and/or numbers of drugs that are required for satisfactory treatment are sometimes so great that drug treatment is unreasonable. Allopathically in such situations, surgery is the last option for allopathic physicians.

Surgery

The surgical procedure that is done to prevent reflux is technically known as fundoplication and is called reflux surgery or anti-reflux surgery. During fundoplication, any hiatal hernial sac is pulled below the diaphragm and stitched there. In addition, the opening in the diaphragm through which the esophagus passes is tightened around the esophagus. Finally, the upper part of the stomach next to the opening of the esophagus into the stomach is wrapped around the lower esophagus to make an artificial lower esophageal sphincter.

This surgery can be done through an incision in the abdomen (laparotomy) or using a technique called laparoscopy. During laparoscopy, a small viewing device and surgical instruments are passed through several small puncture sites in the abdomen. This procedure avoids the need for a major abdominal incision.

Surgery is very effective at relieving symptoms and treating the complications of GERD. Approximately 80% of patients will have good or excellent relief of their symptoms for at least 5-10 years. Nevertheless, many patients who have had surgery will continue to take drugs for reflux.

It is not clear whether they take the drugs because they continue to have reflux and symptoms of the reflux or if they take them for symptoms that are being caused by problems other than acid reflux disease.

The most common complication of fundoplication is swallowed food that sticks to the artificial sphincter. If it is transient, endoscopic treatment to stretch (dilate) the artificial sphincter usually will relive the problem. Occasionally it is necessary to reoperate to revise the prior surgery.
