Gastroesophageal Reflux (GERD) / Acid Reflux

What is Reflux?

Gastroesophageal reflux disease (GERD) is a condition in which the stomach's juices (acid and digestive enzymes) flow backwards, or reflux, into the esophagus (swallowing tube). Because the lining of the esophagus is not equipped to handle these caustic substances, the esophagus becomes inflamed. This produces the sensation we call heartburn as well as other symptoms of esophageal irritation. Over time, untreated GERD may even lead to permanent esophageal damage.

The underlying problem in GERD almost always involves the esophageal sphincter (LES). The LES is a high pressure zone at the lower end of the esophagus near the entrance to the stomach. Under normal circumstances, the LES keeps the stomach's contents from flowing backwards into the esophagus by opening only when you are eating or swallowing. The rest of the time, the LES acts like a protective valve and remains tightly shut.

In patients with GERD, the LES either does not squeeze tightly or opens at the wrong time, allowing digestive juices to reflux into the esophagus and irritate the esophageal lining. Prolonged exposure to acid can cause esophagitis (inflammation of the esophagus), narrowing of the esophagus or an esophageal ulcer. Chronic acid exposure can also lead to Barrett's esophagus, a condition in which the normal lining of the esophagus is replaced by inflamed tissue. Barrett's esophagus is considered a potentially precancerous condition; 2 percent to 5 percent of patients with Barrett's esophagus eventually develop cancer of the esophagus.

About 40% of the US population has heartburn at least once a month. An estimated 17 million Americans (7%) currently suffer from heartburn and other symptoms of GERD every day.


Symptoms

Symptoms of GERD may include:

 

Diagnosis

GERD is diagnosed mostly by a careful interview of your symptoms. This includes the frequency and characteristics of your symptoms, and what makes your symptoms worse or better. Because heartburn like pain can also be a symptom of coronary artery disease, your doctor may ask whether you have any cardiac symptoms (shortness of breath, palpitations, dizziness) or do additional testing to help rule out this problem. Depending on your symptoms, lifestyle changes (see Prevention) and a trial of over-the-counter medications may be recommend prior to beginning any specialized diagnostic testing.

If you have more serious symptoms (such as severe heartburn, difficulty swallowing, painful swallowing, or weight loss) or if your heartburn is not relieved by medications, then further testing is required. The best way to visualize the esophagus is with esophagoscopy, a form of endoscopy (visual inspection with an instrument called an endoscope). Esophagoscopy allows the doctor to inspect the inside of your esophagus and, if necessary, to take a biopsy (a tissue sample for laboratory analysis). During esophagoscopy, your doctor looks for evidence of esophageal inflammation, erosions, ulcers, strictures or the color changes of Barrett's esophagus. To eliminate other possible causes of your symptoms, the scope may be used to visualize the stomach and first part of the small intestines. The following tests may be ordered in addition to esophagoscopy:

 

When Should I See a Doctor?

Without treatment, GERD is typically a long-term problem that relapses and recurs over many years. In fact, studies have shown that the average GERD patient endures symptoms for one to three years before seeing a doctor. This is unfortunate, because medical and surgical treatments are very effective in treating this condition. You should see your doctor immediately if you have any of the following symptoms:

 

Prevention

There is much that you can do to prevent the symptoms of GERD. Some simple lifestyle changes include: At night, elevate the head of your bed at least six inches. If possible, put wooden blocks under the legs at the head of the bed or use a solid foam wedge under the head portion of the mattress. Simply using extra pillows may not help. Avoid foods that promote acid reflux, especially coffee, chocolate, fatty foods, spicy foods, carbonated beverages, peppermint, spearmint, citrus fruits, tomatoes, whole milk and onions. Eat smaller, more frequent meals. Do not lie down after eating. Do not eat for three to four hours before going to bed. Quit smoking, this includes all nicotine containing products. Avoid drinking alcohol. Lose weight if you are obese. Obesity can make it harder for the LES to stay closed. Avoid wearing tight-fitting garments. These increase pressure on the abdomen, opening the LES when it should be shut.

 

Treatment

For many people, the first step is lifestyle modification as described above. Drug therapy includes over-the-counter antacids and acid-blocking drugs and prescription-strength drugs that target symptoms in different ways. Procedural treatments such as the laparoscopic Nissen fundoplication and the Esophyx procedure attempt to decrease the amount of fluid that refluxes into the esophagus.

Over-the-counter antacids — These include Mylanta, Maalox, Tums, Rolaids, Gaviscon and others. The liquid forms of these medications work faster, but the tablets are more convenient. Because the magnesium-containing antacids may cause diarrhea and the aluminum-containing antacids may cause constipation, your doctor may advise you to alternate antacids to avoid these problems. Although these drugs neutralize acid, they do not heal the inflammation of the esophagus. Note: If you are pregnant, always check with your doctor before you take antacids or any other medication.

Over-the-counter H2 blockers — These drugs work by causing the stomach to make less acid, and they are effective in patients with mild to moderate symptoms. They include famotidine (Pepcid-AC), cimetidine (Tagamet HB), ranitidine (Zantac 75) and Prilosec OTC. Because of a phenomenon called "up regulation", after prolonged regular use these drugs often will no longer suppress acid adequately.

 

Prescription medications — Prescription medications include:

 

Procedural treatments

Usually reserved for patients who have frequent symptoms who can not be weaned off medication and for a variety of reasons do not wish to or can not tolerate long term medical therapy. In the majority of patients the procedures are safe, well tolerated, highly effective in relieving symptoms, and have a high degree of patient satisfaction. The two procedures Dr. Fusco offers for Acid Reflux are: the Laparoscopic Nissen Fundoplication, and the Esophyx procedure.

The Esophyx procedure is a type of Natural Orifice Surgery or Incisionless Surgery. The procedure is done by altering the LES area by placing stitches from the inside of the stomach. This is done using an instrument that is placed via the mouth.

Prognosis

GERD has an excellent prognosis. Eighty to 90 percent of patients improve after treatment with medication. Laparoscopic Nissen fundoplication, even though it is typically used in patients with the most severe cases of reflux, will cure heartburn in over 90% of cases without the need for continued medication in two thirds of case.
