GERD stands for Gastroesophageal Reflux Disease. Gastroesophageal reflux describes a backflow of acid from the stomach into the swallowing tube or esophagus. Almost everyone experiences gastroesophageal reflux at some time. The usual symptom is heartburn, an uncomfortable burning sensation behind the breastbone, most commonly occurring after a meal. In some individuals this reflux is frequent or severe enough to cause more significant problems, that is a disease.

The four major symptoms of GERD are: q Heartburn (uncomfortable, rising, burning sensation behind the breastbone). q Regurgitation of gastric acid or sour contents into the mouth. q Difficult and/or painful swallowing. q Chest pain. Heartburn is the most common symptom of GERD. In some patients it may be accompanied by other GERD symptoms, such as regurgitation of gastric contents into the mouth, chest pain and difficulty swallowing.

What causes GERD? GERD is caused by reflux of stomach acid into the esophagus. In most patients this is due to a transient relaxation of the "gate" or sphincter that keeps the lower end of the esophagus closed when a person is not swallowing food or liquids. This transient relaxation happens a few times each day in people without GERD. Why it happens more frequently in GERD patients isn't known. The esophagus is not able to cope with acid as well as the stomach and is easily injured.

GERD afflicts people of every socioeconomic class, ethnic group and age. However, the incidence does seem to increase quite dramatically above the age of 40. Greater than 50 percent of those afflicted with GERD are between the ages of 45-64 (both male and female).

Only a minority of patients develop complications of GERD. These complications include breaks in the lining of the esophagus (esophageal erosions), esophageal ulcer, and narrowing of the esophagus (esophageal stricture). In some patients, the normal esophageal lining or epithelium may be replaced with abnormal (Barrett's) epithelium. This condition (Barrett's esophagus) has been linked to cancer of the esophagus and must be carefully watched.

Smoking doesn't cause GERD and there is little evidence that smoking significantly worsens GERD. Stopping smoking is a good idea anyway.

Unfortunately, GERD, in general, cannot be cured at present. In some cases, it may be a temporary condition associated with a specific aggravating factor such as pregnancy. In such cases, GERD will go away on its own when the pregnancy has ended. In most cases GERD is a chronic condition. However, it can be effectively managed with medications and lifestyle modifications in almost everybody. In severe cases, surgery is an option.

If you think you might have GERD - see your doctor who can determine if you have GERD and, if so, can evaluate its severity.

GERD or Gastroesophageal Reflux Disease affects millions of people each year. This catch-all term encompasses a wide array of complaints ranging from "acidic stomach", belching, nausea, bloating, distention, heartburn, hoarseness, esophagitis, gastritis, acid reflux, and asthma-like symptoms.

Factors such as aging, over-eating, coughing, vomiting, obesity, lying down, bending forward, lifting heavy objects, straining or pregnancy can bring on the disorder.

No. GERD has probably been around as long as heartburn. The term is relatively new (about 20 years), however, and has really come into common usage over the past few years. GERD is often called "reflux," "reflux esophagitis," or sometimes even "hiatus hernia" (although hiatus hernia is a specific diagnosis that may or may not have anything to do with GERD).

Recent statistics from the US Department of Health and Human Services indicate that about seven (7) million people in the US alone suffer from GERD. (Source: Digestive Diseases in the United States: Epidemiology and Impact, National Digestive Diseases Data Working Group, James E. Everhart, MD, MPH, Editor, US Department of Health and Human Services, Public Health Service, National Institutes of Health, NIH Publication No. 94-1447, May 1994)

GERD is a disease and heartburn is its most common symptom. Heartburn is defined as a rising, burning sensation behind the breastbone caused by reflux of stomach acid into the esophagus. Nearly everyone has or will experience heartburn on occasion. Frequent heartburn that disrupts one's lifestyle suggests the diagnosis of GERD.

Hiatus hernia refers to dislocation of the stomach through the "hiatus" of the diaphragm and into the chest. This is a common condition that increases in frequency with age. It may or may not be associated with GERD. When GERD is severe enough to be complicated by erosive esophagitis, seen as breaks in the lining of the esophagus, a hiatus hernia is usually present. However, most patients with a hiatus hernia do not have GERD.

Endoscopy is a diagnostic test wherein a thin, flexible tube is swallowed by the patient to allow the physician to directly inspect the lining of the upper gastrointestinal tract. This procedure can be used to identify complications of GERD and to take small samples (biopsies) for further analysis. GERD patients who have certain symptoms, such as difficulty in swallowing or painful swallowing, should be considered for endoscopy.

The major factor is meals. Meals stimulate the stomach to produce more acid that can reflux up into the esophagus. In some patients, lying down or taking certain medications can worsen acid reflux. Spicy foods do not cause GERD, although they do seem to worsen GERD symptoms in some people. Food (in general) can make GERD worse. This is because food fills the stomach and induces more transient relaxations of the lower esophageal sphincter.
