Gastroesophageal reflux disease
Information, Symptoms, Treatments and Resources
Gastroesophageal reflux disease (GERD) is a condition in which food or liquid travels backwards from the stomach to the esophagus (the tube from the mouth to the stomach). This action can irritate the esophagus, causing heartburn and other symptoms.
Gastroesophageal reflux is a common condition that often occurs without symptoms after meals. In some people, the reflux is related to a problem with the lower esophageal sphincter, a band of muscle fibers that usually closes off the esophagus from the stomach. If this sphincter doesn't close properly, food and liquid can move backward into the esophagus and may cause the symptoms.
The risk factors for reflux include hiatal hernia, pregnancy, and scleroderma.
A number of studies suggest that obesity contributes to gastroesophageal reflux. For instance, the Nurses Health Study found that being overweight or obese significantly increased reflux symptoms in women. (Women who lost weight in the study, meanwhile, had fewer symptoms.)

- A positive stool guaiac
- Continuous esophageal pH monitoring showing reflux
- Endoscopy showing ulceration or inflammation of the esophagus
- Esophageal manometry showing abnormal sphincter pressure
- A barium swallow showing reflux
- A positive Bernstein test for gastric acid reflux
General measures include:
- Weight reduction
- Avoiding lying down after meals
- Sleeping with the head of the bed elevated
- Taking medication with plenty of water
- Avoiding dietary fat, chocolate, caffeine, peppermint (they may cause lower esophageal pressure)
- Avoiding alcohol and tobacco
- Antacids after meals and at bedtime
- Histamine H2 receptor blockers
- Promotility agents
- Proton pump inhibitors
The majority of people respond to nonsurgical measures with behavioral modification and medications.
- Inflammation of the esophagus
- Stricture
- Esophageal ulcer
- Hoarseness, bronchospasm
- Chronic pulmonary disease
- Barrett's esophagus (a change in the lining of the esophagus that can increase the risk of cancer)
