Gastroesophageal reflux disease (GERD) is a condition in which the stomach contents (food or liquid) leak backwards from the stomach into the esophagus (the tube from the mouth to the stomach). This action can irritate the esophagus, causing heartburn and other symptoms.
When you eat, food passes from the throat to the stomach through the esophagus. Once food is in the stomach, a ring of muscle fibers prevents food from moving backward into the esophagus. These muscle fibers are called the lower esophageal sphincter, or LES.
If this sphincter muscle doesn’t close well, food, liquid, and stomach acid can leak back into the esophagus. This is called reflux or gastroesophageal reflux. Reflux may cause symptoms, or it can even damage the esophagus.
The risk factors for reflux include:
More common symptoms are:

Exams and Tests
You may not need any tests if your symptoms are not severe.
If your symptoms are severe or they come back after you have been treated, one or more tests may help diagnose reflux or any complications:
A positive stool occult blood test may diagnose bleeding that is coming from the irritation in the esophagus, stomach, or intestines.
You can make many lifestyle changes to help treat your symptoms. Avoid foods that cause problems for you. Making changes to your routine before you go to sleep may also help.
Avoid drugs such as aspirin, ibuprofen (Advil, Motrin), or naproxen (Aleve, Naprosyn). Take acetaminophen (Tylenol) to relieve pain. Take your medicines with plenty of water. When your doctor gives you a new medicine, remember to ask whether it will make your heartburn worse.
You may use over-the-counter antacids after meals and at bedtime, although they do not last very long. Common side effects of antacids include diarrhea or constipation.
Other over-the-counter and prescription drugs can treat GERD. They work more slowly than antacids but give you longer relief. Your pharmacist, doctor, or nurse can tell you how to take these drugs.
Anti-reflux operations (fundoplication and others) may be an option for patients whose symptoms do not go away with lifestyle changes and drugs. Heartburn and other symptoms should improve after surgery, but you may still need to take drugs for your heartburn.
There are also new therapies for reflux that can be performed through an endoscope (a flexible tube passed through the mouth into the stomach).
