Acid reflux disease or, more properly, gastroesophageal reflux disease (GERD) is a digestive system disorder where stomach acid splashes on the bottom of the esophagus. It is typified by a severe burning sensation in the chest, usually after meals, usually several times a week. Although it is not particularly dangerous, it can be a chronic problem and can lead to damage to the esophagus and even esophageal cancer.
Acid reflux is usually managed through medication and diet change. Patients should avoid overeating and foods that produce a great deal of stomach acid, such as deep-fried foods. Mild symptoms can be treated with antacids (such as Tums(TM)), or foaming agents that protect the esophagus (such as Gaviscon(TM)). However, for serious conditions, proton-pump inhibitors which reduce stomach acid production such as Losec(TM) are indicated.
