Indigestion is a catch-all term used to describe any discomfort related to eating, including heartburn and nausea. Persistent indigestion can indicate an ulcer, a gallstone, or inflammation of the esophagus, and should prompt you to visit a doctor. Heartburn, a burning sensation in the chest and sometimes the throat or mouth, is caused by acid rising from the stomach into the esophagus. To avoid heartburn, drink sparingly during meals and eat a low-fat, high-fiber diet. Do not eat just before going to bed. Also, pass up fried and spicy foods, citrus fruits, tomatoes, alcohol, caffeine, tobacco, chocolate, mints and aspirin--all of which relax the opening at the base of the esophagus, letting acid in.

Antacids soothe heartburn as well as acid indigestion; the oldest of these is baking soda. Commercial antacids often contain calcium carbonate (which may neutralize as much as twice the acid as baking soda), aluminum hydroxide (which tends to cause constipation), and magnesium salts (which tend to have a laxative effect). Combined, magnesium salts and aluminum hydroxide are more potent, and their side effects may negate each other. Besides antacids, which neutralize stomach acid, acid reducers are now available.
