The upward surge of stomach acids that cause the telltale pain of heartburn can also trigger asthma attacks. One of the best ways to prevent heartburn is to eat four or more small meals daily, instead of two or three large meals, Dr. Plaut advises. Also, don't eat just before bedtime. To help prevent stomach acid from going "upstream," raise the head of your bed 4 to 6 inches by putting blocks under the legs of the bed.
You can also quell heartburn with over-the-counter antacids or with acid-suppressing drugs such as cimetidine (Tagamet).
