I often sufer with acidity. what is the cure?

Heartburn: Do you mean heartburn? The most natural way to help the symptoms is to try to avoid foods and drinks that could aggravate it: alcohol, caffeine, high fat foods, spicy foods, tomato juice. Avoid lying down within 2-3 hours of a meal. If you're still having symptoms, then you can try otc Tums (calcium carbonate) or antacids. If still not improving, then consulting with a gastroenterologist may help.
