10 Common Causes of Abdominal Pain

3. Indigestion

Indigestion is constant pain in the upper abdomen caused by the acid of the stomach. When you consume food, your stomach produces acid to help breakdown and digest the food. Sometimes, the acid may be too powerful, causing a burning sensation in some parts of the digestive system, especially the upper part of the bowel (also known as the esophagus). Sometimes the pain is felt immediately after eating, while in other occasions there may be a delay between eating and indigestion. Besides a burning sensation in the esophagus, indigestion may also make you feel bloated full.
