Abdominal pain, also known as stomach pain or stomach ache, is a common symptom associated with both temporary, non-serious disorders and more serious conditions.

Common causes of pain in the abdomen include gastroenteritis and irritable bowel syndrome. In a third of cases the exact cause is unclear. About 10% of people have a more serious underlying condition such as appendicitis, leaking or ruptured abdominal aortic aneurysm, diverticulitis, or ectopic pregnancy. Determining the cause can be difficult, because many diseases can cause this symptom.
