Abdominal pain, also known as stomach pain, 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.

In about 30% of cases, the cause is not determined. About 10% of cases have a more serious cause including gallbladder (stones or biliary dyskinesia) or pancreas problems (4%), diverticulitis (3%), appendicitis (2%) and cancer (1%). More common in those who are older, mesenteric ischemia and abdominal aortic aneurysms are other serious causes.
