Abdominal pain is any pain that is felt between the chest and groin. The term is generally used to describe pain originating from organs within the abdominal cavity such as the stomach, small intestine, colon, liver, gallbladder, and pancreas. This pain can be caused by a variety of conditions including appendicitis, diverticulitis, colitis, gallstones, and irritable bowel syndrome (IBS).
