Abdominal pain is described as pain originating from organs within the abdominal cavity (i.e., stomach, small intestine, colon, liver, gallbladder, and pancreas) or tissues/ muscle surrounding the abdominal area. Abdominal pain can be acute or chronic. The characteristics of the pain–location, timing, duration, etc. are important in diagnosing its cause. Persistent abdominal pain should be evaluated by a physician.
