==Overview==
==Overview==
The causes of abdominal pain vary with the distribution of the pain. The distribution can be determined by various methods, such as into either abdominal quadrants or nine sections.
Life threatening causes of abdominal pain include [[acute peritonitis]], [[bowel obstruction]], [[diabetic ketoacidosis]] and [[testicular torsion]]. Other common causes of abdominal pain include [[appendicitis]], [[constipation]], [[dysmenorrhea]] and  [[lactose intolerance]].
