By Mayo Clinic staffMost of the time, it's difficult to determine where abdominal pain originates from. And though you may feel pain in one area of your abdomen, it may actually be caused by something in another area of your body — what doctors call referred pain. Few causes of abdominal pain are specific to one area of your abdomen.
Some abdominal pain isn't focused in one area of the abdomen. This type of pain can be caused by:
- Aortic aneurysm
- Appendicitis
- Crohn's disease
- Diabetic ketoacidosis (high levels of ketones in the blood)
- Diverticulitis
- Injury
- Intestinal obstruction
- Intussusception (in children)
- Irritable bowel syndrome
- Lead poisoning
- Mesenteric lymphadenitis (swollen lymph nodes in the folds of membrane that hold the abdominal organs in place)
- Pancreatitis (pancreas inflammation)
- Pelvic inflammatory disease (PID) (infection of the female reproductive organs)
- Peritonitis (infection of the abdominal lining)
- Sickle cell anemia
- Strained or pulled abdominal muscle
- Ulcerative colitis
- Uremia (buildup of waste products in your blood)
- Urinary tract infection
- Viral gastroenteritis (stomach flu) (stomach inflammation)
Causes of lower abdominal pain, sometimes described as pelvic pain, include:
- Appendicitis
- Cystitis (bladder inflammation)
- Diverticulitis
- Ectopic pregnancy
- Endometriosis
- Intestinal obstruction
- Mittelschmerz (pain associated with ovulation)
- Ovarian cysts
