Acute Abdominal Pain Causes, Symptoms, Treatment, Prevention


Acute Abdominal Pain


Acute abdomen is the medical term used for pain in the abdomen that usually comes on suddenly and is so severe that one may have to go to the hospital. Acute abdominal pain refers to pain with sudden onset and duration of less than 48 hours, while chronic abdominal pain lasts longer than two weeks.

Acute abdominal pain is very common, with up to 20% of people experiencing abdominal pain in the past year. Up to 90% of cases are of minor significance and resolve in 2-3 weeks on their own. However, there are many life-threatening causes of abdominal pain, leading to potential consequences such as bowel performation, ischemia, or sepsis. As such, clinicians need to have a high index of suspicion for concern when evaluating abdominal pain.

Abdominal pain is common and often minor. Severe abdominal pain that comes on quickly, however, almost always indicates a significant problem.  Acute abdominal pain can signal a variety of more serious conditions, some of which require immediate medical care and/or surgery.

Causes of Acute Abdominal Pain


There are a number of possible causes of acute abdomen. These may include:

                      - Menstrual cramps
                      - Endometriosis
                      - Uterine fibroids
                      - Ovarian cysts
                      - Pelvic inflammatory disease - inflammation around the ovaries, uterus, and fallopian tubes
                      - Miscarriage or ectopic pregnancy
  • In infants:
                      - Intussusception  - the telescoping of one portion of the intestine into another, causing obstruction of the bowel and blockage of its blood flow
                      - Volvulus - a twisting of the colon around itself
                      - Hirschsprung's disease - also known as congenital megacolon
                      - Other congenital defects of the digestive tract
