What causes lower abdominal pain?
Often, lower abdominal pain is related to conditions of the digestive tract, but can also be related to conditions of the body wall, skin, blood vessels, urinary tract, or reproductive organs.
Digestive tract causes of lower abdominal pain
Lower abdominal pain may be caused by digestive tract conditions including:
- Bacterial, parasitic or viral infection of the gastrointestinal tract
- Celiac disease (severe sensitivity to gluten from wheat and other grains that causes intestinal damage)
- Chronic constipation
- Diverticulitis (inflammation of an abnormal pocket in the colon)
- Food intolerance such as lactose intolerance (inability to digest lactose, the sugar in dairy products)
- Inflammatory bowel disease (includes Crohn’s disease and ulcerative colitis)
- Irritable bowel syndrome (IBS; digestive discomfort that does not cause intestinal damage or serious disease)
- Meckel’s diverticulum (congenital, abnormal pouch near the lower end of the small intestine)
Other causes of lower abdominal pain
Lower abdominal pain can also be caused by conditions of other body systems including:
- Abdominal hernia (weakened area of the abdominal wall, through which internal organs can pass)
- Cancer of an abdominal or pelvic organ
- Endometriosis (condition where tissues resembling the uterine lining grow in other areas of the body)
- Kidney stones
- Menstrual cramps
- Ovarian cysts (benign sacs in an ovary that contain fluid, air, or other materials)
- Pelvic inflammatory disease (PID; infection of a woman’s reproductive organs)
- Shingles (painful, blistering rash, often forming a stripe, resulting from a reactivation of the varicella-zoster, or chickenpox, virus)
- Urinary tract infection
- Uterine fibroids (abnormal growths of uterine muscle tissue that can cause uterine enlargement or discomfort)
Serious or life-threatening causes of lower abdominal pain
In some cases, lower abdominal pain may be a symptom of a serious or life-threatening condition that should be immediately evaluated in an emergency setting. These include:
- Abdominal abscess
- Bowel obstruction or perforation
- Colonic volvulus (twisting of the colon)
- Ectopic pregnancy (life-threatening pregnancy growing outside the uterus)
- Intestinal ischemia (loss of blood supply to the intestines leading to death of intestinal tissue)
- Intussusception (telescoping of the intestines into themselves, which can cause intestinal ischemia)
- Occlusion, embolism, or thrombosis of the mesenteric artery
- Ovarian torsion (twisting of the ovary)
- Peritonitis (infection of the lining that surrounds the abdomen)
- Ruptured appendix
- Significant abdominal trauma
- Testicular injury
- Testicular torsion (twisting of the spermatic cord)
