- 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)
Other causes of left lower quadrant pain
Left lower quadrant pain can also be caused by conditions involving 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)
