  • In women, menstrual cramps, fibroids, ovarian cysts, pelvic inflammatory disease, or endometriosis

  • Inflammation or infection of the intestines, including Crohn's disease and ulcerative colitis

  • Irritable bowel syndrome

Diagnosing the cause of abdominal pain

Your healthcare provider will give you a physical exam help find the cause of your pain. If needed, you will have tests. Belly pain has many possible causes. So it can be hard to find the reason for your pain. Giving details about your pain can help. Tell your provider where and when you feel the pain, and what makes it better or worse. Also let your provider know if you have other symptoms such as:

  • Fever

  • Tiredness

  • Upset stomach (nausea)

  • Vomiting

  • Changes in bathroom habits

  • Blood in the stool or black, tarry stool

  • Weight loss that you can't explain (involuntary weight loss?)

Also report any family history of stomach or intestinal problems, or cancers. Tell your provider about all your alcohol use and drug use. Tell your provider about all medicines you use, including herbs, vitamins, and supplements.

Treating abdominal pain

Some causes of pain need emergency medical treatment right away. These include appendicitis or a bowel blockage. Other problems can be treated with rest, fluids, or medicines. Your healthcare provider can give you specific instructions for treatment or self-care based on what is causing your pain.
