How is irritable bowel syndrome with diarrhea (IBS-D) diagnosed?

ANSWER

There isn’t a test that tells you if you have IBS-D (or any kind of IBS). Instead, your doctor will look at your health history and symptoms. If you’ve had abdominal pain and other signs of IBS for at least 3 months, you may have it. If you have other symptoms, like rectal bleeding, weight loss, or a family history of gastrointestinal cancer, your doctor may want you to have tests to rule out other possibilities.

These can include a blood test to check for celiac disease and a colonoscopy to check for abnormal growths and signs of cancer.
