What tests do doctors use to determine if you have celiac disease or irritable bowel syndrome (IBS)?

ANSWER

If you have severe stomach pain, diarrhea, or gas right after you eat certain foods, see your doctor. Tell her when your symptoms started and what seems to trigger them. She'll probably want to do a few tests to find out what the problem is. These tests could include:

There is no test for irritable bowel syndrome (IBS). Your doctor will go over your symptoms to rule out other causes like celiac disease, Crohn's disease, or ulcerative colitis. If you don't have any of those, you probably have IBS.

  • Blood test: This may show if you have celiac antibodies or low blood counts, which is a sign of anemia.
  • Endoscopy: Your doctor will look for damage to your small intestine through a long, lighted tube. He also might take a sample of tissue (called a biopsy) to test for signs of celiac disease.
  • Bone density test: This is a low-dose X-ray that shows how much mineral is in your bones. It can predict how strong your bones are and how likely they are to break.
