How to Diagnose Irritable Bowel Syndrome
The doctor will ask about your symptoms and medical history, and perform a physical exam. In many cases, a diagnosis can be made based on this. Since there is no diagnostic test for IBS, doctors have created criteria for making a diagnosis.
Your doctor may order the following tests to rule out other conditions:
- Analysis of a stool sample to check for blood or evidence of inflammation
- Blood tests
- Barium enema -injection of fluid into the rectum to make the colon show up on an an x-ray , allows the doctor to see abnormal spots in the colon
- Flexible sigmoidoscopy -a thin, lighted tube inserted into the rectum to examine the rectum and the lower colon
- Colonoscopy -a thin, lighted tube inserted through the rectum and into the colon to examine the lining of the entire colon
Your doctor may also screen you for Celiac Disease , which is more common in people with IBS.
