Inflammatory bowel disease management
Your doctor will likely diagnose inflammatory bowel disease only after ruling out other possible causes for your signs and symptoms. To help confirm a diagnosis of IBD, you may have one or more of the following tests and procedures:
- Tests for anemia or infection. Your doctor may suggest blood tests to check for anemia — a condition in which there aren’t enough red blood cells to carry adequate oxygen to your tissues — or to check for signs of infection from bacteria or viruses.
- Fecal occult blood test. You may need to provide a stool sample so that your doctor can test for hidden blood in your stool.
- Colonoscopy. This exam allows your doctor to view your entire colon using a thin, flexible, lighted tube with an attached camera. During the procedure, your doctor can also take small samples of tissue (biopsy) for laboratory analysis. Sometimes a tissue sample can help confirm a diagnosis.
- Flexible sigmoidoscopy. Your doctor uses a slender, flexible, lighted tube to examine the rectum and sigmoid, the last portion of your colon. If your colon is severely inflamed, your doctor may perform this test instead of a full colonoscopy.
