How is inflammatory bowel disease diagnosed?
Based on your symptoms, your doctor may suspect that you have Crohn's disease or ulcerative colitis. Your bowel movements may be tested for germs and the presence of blood. Your doctor will probably look inside your intestines with a sigmoidoscope or a colonoscope. In these procedures, the doctor uses a narrow flexible tube to look directly inside your intestines.
While no blood test can prove you have IBD, your blood might show anemia, salt imbalance, vitamin deficiency or increased signs of inflammation. Your doctor also may order special x-rays or a procedure called endoscopy. Endoscopy lets your doctor look at your GI tract to check for ulcers by inserting a small scope into your body through your mouth or anus.
