Testing for colitis typically involves examining the bowel for inflammation. Here's how that's done:
Initial Examination: Sigmoidoscopy
- A sigmoidoscopy is often the first step. This procedure involves inserting a sigmoidoscope, which is a thin, flexible tube with a camera, into your rectum.
- The camera allows the doctor to examine the level and extent of bowel inflammation, which is crucial for diagnosing ulcerative colitis, according to the provided reference.
