Endoscopic Examination of the Small Intestine with Capsule Endoscopy (Small Bowel Capsule Endoscopy)

What to Expect Before the Procedure

You’ll likely be given special instructions to prepare, such as fasting for a few hours before the test. You may also need to avoid certain medications or foods. Your doctor will explain how to take the capsule and what to do afterward. The capsule is swallowed with water and travels naturally through your digestive system. It doesn’t hurt, but you may feel some mild discomfort as it moves through your stomach and intestines. You’ll need to stay hydrated and avoid drinking for a short time after swallowing it to ensure it passes smoothly.

During the Procedure

The capsule records images as it moves through your small intestine. You’ll carry a small recording device to wear around your waist, which captures these images. You’ll need to stay active and walk around for about 8 hours to help the capsule move through your digestive tract. The images are reviewed by a specialist after the procedure to identify any abnormalities.

After the Procedure

After completing the capsule’s journey, you’ll need to return the recording device and any used capsules to your doctor. You can resume your normal diet and activities, but avoid chewing or swallowing the capsule. You may experience mild side effects like bloating or gas, which are normal. Follow-up instructions from your doctor will guide you on what to do next, such as scheduling a review of the images or any further tests if needed.

Why This Test Might Be Ordered

Your doctor may recommend a small bowel capsule endoscopy if they suspect issues like inflammatory bowel disease (such as Crohn’s disease), bleeding in the small intestine, food intolerances, or unexplained symptoms like abdominal pain, diarrhea, or weight loss. It’s particularly useful when other tests, like an upper or lower endoscopy, don’t provide enough information.
