Capsule endoscopy is a procedure that allows for visualization of the lining of the entire length of the small intestine, something that is not possible with a standard endoscopy. The capsule endoscope is an untethered capsule camera that is the size of a vitamin pill. The patient swallows the camera with a glass of water in the morning and returns in the afternoon after a normal day of activity. Throughout the procedure high-resolution images are sent from the camera to a receiver mounted on a belt worn by the patient. The capsule camera is one-time use and is passed painlessly with a bowel movement. This procedure does not require sedation. Common reasons to have capsule endoscopy include: unexplained gastrointestinal bleeding, chronic iron deficiency anemia, gluten sensitivity, and Crohn's disease.
