As the capsule travels through your digestive tract, the camera takes thousands of pictures that are transmitted to a recorder you wear on a belt around your waist.
Capsule endoscopy helps doctors see inside your small intestine - an area that isn't easily reached with more-traditional endoscopy procedures.
What you need to know:
- Stop eating and drinking at least 12 hours before the procedure. This will ensure that the camera captures clear images of your digestive tract. In some cases, you may be asked to take a laxative before your capsule endoscopy to flush out your small intestine. This has been shown to improve the quality of the pictures collected by the capsule's camera.
- To keep medication from interfering with the camera, you may be asked not to take certain medications before the procedure.
- Plan to take it easy for the day. In most cases, you'll be able to go about your day after you swallow the camera capsule. But please avoid strenuous exercise or heavy lifting.
