Capsule endoscopy is a safe procedure that carries few risks. Most of the time, the capsule will be passed out through your stools within a few days. However, there are occasions when the capsule may become stuck in your digestive tract. The risk may be higher in people with a narrowed intestine or a polyp, as these may cause the capsule to be lodged in your digestive tract.
If the capsule does not get passed in your stool, your doctor may request for additional scans to ensure it is no longer in your body. If it gets stuck and causes symptoms of bowel obstruction, it must be removed, either through surgery or an endoscopic procedure.
