Ghassan Al-sabbagh MD is a gastroenterologist and hepatologist. Ghassan Al-sabbagh  explains that capsule endoscopy is a procedure that helps a gastroenterologist examine the small intestine using a tiny camera. The patient swallows the video capsule and it travels in the body, and as it does, images are sent to a recorder. It is usually performed when other procedures fail to determine the cause of common symptoms like diarrhea, anemia, abdominal pain or bleeding.
