Capsule endoscopy is a diagnostic procedure that helps the doctor to see the small intestine. You will be given a pill-sized video camera to swallow. This camera has its own light source and captures images of the small intestine as it passes through it. These photos are sent to a small recording device that you must wear on you. Your doctor will later have access to these photos and will be able to provide you with information about your small intestine. 

How should you prepare for Capsule Endoscopy?

  • An empty stomach allows for the best and safest examination, so don't eat or drink anything for around twelve hours before the examination, including water. Your doctor will provide details on when you should begin fasting.
  • Any medications you take, including iron, aspirin, bismuth sub-salicylate products, and other over-the-counter medications, should be disclosed to your doctor ahead of time. Prior to the test, you may have to change your normal dosage.
  • Discuss any drug allergies you may have, as well as any medical issues you may have, such as swallowing problems or heart or lung disease.
  • If you have a pacemaker or defibrillator or have had prior abdominal surgery or have a history of bowel obstructions or inflammatory bowel disease or adhesions, tell your doctor.
  • Prior to the test, your doctor can request that you do a bowel prep/cleansing.
