What do I need to know about a capsule endoscopy?
Capsule endoscopy is a procedure to take pictures of the inside of your small bowel (intestine). The pictures may show if you have growths, swelling, or bleeding in your intestine. You may need this procedure if you have symptoms such as blood in your bowel movements or chronic stomach pain.
How do I prepare for a capsule endoscopy?
You may need medicines to help clean out your intestines before the procedure. Ask about directions for eating and drinking before your procedure. You may need to stop eating or drinking 12 hours before the procedure. Do not smoke for 24 hours before the procedure. Tell your healthcare provider what medicines you take and ask him or her when they should be stopped before the procedure.
What will happen during a capsule endoscopy?
- You will be given the pill-sized capsule endoscope to swallow. The capsule will travel through your body the same way your food does and take 2 to 3 pictures every second. Small sensors will be taped to your abdomen and connected to a recorder. The sensors send the pictures of your small bowel to the recorder. The recorder will be attached to a belt that you wear during the procedure.
- You can go home after you swallow the capsule and have the sensors placed. Your healthcare provider will tell you when to return. Do not bathe or go in hot tubes or pools. Do not do vigorous physical activity or lift anything heavy.
- Do not eat or drink for at least 2 hours after you swallow the capsule. After 2 hours, you may drink clear liquids like water or juice. You can have a light snack and take your medicines after 4 hours. The procedure will be complete in 8 hours. You will be able to work or do your daily activities during the procedure.
What will happen after a capsule endoscopy?
The capsule usually comes out in your bowel movement within 3 days, but may take longer. It is okay to flush the recorder. You can remove the sensors. Return the recorder to your healthcare provider as directed. A healthcare provider will view the pictures of your small bowel and look for any problems.
What are the risks of a capsule endoscopy?
You may have stomach pain during your procedure. The capsule may not come out in your bowel movement. The pictures taken by the capsule may not be clear.
