Motility Capsule at the Digestive Health Center
The motility capsule procedure is a single-use, ingestible capsule that measures pH, transit time, and
temperature as it passes through the entire GI tract. As the motility capsule travels through your digestive tract,
it collects data and sends it to a wireless data receiver, worn on a belt/lanyard. After five days, you return the
data receiver to the Digestive Health Center. The data is then downloaded to a computer giving your doctor
information to evaluate your stomach, small bowel and colon. The capsule will pass out of your body in a bowel
movement. You do not need to save the capsule.
