Esophageal pH Assessment - 48 Hour Study
If you have symptoms of heartburn or acid reflux, your physician may want to determine the amount of acid (the pH) that is getting into your esophagus from your stomach. The Bravo capsule is clipped to the lining of your esophagus using a special device that is passed through your nose or mouth. The Bravo capsule will detach from your esophagus normally within five to 14 days and be passed out of your body during a bowel movement. The pH information is transmitted by radio waves from the capsule to a special receiver you will be asked to wear. You wear the receiver in a pouch that has a strap that goes around your waist or neck.
