The Bravo capsule is used to further assess GERD. During an EGD, a small capsule may be temporarily affixed to the lining of the lower esophagus. There, it is set to wirelessly transmit the pH (level of acidity) of the lower esophagus to a recording device that’s worn outside the body and, later, returned to the office.
The Bravo capsule detaches from the lower esophagus on its own and passes through the GI tract and into the toilet.
