The BRAVO pH capsule measures and monitors gastroesophageal acid levels (pH). BRAVO is used to evaluate how much and often you experience gastroesophageal reflux during a normal day. Gastroesophageal reflux can occur for a variety of reasons, including: food triggers (alcohol, chocolate, coffee, spicy or fatty meals), obesity, smoking and/or stomach abnormalities such as a hiatal hernia, to name a few.
An upper GI endoscopic procedure, BRAVO involves placing a capsule into the esophagus above the lower esophageal sphincter (LES). After the capsule is positioned, it is applied by suction to the esophageal wall. This action secures the capsule into place. You will then wear a small monitor that clips to your clothing for a minimum of 48 hours, allowing the capsule to wirelessly transmit information.
