Bravo pH monitoring is an advanced test for monitoring esophageal acidity levels over a period of 48 to 96 hours, aimed at diagnosing gastroesophageal reflux disease (GERD). During endoscopy, a small capsule is attached to the wall of the esophagus, which transmits data wirelessly to a portable device carried by the patient.
The test enables precise monitoring of esophageal acidity during normal daily activities, including eating and sleeping, thus providing a reliable picture of the relationship between symptoms such as heartburn or chest pain and acid reflux from the stomach. The capsule detaches on its own after a few days and exits the body naturally.
