What is Bravo® pH Monitoring and What Purpose Does It Serve?

Bravo® pH Monitoring is a test that measures and records the pH of your esophagus. The results help determine if you have gastroesophageal reflux disease (GERD), a condition where acid from the stomach moves back up to the esophagus. Left untreated, GERD can lead to serious medical problems. The test involves your doctor placing a tiny disposable capsule on the wall of your esophagus. The capsule continually monitors the pH in your esophagus for 48 to 96 hours and wirelessly sends the data to a receiver you wear on your belt. After the testing period, the capsule falls off and passes through your digestive tract. You likely won’t even know it. You take the receiver to your doctor and he or she will download the results and analyze the information to learn more about your condition.

How Should I Prepare for the Procedure and What Can I Expect?

Before starting the test, your doctor may provide you with specific dietary instructions and temporary adjustments to your over-the-counter and prescription medications. This is to ensure there is no interference with the data collection.

The day we start the test, your doctor will place the small, wireless capsule onto the wall of your esophagus. The capsule transmits data to the receiver based upon the symptoms you experience while eating or drinking, and when you are active or resting. Your doctor may tell you about dietary or medication restrictions during the monitoring period. Otherwise, you may resume your normal activities and diet.

The monitoring period generally lasts 48 hours, but it may vary depending upon your symptoms. The pH capsule will detach on its own and pass through your digestive tract within 7 to 10 days. After the monitoring is complete, you can go back to your normal activities and diet.

Your doctor will give you instructions on returning the data recorder. He or she will follow up with you to talk about the results and whether you should have additional tests or procedures.
