The Bravo pH test is a type of wireless esophageal pH monitoring that measures acid levels in your esophagus to help diagnose gastroesophageal reflux disease (GERD). During the test, a wireless capsule is attached to the wall of the esophagus during an upper endoscopy (a thin, flexible camera passed through your mouth into the esophagus). This is done to monitor acid reflux for the next 48-96 hours.
There are a few rules to follow when being monitored for the Bravo pH test– you can go on about your daily routine as you usually do. You have to be mindful of, e.g., restrictions on certain foods, drinks, medications, and avoiding MRI (for at least 30 days). Your care team will give you written instructions.
Why Diet Matters for Accurate Bravo pH Monitoring
Maintaining a regular diet is necessary to acquire accurate pH results so that acid levels can be monitored accordingly. Try to eat your usual meals at your usual times. If you skip meals, your stomach may not produce acid in its usual pattern, and the test may be less accurate. Skipping meals will not produce the required amount of acid, which may hinder the process of determining abnormal pH levels.
A Few Things to Keep in Mind for the Bravo pH Test
This list includes a set of simple steps that should be followed during the Bravo pH test:
- If your stomach is empty for long periods, the acid pattern is not the same as on a normal eating day, so it’s harder to interpret the test.
- Avoid frequent snacking between meals and do not chew gum. Lozenges, gum, and hard candies during the test can change how often acid reflux occurs and make the results harder to interpret.
- Avoid sipping acidic drinks between meals.
- Ask your doctor whether you should avoid sodas or drink your usual trigger drinks so your typical symptoms are captured.
- Make sure you track your meal times, such as the time you start eating or drinking till the time you stop. You will also need to record when you lie down and when symptoms occur.
Prepping for the pH Test
The process is not as scary as it may sound. In fact, the capsule is discharged through regular waste and won’t even feel like it’s there. Before the procedure, you’ll usually need to stop eating and drinking for several hours and follow your doctor’s instructions about acid-reducing medications.
During the monitoring period, eat your usual meals, avoid snacking, and follow the written instructions you’re given. If you skip meals, your stomach may not produce acid in its usual pattern and the test can be harder to interpret.
Do not start or stop acid-reducing medications or antacids unless your doctor tells you. Most of your regular medicines can be taken as usual, but always follow the specific medication list your gastroenterologist gives you.
To Sum It Up
The Bravo pH test is a simple and effective way to evaluate acid reflux, and following your daily eating habits helps in getting accurate results. By avoiding unnecessary snacking and following a few simple steps, you can help your practitioner learn more about your digestive system.
The capsule will detach on its own and pass out in your stool after several days. Most people either don’t feel it or only notice a mild sensation, especially when swallowing during the first day or two.
