Acid reflux is one of the most common digestive issues, and for many people, symptoms can be confusing, persistent, or difficult to diagnose. When traditional testing does not give clear answers, the Bravo pH Probe Study offers a highly accurate, comfortable way to measure acid levels in the esophagus and pinpoint the cause of chronic reflux symptoms.

At Granite State Gastroenterology, serving patients in Bedford, NH and Londonderry, NH, this test is an important tool for diagnosing gastroesophageal reflux disease (GERD) and guiding effective treatment.

What Is a Bravo pH Probe Study?

The Bravo pH Probe Study is a minimally invasive test that measures how often acid flows from your stomach into your esophagus over a 48- to 96-hour period. Instead of using a nasal catheter like older pH tests, the Bravo system uses a tiny wireless capsule that attaches to the lining of your esophagus during an upper endoscopy.

This capsule continuously records acid levels and sends the information to a small receiver you carry with you. The capsule naturally falls off and passes through your digestive system after a few days.

What Does the Bravo Study Diagnose?

The Bravo pH study is primarily used to diagnose GERD, but it also helps evaluate:

  • Chronic heartburn
  • Unexplained chest pain
  • Regurgitation
  • Persistent cough or throat irritation
  • Symptoms not improving with reflux medication
  • Acid-related sleep disturbances

For patients in Bedford or Londonderry, NH who have ongoing reflux symptoms despite treatment, the Bravo test provides precise information that helps your gastroenterologist tailor your care.

What to Expect During the Procedure

1. Before the Test

Your care team will give you instructions on when to stop certain medications such as antacids, PPIs, or H2 blockers. This helps ensure accurate results.

2. During the Test

  • The capsule is placed during a quick upper endoscopy.
  • Most patients do not feel the capsule once it is in place.
  • You will be given a receiver and instructions on how to record symptoms, meals, and sleep.

3. After the Test

  • You go home the same day and resume most normal activities.
  • You will press buttons on the receiver to mark symptoms when they occur.
  • After 48–96 hours, you return the receiver for analysis.
  • The capsule naturally detaches and passes on its own.

There is no external tube, making this a more comfortable option than traditional testing.

Who Is the Bravo pH Probe Helpful For?

This study is ideal for individuals who:

  • Have frequent or severe acid reflux symptoms
  • Experience symptoms unresponsive to standard medications
  • Are being evaluated for anti-reflux surgery
