Introduction
The Bravo Wireless Capsule pH Monitoring is a modern, minimally invasive test designed to measure acid levels in the esophagus over 48 or 96 hours. This procedure is crucial for diagnosing gastroesophageal reflux disease (GERD) and assessing the severity of acid reflux symptoms. At Gastrointestinal Medicine Associates, we utilize the Bravo system to provide accurate, comfortable monitoring without the discomfort associated with traditional catheter-based pH testing.
Why It's Important:
The Bravo pH test plays an essential role in diagnosing acid reflux and GERD by measuring the frequency and severity of acid exposure in the esophagus. This information is key to creating an effective treatment plan for conditions such as heartburn, esophageal reflux, and other GERD-related symptoms. The Bravo system is also useful in evaluating the effectiveness of current GERD treatments and medications.
How to Prepare for Bravo pH Monitoring:
- Dietary and Medication Instructions:
- You may be asked to stop taking acid-reducing medications, such as proton pump inhibitors or H2 blockers, for several days before the procedure to ensure accurate results.
- Follow your usual diet during the monitoring period to get the most reliable data.
Before the Procedure:
- During an upper endoscopy, a small capsule about the size of a gel cap is placed on the lining of your esophagus.
- This capsule wirelessly transmits pH data to a small receiver that you wear or carry for 48 or 96 hours.
- The procedure is quick and painless, allowing you to return to your regular activities afterward.
What to Expect During the Monitoring Period:
- Normal Activities: You can continue with your daily routine, including eating and drinking, during the monitoring period.
- Symptom Tracking: Keep a diary of symptoms, such as heartburn, chest pain, or acid regurgitation, and record meal times. This helps your doctor correlate pH levels with your symptoms.
The Procedure and Technology:
- The Bravo capsule is attached during an endoscopic procedure. Once placed on the esophagus, it wirelessly sends pH readings to the portable receiver, eliminating the need for a traditional nasal catheter.
- After the monitoring period, the Bravo capsule naturally detaches and passes through the digestive system, making retrieval unnecessary.
Recovery and Results:
- The Bravo capsule remains in place without causing discomfort during the test. You may resume normal activities, but avoid activities such as swimming that could interfere with the receiver.
- After the monitoring period, you will return the receiver to your doctor for analysis. The data will help create a tailored treatment plan based on your results.
- Side effects are rare, but if you experience chest pain or difficulty swallowing, contact your healthcare provider immediately.
When to Consider Bravo Wireless pH Monitoring:
- Persistent Symptoms: If you continue to experience heartburn, acid reflux, or chest pain despite using GERD medications, this test can help pinpoint the cause and guide treatment.
- Diagnosing GERD: This test is recommended for those experiencing GERD symptoms or considering surgical interventions for acid reflux.
- Post-treatment Evaluation: The Bravo pH test can also be used to evaluate how well GERD treatments or procedures have worked, especially if symptoms persist.
