Bravo Endoscopy
(Bravo pH Monitoring Test)
A Bravo endoscopy refers to an upper endoscopy procedure where a tiny wireless pH capsule (the Bravo capsule) is attached to the esophagus to measure acid reflux over time. The full name is Bravo pH monitoring.
What it’s used for
Doctors use it to diagnose conditions related to acid reflux, such as:
- Gastroesophageal Reflux Disease
- Chronic heartburn
- Unexplained chest pain
- Persistent cough or throat irritation related to reflux
- To evaluate patients before anti-reflux surgery
How the procedure works
- Upper endoscopy: A doctor inserts a thin flexible scope through your mouth to examine your esophagus and stomach.
- Capsule placement: A tiny capsule (about the size of a gel pill) is attached to the lining of your esophagus.
- Wireless monitoring: The capsule measures acid levels (pH) and sends the data wirelessly to a small receiver you wear on your belt or shoulder.
- Monitoring period: Usually 48–96 hours (2–4 days).
- Capsule falls off naturally: It detaches on its own and passes through your digestive system.
What you do during the test
You’ll typically:
- Carry the receiver
- Keep a diary of symptoms, meals, and sleep
- Press buttons on the receiver when symptoms occur
This helps doctors match acid spikes with your symptoms.
What it feels like
Most people:
- Are sedated during the endoscopy
- May feel a slight sensation when swallowing for a day or two
- Usually resume normal activities the same day
Advantages compared to older reflux tests
Compared to traditional catheter-based pH tests:
- No tube coming out of the nose
- More comfortable
- Allows more normal eating and activity
- Longer monitoring period
Possible side effects (uncommon)
- Temporary chest or throat discomfort
- Feeling like something is stuck when swallowing
- Very rarely the capsule may need removal
