A patient’s story
Albert, 42, had ongoing heartburn despite medication. His gastroscopy looked normal, yet symptoms persisted. To understand what was really happening, his specialist recommended a BRAVO pH capsule test. The results finally confirmed abnormal acid exposure and allowed a clear treatment plan to move forward.
What is the BRAVO pH capsule?
The BRAVO pH capsule is a small, wireless device used to measure acid exposure in the oesophagus over 48 to 96 hours. It helps diagnose gastro-oesophageal reflux disease (GERD), especially when symptoms are unclear or gastroscopy appears normal.
It is often performed during a gastroscopy for accuracy and convenience.
Why is the BRAVO pH test used?
The BRAVO pH capsule helps:
Confirm or exclude acid reflux
Assess severity of GERD
Evaluate symptoms not responding to medication
Distinguish GERD from functional heartburn
Guide decisions about long-term medication or procedures
How the combined gastroscopy and BRAVO procedure works
During gastroscopy:
A thin endoscope examines the oesophagus, stomach and duodenum
The BRAVO capsule is gently attached to the oesophageal lining
The capsule transmits pH data wirelessly to a small receiver
You go home the same day and continue normal daily activities while acid levels are recorded.
What does the BRAVO capsule measure?
The capsule records:
How often acid reflux occurs
How long acid stays in the oesophagus
Whether symptoms correlate with acid exposure
This provides a far more realistic picture than short, in-hospital tests.
What happens after the test?
The capsule naturally falls off within a few days
It passes harmlessly through the digestive system
Data is analysed to guide personalised treatment
Is the BRAVO pH capsule safe?
Yes. It is well tolerated and minimally invasive.
Temporary side effects may include:
Mild chest discomfort
Bloating
Sensation of something in the throat
These usually settle quickly.
Who should consider a BRAVO pH test?
You may benefit if you have:
Persistent heartburn despite treatment
Normal gastroscopy but ongoing symptoms
Symptoms before reflux surgery or TIF
Suspected non-acid or functional heartburn
