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
