What kind of doctor provides Bravo Ph Study?
A gastroenterologist usually performs a Bravo pH study. Your primary care doctor often orders the test first and then refers you to this specialist. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What it is
A Bravo pH study measures acid in your esophagus, the tube that carries food from your mouth to your stomach. The doctor places a small capsule, about the size of a gel cap, into the esophagus lining during a short procedure. Its tiny sensor sends pH readings to a receiver you carry, usually for about 48 hours. The capsule then detaches and passes naturally through your digestive system.
Why a doctor might recommend it
Doctors use this test to check for gastroesophageal reflux disease, or GERD, when stomach acid backs up into the esophagus. Your doctor might recommend it if heartburn medicines have not worked, before reflux surgery, or when symptoms are unclear.
How to prepare
- Ask which medicines to stop, especially antacids and acid reducers, and when.
- Do not eat or drink for the hours your doctor tells you, often starting the night before.
- Tell your doctor about all medicines, including blood thinners, and any allergies.
- Arrange a ride home if you will receive medicine to help you relax.
- Ask what foods to avoid on the day the capsule is placed.
What happens during it
You will lie on your side while the doctor passes a thin, flexible tube with a camera through your mouth into your esophagus. The doctor attaches the capsule with a small clip and removes the tube. The procedure takes about 15 to 30 minutes. You will get the receiver and instructions on when to press its buttons, such as when you eat or have symptoms.
Recovery
Most people go home the same day and return to normal activities quickly. You might have a mild sore throat or feel a small lump when swallowing for a day or two. You can usually eat normally, though your doctor may ask you to avoid hard or crunchy foods briefly. You will return the receiver after the test.
Risks and side effects
The study is very safe, but rarely the capsule can cause chest pain, bleeding, or a tear in the esophagus. Call your doctor if you have severe pain, trouble swallowing, or vomiting blood.
Who performs it
A gastroenterologist most often places the capsule, though a general surgeon sometimes does it. The test is done in a hospital endoscopy suite or outpatient procedure center.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance. A concierge doctor usually charges more and often works alongside insurance. Either can be a helpful first stop for heartburn and reflux. If symptoms do not improve or a Bravo pH study is needed, they will refer you to a gastroenterologist.
Common questions
Does the capsule need to be removed?
No. It detaches on its own after several days and passes naturally in your bowel movements.
Can I have an MRI with the capsule in place?
Not for about 30 days after placement, because it contains a small magnetic part. Tell any doctor ordering an MRI that you had the capsule. Tell any doctor ordering an MRI that you have the capsule.
Will I feel the capsule?
Some people feel a lump or mild scratch when swallowing for the first day or two. This usually fades.
How long does the test last?
The capsule typically records for about 48 hours.
