What is Ph monitoring?
It is a procedure designed to measure the Ph level of stomach acids in patients with GERD.
How is it performed?
Using an endoscope, the gastroenterologist is able to attach a small capsule to the esophageal mucosa. The capsule then transmits Ph data to an external receiver worn by the patient.
How long does it monitor?
It monitors for approximately 48 hours.
What do I need to do?
You will be asked to record certain events such as when and what you ate. An endonurse will also instruct you on what other information needs to be recorded.
What happens after 48 hours?
You return the receiver to the endoscopy unit.
What happens to the capsule?
The capsule does not have to be removed. It will detach from the esophageal mucosa and pass on its own.
