When doing the gastroscopy, the doctor also tests for a great many things you had no clue about. One of these is your PH. When there are irregularities, you will be sent for the following:  The esophageal pH test is an outpatient procedure performed to measure the pH or amount of acid that flows into the esophagus from the stomach  during a 24-hour period.

The procedure is commonly used to help confirm the diagnosis of  GERD or to identify the cause of various symptoms, including:

Heartburn, primarily in patients who have had a normal endoscopy and who have failed medical treatment or may be considered as candidates for surgery

  • Uncommon symptoms of  GERD (gastroesophageal reflux disease), such as chest pain,  chronic cough,asthma, and other throat symptoms.

How this works:

The equipment used in the esophageal pH test consists of a small probe that is inserted through your nostril and positioned near the lower esophagus. The probe is plugged into a small unit (or monitor) worn on your belt or over your shoulder. A newer, wireless device may make monitoring the pH level easier: Instead of having to have a tube placed down your nose for 24 hours, your doctor will place a disposable capsule into the esophagus using an endoscope. The capsule then wirelessly transmits information for up to 48 hours to a receiver worn around the waist.

With the touch of a button on your monitor, it will record the following information:

  • The occurrence of symptoms
  • The times when you eat and lie down

A nurse will review the monitoring instructions with you.

Be careful with the monitor and keep it dry at all times.

This is not a pleasant test but I can assure you, you won’t die. It is uncomfortable, and you might get a little nauseous, but when its done, its done. Just a quick tug and its out and you can go on as usual.
