Esophageal pH Monitoring
in NYC

A woman experiencing esophageal pain in her chest, she is with a doctor who is diagnosing and monitoring the issues on a tablet device, she is a prime candidate for esophageal pH monitoring.

What is pH monitoring?

pH monitoring, also known as esophageal pH monitoring, is the measuring of acid from the stomach that is regurgitated into the esophagus, a frequent occurrence for patients that suffer from gastroesophageal reflux disease (GERD). In general, the pH of something refers to the measure of acidity or alkalinity within a solution. By evaluating the acidity levels that are backwashed into the esophagus, pH monitoring is useful in the diagnosis and treatment of GERD.

Why is pH monitoring performed?

In addition to helping classify acid reflux for diagnosis purposes, pH monitoring also assists in determining the effectiveness of certain medications used for the treatment of GERD. For patients that are experiencing chest pain, esophageal pH monitoring can help in the determination of the cause of the pain, whether it is a result of acid reflux or if it may be related to more severe problems such as cardiac disease.

Esophageal pH monitoring diagnosis

This tool is incredibly thin, about one-sixteenth of an inch wide, and is made of plastic. During the pH monitoring procedure, the catheter is inserted through a nostril and guided down the back of the throat into the esophagus, and the patient is then instructed to swallow. The catheter is able to detect levels of acid from the area just above the lower esophageal sphincter, which is the area that, when functioning properly, prevents stomach acid from refluxing into the esophagus. A reader is attached to the catheter in order to register the acidity levels over the course of one day.

To test for acid reflux, the catheter is required to stay in place for 24 hours. This means the patient will be sent home with the device in place. For the 24 hour time period that the device is in place, the patient will be able to eat, sleep, and resume their regular routine. During this time, your physician will instruct you to record all activities either through the use of a diary or directly on the recorder attached to the catheter. All meals, periods of sleep, and physical activity should be recorded. After the catheter is removed, the data detailing the course of your daily diet and activities will be graphed and correlated to the corresponding levels of present acidity.

Battery-operated pH monitoring capsule

Another method for pH monitoring is with the use of a battery-operated capsule. The capsule is inserted through the nostril with a catheter but is able to be linked to the esophagus, allowing the catheter to be removed directly after insertion. The capsule records the acidity levels for 2-3 days before detaching and passing through the stool. The biggest benefit of the capsule over the catheter is that it eliminates any discomfort associated with the catheter protruding from the nose.

Overall, there are very few side effects or complications associated with esophageal pH monitoring. The catheter may cause mild discomfort in the back of the throat, especially when swallowing. Overall, however, the catheter does not impede a patient’s ability to eat, sleep, or partake in physical activity.
