The Wireless pH Study is a state-of-the-art diagnostic procedure used to measure acid levels in the esophagus, helping doctors assess and monitor gastroesophageal reflux disease (GERD) and other digestive conditions. Many patients who receive this test are doing so to confirm or rule out a GERD diagnosis. Unlike traditional methods, this study uses a small, capsule-like device attached to the esophagus, which wirelessly transmits pH data, providing a comfortable, minimally invasive experience for patients.
A Wireless pH Study is primarily used to detect acid reflux and GERD symptoms like heartburn, chest pain, and regurgitation. It provides valuable information on the frequency, duration, and severity of acid exposure in the esophagus, allowing healthcare providers to create a targeted treatment plan.
Doctors recommend a Wireless pH Study when patients have persistent acid reflux symptoms despite treatment, or when diagnosing GERD and determining its severity. This study is also beneficial for evaluating the effectiveness of ongoing GERD treatments or preoperative assessments for GERD-related surgeries.

There are several specific instructions that all patients should follow prior to starting a wireless pH study, including:
Do not eat or drink for a period of 6 hours before your pH test.
Review all current medications you are taking with your doctor. Your doctor may ask you to temporarily stop certain medications that affect stomach acid.
Tell your gastroenterologist of any known conditions or allergies that you have
Many medications can affect the results from a wireless pH study, particularly those that you may be taking to manage acid reflux symptoms. Be sure to discuss all these medications with your doctor, and to precisely follow their instructions for the entirety of the pH study.
The entire procedure is quite simple, and even allows patients to return home while the test is still being conducted.
In the traditional version of this study, you would need to have a probe inserted through your nose that would then be gently guided down to the lower end of your esophagus. This probe would need to remain in place for a full 24 hours, which tends to cause patients a significant amount of discomfort.
To avoid such an issue, our gastroenterologists utilize a small, wireless device instead. This device is contained inside a capsule and is carefully placed at the lower end of the esophagus by your gastroenterologist. Over a short period of about 48 hours the capsule will dissolve, and the device will be naturally expelled from your body.
Once a method is selected and the probe is in place, the device will begin transmitting information to a monitor that will be able to tell you when reflux symptoms begin. The monitor is conveniently situated on a belt that can be worn around the waist so as not to restrict the patient’s mobility.
Patients are advised to carry on with their normal daily routine while the probe is in place. Maintaining regular activities and eating times is essential for the study, because this will allow for more accurate results that can better explain the cause of the person’s reflux symptoms.
Since the Wireless pH Study is non-invasive, there is minimal to no recovery time. Patients can return to regular activities immediately after the capsule placement. Minor throat discomfort is possible but typically subsides quickly.
While the Wireless pH Study is safe, rare risks may include minor throat irritation or discomfort. In very rare cases, the capsule may not detach naturally and could require endoscopic removal. Your GI specialist will discuss all potential risks with you before the procedure.
The Wireless pH Study offers a clear and precise view of your esophageal acid levels, providing critical insights for effective management of GERD and other digestive conditions. At GI Solutions, we are dedicated to bringing you the latest in diagnostic technology to ensure personalized and comfortable care for every patient.
