What is esophageal impedance testing?
Esophageal impedance testing, also known as esophageal 24-hour impedance reflux monitoring, is a 24-hour test that monitors and measures the amount of acidic and non-acidic reflux that enters your esophagus from your stomach over the period of time. This test helps your provider determine if the reflux you are having is the cause of any symptoms you might be experiencing, such as heartburn, cough, sore throat, or regurgitation. This exam is most commonly performed on patients who are candidates for possible endoscopic or surgical anti-reflux repair. Esophageal impedance testing also helps GI Alliance of Illinois providers diagnose many symptoms that patients are experiencing, including:
- Regurgitation
- Chest pain/cough
- Reflux refractory to PPI
- GERD
- Acid Reflux
- Recurring pneumonia
- Laryngopharyngeal Reflux
If you are having any of the above symptoms and feel that esophageal 24-hour impedance reflux monitoring might be beneficial for you, contact a GI Alliance of Illinois provider in your area.
How is an esophageal impedance test performed?
During an esophageal impedance test, a small catheter will be placed through your nasal passage, and into your esophagus by swallowing drinks of water. The external catheter will be attached to a data recorder. This device will pass on any information it records to a computer that will store and process the data. During the 24-hour period, you should be able to complete your normal daily activities like eating, breathing, and talking without interference from the catheter.
Although most patients can complete the test without any discomfort, you may experience slight discomfort in the back of the throat during the monitoring period. To learn more about the esophageal impedance test or to schedule this exam, contact a GI Alliance of Illinois location near you.
