Acid reflux is a chronic digestive condition that can cause burning pain in the chest, regurgitation, and stomach pain. The condition is caused by stomach acid or bile moving up into the food pipe and irritating the lining.
Esophageal pH Testing
An esophageal pH test is performed using a small piece of equipment inserted through the nostril and lower into the esophagus. The equipment may be wireless or require you to wear a small cord. The wireless device can be inserted into the esophagus using an endoscope.
This device will be recording and transmitting your pH levels for 24 to 48 hours. It will also be able to track your symptoms and whether or not they change after you eat or lie down (which is common with acid reflux). You will be encouraged to partake in most of your regular activities while wearing the device in order to provide your physician with accurate information.
