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. GERD is a chronic condition, which means there is no cure. Once it begins, it usually is life-long. If there is injury to the lining of the esophagus (esophagitis), this also is a chronic condition. Eating. Eat your regular meals at the usual times and eat the way you normally do. If you do not eat during the monitoring period, your stomach will not produce acid as usual, and the test results will not be accurate. Eat foods that tend to increase your symptoms (without making yourself miserable, of course). You may drink as much plain water as you want.
Keep track of your symptoms so that you can help the doctor determine what is wrong. Be sure to take note of whether your symptoms occur in the morning, at night, or throughout the day. Try to keep track of whether your symptoms occur when you eat certain foods. In most cases, you can resume your normal diet and regular medications immediately following the exam. The barium may cause your stools to be gray or white and you may feel constipated for two to three days following the procedure. Drink extra fluids if needed to help your body resume a regular schedule.
