How should I prepare for an esophageal pH test?

Do not eat or drink anything after midnight on the evening before an esophageal pH study, which measures how much stomach acid backs up into the food pipe. (If you are diabetic, please discuss this requirement with your primary care doctor.) You may, however, take scheduled medications with small sips of water up until two hours before the study. You should also refrain from taking any antacids (Zantac, Prevacid, Prilosec, etc.) for the 72 hours immediately prior to the procedure, unless advised otherwise by your doctor.
