Mayo's experience helps doctors recognize hiatal hernias or other possible causes of your symptoms. Diagnosis of a hiatal hernia begins with a thorough review of your medical history and a physical exam. Mayo Clinic offers all standard diagnostic tests for hiatal hernia, including esophagography, endoscopy and manometry.

For people with symptoms of gastroesophageal reflux disease (GERD), Mayo Clinic offers a comprehensive evaluation to diagnose your condition, including pH capsule testing and 24-hour impedance pH testing.

During 24-hour impedance pH testing, your doctor places a thin, flexible catheter with an acid-sensitive and fluid-sensitive tip through your nose into your esophagus. Over the course of 24 hours, the catheter records the flow of liquid from your stomach into your esophagus.

This test has the advantage of measuring both acid and nonacid reflux and is typically used with people on maximal therapy for reflux. The results can help doctors design a course of treatment for you.

Results for all tests are typically available on the same day or within 24 hours. Efficient testing helps the team quickly arrive at a diagnosis, so your treatment can begin as soon as possible.
