Test Senses More Than Just Acid in Reflux Patients
Ohio State University physicians are putting new technology to use to diagnose complicated reflux disorders that don't respond to anti-acid medications.
Though many gastroesophageal reflux disease cases can be controlled by drugs that suppress acid, some reflux sufferers find no relief from over-the-counter or prescription medicines because acid isn't a factor in their disorder. But before this technology became available for clinical uses, such cases were difficult to diagnose.
The gold standard for detecting acid reflux is pH monitoring, a test that measures how often and for how long stomach acid enters the esophagus. This monitoring can now be combined with the use of impedance technology, which uses electrical currents to sense the movement of stomach contents upward into the esophagus.
"For a long time, we have
