The Methodist Hospital Reflux Center & G.I. Physiology Lab is dedicated to aiding in the diagnosis and treatment of gastro-esophageal reflux disease (GERD) and gastrointestinal motility disorders. Since opening in 1998, we have strived to provide state-of-the art technology and testing strategies that can aid in the evaluation of this disease.

Physiology Lab and the Clinical Service Chief of Gastroenterology at The Methodist Hospital. She holds a dual appointment and is a Clinical Associate Professor of Medicine at Baylor College of Medicine and Weill Medical College of Cornell University.

Dr. Ergun has focused her research interests on the extra-esophageal complications of gastro-esophageal reflux disease, specifically supra-esophageal manifestations including reflux laryngitis and chronic cough.

Dr. Ergun is building on Methodist's reputation for cutting-edge science, state-of-the-art technology and long-standing commitment to superior patient care.

What We Do

Our state-of-the art laboratory offers a broad range of physiological tests. Our services offer comprehensive testing in all aspects of GERD as well as other motor disorders of the gastrointestinal tract. Our services include ambulatory esophageal pH (reflux) testing and motility testing of the oropharynx, esophagus, stomach, small intestine and rectum. These tests can be used to diagnose and manage gastro-esophageal reflux diseases, including typical symptoms such as heartburn or atypical manifestations such as chest pain unrelated to the heart, pulmonary and ear, nose, and throat (ENT) complaints. Our testing can also help evaluate problems outside of reflux, such as constipation or fecal incontinence.

Defining Gastro-esophageal Reflux Disease (GERD)

Gastro-esophageal Reflux Disease (GERD) is a condition in which stomach contents backflow, or reflux, into the esophagus. Stomach contents contain acid, bile and enzymes normally used to digest food, and all stomach contents can be very irritating to the lining of the esophagus. Heartburn commonly results. Most people describe heartburn as a feeling of discomfort behind the breastbone that is burning in nature. In some, this feeling can move up toward the neck and into the back of the throat. The sour taste, burning and pressure symptoms are often worse after eating and may be especially profound after eating potentially irritating foods such as spicy meals.

Stomach contents commonly reflux into the esophagus, but can also reflux from the esophagus into the back of the throat or the airway. This has been referred to as laryngopharyngeal reflux disease and can cause a bad taste in the mouth, loss of tooth enamel, chronic sore throat, hoarseness, choking, cough or wheezing, especially if stomach contents are aspirated or inhaled.

How to Receive Care

Individuals experiencing symptoms of reflux disease or other gastrointestinal motility disorders may be referred to the Reflux Center & GI Physiology Lab by their physician (Internal Medicine, Gastroenterology, ENT, Pulmonary, Surgery, or Family Physicians) for diagnostic testing.
