Effect of Continuous Positive Airway Pressure (CPAP) on Lower Esophageal Sphincter Pressure in Morbidly Obese Patients

Completed

Conditions studied: Sleep Apnea, Gastroesophageal Reflux Disease

In brief

This trial is enrolling patients who are already being seen at OHSU weight loss clinic or have been referred for clinical reasons by their physician to the OHSU weight loss clinic and are going to have a esophageal manometry that would be paid for by their insurance company for clinical reasons. In patients undergoing weight loss surgery investigators plan to study the effect of continuous positive airway pressure during a esophageal manometry.
