Gastroesophageal Pressure Gradients in Gastroesophageal Reflux Disease: Relations With Hiatal Hernia, Body Mass Index, and Esophageal Acid Exposure

Abstract

BMI predicts IGP, inspiratory GEPG, and expiratory IEP. Age predicts inspiratory IEP and GEPG. Presence of HH is predicted by IGP, GEPG, and BMI. GEPG is not associated with acid exposure.
