Medical conditions that increase the risk for GERD include hiatal hernia, scleroderma, and Zollinger-Ellison syndrome.

增加GERD风险包括食管疝、硬皮与佐林格-埃利森综合征（胃素瘤）。

In hiatal hernia, the stomach and lower part of the esophagus slide up through the esophageal hiatus, which is an orifice in the diaphragm, and this decreases the pressure of the lower esophageal sphincter.

在食管疝中，胃和食管下部通过食管（是膈膜中一个）向上滑动（进入胸腔），降低了食管下括约肌压力。
