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

GERD险的疾病包括食管裂孔疝、硬皮病与佐林格-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.

在食管裂孔疝，胃和食管下部通过食管裂孔（这是的一个孔）向上滑动（进入胸腔），这降低了食管下括约肌的压力。
