Answer

The postulated mechanism by which delayed gastric emptying may cause GERD is an increase in the gastric contents resulting in increased intragastric pressure and, ultimately, increased pressure against the lower esophageal sphincter. This pressure eventually defeats the LES and leads to reflux. However, objective studies have produced conflicting data regarding the role of delayed gastric emptying in the pathogenesis of GERD.
