Have you gulped or guzzled water, only to find that it refluxes back up into your throat? What’s going on here?

“Water, in and of itself, does not cause reflux,” says Akram Alashari, MD, abdominal surgeon and critical care physician, Department of Surgery, College of Medicine, University of Florida

He continues, “Rather, reflux is caused by overfilling of the stomach. When someone drinks enough water to expand the stomach, the lower esophageal sphincter will allow the acidic medium of the stomach to reflux back into the esophagus.

“It is when the stomach contents reflux back when the symptoms of heartburn occur. So the mechanism of water causing reflux is by dilation of the stomach with secondary reflux.” water
