What is GERD?

    Last Updated: October 13, 2024

    GERD is a chronic condition characterized by the backflow (or reflux) of stomach contents into the esophagus and throat through a dysfunctional esophageal sphincter. Up to 1 out of 6 people are affected globally, but the prevalence varies widely between regions. Though it isn’t life-threatening, it does have a substantial negative impact on quality of life, and if left untreated, may increase the risk of esophageal cancer. The causes and disease progression of GERD aren’t completely understood, but it can be managed or treated with lifestyle modifications, drugs, and surgery.[1][2]
