Gastroesophageal reflux disease (GERD) refers to reflux of the gastric content into the esophagus, leading to esophagitis, reflux symptoms impairing the quality of life, or long-term complications [1]. GERD is one of the most common disorders seen by primary care providers and gastroenterologists in the United States as well as in Europe [2].
