About Non-Erosive Gastroesophageal Reflux Disease

Non-Erosive GERD is the largest category of GERD and is characterized by reflux-related symptoms in the absence of esophageal mucosal erosions. There are over 65 million U.S. patients living with GERD, and it is estimated that approximately 70% of this population have Non-Erosive GERD. Symptoms of Non-Erosive GERD may impact overall quality of life and can include episodic heartburn, especially at night, regurgitation, problems swallowing, and chest pain.

About Erosive GERD 

Erosive GERD, also referred to as Erosive Esophagitis (EE), is a subtype of gastroesophageal reflux disease (GERD) characterized by erosions in the gastric mucosa caused by acidic reflux of stomach contents into the esophagus. There are estimated to be over 65 million individuals with GERD in the U.S., of which approximately 30% have Erosive GERD. In addition to experiencing troubling heartburn symptoms, patients with inadequately treated Erosive GERD may progress to more severe diseases including Barrett’s esophagus and esophageal cancer.
