The first explanation for the cause of this condition is that because of the incompetence of the Lower Esophageal Sphincter (LES) acidic contents of the stomach are allowed up into the esophagus, which results in a burning sensation. The LES is a valve that is found at the lower end of the esophagus and separates it from the stomach and its contents but when this valve becomes dysfunctional, it allows the acidic content of the stomach to be regurgitated into the esophagus.
