Gastroesophageal reflux disease, commonly referred to as GERD, is one of the most common disorders, and its incidence and prevalence have increased over the last two decades. GERD is characterized by the sensation of substernal burning caused by abnormal reflux of gastric contents backward up into the esophagus. GERD has two different manifestations, reflux esophagitis (RE) and non-erosive reflux disease (NERD), depending on the presence or absence of esophageal mucosal breaks. Symptoms of GERD are chronic and can significantly impair quality of life. Therefore, it has been regarded as a considerable health problem in most of the world. Recommendations for lifestyle modifications are based on the presumption that alcohol, tobacco, certain foods, body position, and obesity contribute to the dysfunction in the body’s defense system of antireflux.
