It is considered a disease of the developed countries, although it is rising in developing countries. This is due to the increasing presence of the associated risk factors such as obesity, smoking, and comorbidities. We aimed to review the literature reviewing the etiology of gastroesophageal reflux disease, risk factors, clinical presentation, diagnosis, and management of this disease. PubMed database was used for articles selection, gathered papers had underwent a thorough review. Gastroesophageal reflux disease (GERD) is a common disease in this millennia, owing to numerous factors including comorbidities, use of medications, and sedentary lifestyle.
