Abstract

There has been a sharp increase in the number of obese people worldwide thanks to modern prosperity in accordance with rapid industrialization and economic development. Recently, bariatric surgery has been applied actively to extremely obese patients (BMI>35 kg/m2) and presented as an alternative solution to provide not only weight loss but also a treatment for metabolic diseases such as diabetes mellitus, hypertension, and hyperlipidemia. Gastroesophageal reflux disease (GERD) is one of the most important diseases in morbidly obese patients, and many patients suffer from symptoms like epigastric pain, regurgitation, and dry cough. However, such symptoms are easy to be overlooked and studies on GERD are scarce in relation to bariatric surgery. In morbidly obese patients, high abdominal pressure leads to a pressure gradient between esophagus and stomach. This induces a hiatal hernia causing a greater likelihood of GERD. Many studies in regards to GERD were made after bariatric surgery (sleeve gastrectomy, Roux-en-Y gastric bypass, and gastric band), and various results have been presented. Studies should be carried out on pre-operative diagnosis of GERD, choice of operative method, and improvement of symptoms after the operation. Research is also needed upon bariatric operation in patients with uncontrolled GERD.
