Obesity has been recognized as a health problem worldwide because of its negative effects. Obesity has increased the incidence rate of some diseases. Among them, gastroesophageal reflux disease (GERD) is more typical. Recently, GERD has become more and more popular among obese people. Scholars have begun to pay attention to the association between obesity and GERD. Some literatures and data point out that obesity is one of the important factors related to GERD. In the face of these problems, surgical and non-surgical treatment can be used, but recently, surgical treatment, especially weight loss surgery, has become more and more popular. In order to provide reference for clinicians and patients, this paper reviews the relationship between obesity and GERD, and the treatment methods and development of obesity complicated with GERD in recent years.
