Introduction: Obesity, an easily diagnosed disease, is multifactorial, chronic, and difficult to manage. It has increased alarmingly and is now one of the main public health problems. It is associated with several comorbidities and poorer quality of life. Bariatric surgery is currently widely accepted and described in the literature as the most effective method for the treatment of obesity. Even though this is the best method, weight regain (WR) is also checked. In the literature, there are several parameters used to configure WR, and with that, several results are presented. Objective: This paper aims to review the parameters used to assess WR after bariatric surgery. Method: A bibliographic review of the last 5 years was carried out in the PubMed and Scielo virtual databases with the following keywords: bariatric surgery, obesity, and weight regain, in October and November 2019. Result: Lack of unanimity in the definition and parameters for WR is still a reason for further studies. And with that, the results are also presented in a varied way, depending on the parameter used. Conclusion: The subject is relatively new and there is a need for more studies to define and quantify the meaning of WR, to also improve the approach and management of the patient with weight regain. But there seems to be a tendency to adapt itself as a favorable response to surgical success when at least 50% excess weight loss (%EWL) and > 20% total weight loss is achieved, and that any regain should not be used. as a parameter to define it.
