GLP-1 receptor agonists for weight loss, benefits and risks: A systematic review of the literature

Abstract

Introduction: Obesity is a chronic disease linked to numerous complications. Pharmacotherapy constitutes one of the therapeutic options by which people with obesity can achieve and maintain the desired weight.Objectives: to describe the mechanism of action of glucagon-1 receptor agonists (GLP-1RAs) and their effect on weight loss and long-term weight maintenance. Methods: an information search was conducted using biomedical databases to gather relevant evidence on the efficacy and safety of GLP-1RAs in weight management. Studies addressing both initial weight loss and long-term maintenance based on the use of GLP-1RAs were analyzed.Development: GLP-1RA therapy, initially developed to treat type 2 diabetes, has been shown to be effective in reducing body weight. Daily subcutaneous administration of liraglutide has been approved, and weekly subcutaneous administration of semaglutide is being investigated in phase III trials for the management of obesity. Conclusions: consideration of GLP-1 receptor agonists as a robust therapeutic option for the management of obesity in patients who have not responded adequately to other interventions is recommended. Their use should be personalized, carefully evaluating the benefit-risk ratio for each patient. It is crucial to continue research in this field to better understand the long-term effects of GLP-1 receptor agonists
