• Abstract: RESUME INTRODUCTION Bariatric surgery and weight-loss medications are effective strategies for combating obesity, but they often result in significant skin changes due to rapid weight loss. The physiological inability of the skin to retract leads to issues such as skin laxity and redundant folds, affecting both physical and psychological well-being. Nutritional deficiencies and hormonal imbalances further complicate skin health post-weight loss. OBJETIVE To comprehensively review and analyze the skin changes that occur following bariatric surgery and the use of weight-loss medications, exploring the physiological, nutritional, and therapeutic aspects of managing these dermatological consequences. METHODS This is a narrative review which included studies in the MEDLINE – PubMed (National Library of Medicine, National Institutes of Health), COCHRANE, EMBASE and Google Scholar databases, using as descriptors: “Bariatric surgery” AND “Weight-loss medications” OR “Skin elasticity” OR “Excess skin” AND “Body contouring” in the last 5 years. RESULTS AND DISCUSSION Most patients experience significant skin laxity, particularly in the abdomen, arms, and thighs, with more severe changes observed in those undergoing rapid weight loss from bariatric surgery compared to those using weight-loss medications. Nutritional deficiencies and protein insufficiency exacerbate these changes, affecting collagen production and skin elasticity. Surgical and non-surgical interventions, such as body contouring, offer solutions, but their efficacy depends on patient factors such as age, genetics, and overall health. CONCLUSION Managing post-bariatric skin changes requires a multidisciplinary approach involving nutrition, hormonal balance, and tailored treatment strategies. While surgical options provide effective results for severe cases, early intervention and proper nutritional support can improve skin recovery and patient quality of life. Further research is needed to enhance non-surgical approaches and better address the psychological impact of these dermatological changes.
