**Abstract**

The prevalence of obesity has increased globally. Management of obesity consists of medical and surgical interventions. The results of bariatric surgery are consistently more significant than medical therapy. Importantly, bariatric surgery achieves durable weight loss in more patients than medical therapy. Moreover, studies have reported improvement in most obesity-related complications after bariatric surgery. Improvement or remission of type 2 diabetes mellitus, hypertension and dyslipidemia is noteworthy. Due to better outcomes, the indications of bariatric surgery are expanding. In conclusion, bariatric surgery is a cost-effective and safer alternative for morbidly obese patients who fail to respond to non-surgical treatments. Some studies have raised concerns about the worsening of mental health problems after bariatric surgerys. It requires careful management of high-risk patients and further research.
