Abstract : Obesity is seen as a chronic condition that may be managed by changing one's lifestyle, using medication, or having weight loss surgery. In Saudi Arabia, there has been a substantial increase in the number of people getting bariatric surgery. Although the benefits and drawbacks of surgery are well documented, it is still unknown if weight loss following surgery will last. Our goal was to evaluate the results of bariatric surgery. For pertinent information, PubMed, Web of Science, Science Direct, Cochrane Library, and Google Scholar were scoured in-depth. The Rayyan QRCI was employed throughout this thorough procedure. Our study article included 12 studies, in which the consequences and outcomes of bariatric surgery was explained. The main parameters like age, sex, type of surgery and body mass index were obtained. The clinical studies were required to determine the benefits and bad consequences related to bariatric surgery in Saudi Arabia. In order for bariatric surgery to be effective, sustaining weight reduction and reducing weight gain must be accomplished. Before and after surgery, factors including gender and the kind of surgery should be taken into account, with a focus on the need for long-term follow-up to ensure the best benefits and the worst outcomes from this intervention.
