The article presents a comparison between two widely used bariatric surgeries, Roux-en-Y Gastric Bypass (RYGB) and Vertical Gastrectomy (GV), highlighting their efficacies, complications, and considerations for obese patients. Initially, the prevalence of obesity and the importance of bariatric surgery in improving metabolic problems associated with obesity are discussed. The study’s methodology consisted of a comprehensive literature review, searching for articles on various platforms such as PubMed, SciELO, and UpToDate, regarding the surgical procedures Roux-en-Y Gastric Bypass (RYGB) and Vertical Gastrectomy (GV) in bariatric surgeries. GV has emerged as the most common bariatric surgery in recent years due to its simplicity and efficacy, while RYGB, although effective in long-term weight loss, presents greater complexity and associated risks. It is concluded that discussion with healthcare professionals is essential for an informed decision on the most suitable type of bariatric surgery, emphasizing that the choice between them should consider the individual needs of each patient, health, and weight loss goals.
