• Abstract: Obesity is a worldwide epidemic affecting millions of people. Bariatric surgery is one method for tackling morbid obesity in people with a body mass index greater than 30 kg/m2. Vertical Sleeve Gastrectomy and Roux-en-Y gastric bypass (RYGB) are surgical techniques currently used in bariatric surgeries. It is critical to assess the benefits and drawbacks of each surgical technique to select the best option for each patient. Sleeve gastrectomy and RYGB were compared regarding patients' age, gender, ethnicity, weight loss, weight gain, early post-surgical complications, systemic hypertension, diabetes, and dyslipidemia. Studies about Sleeve and Gastric Bypass bariatric surgeries in adults who experienced weight loss and were published in the last five years were selected for a systematic review following the PRISMA guidelines. Non-human studies, nonrandomized studies, studies on gastric banding, and studies that did not address the topic or were irrelevant to the work were excluded. The mean age of the 45 studies chosen was 42 years old, with most patients female (63.2%). Despite a higher risk of post-surgical complications, RYGB was more effective than sleeve gastrectomy for systemic arterial hypertension, diabetes, dyslipidemia, and weight loss. Setting weight loss goals should be a collaborative effort between the doctor and the patient, and the limitations, risks, and benefits of bariatric surgery should be discussed before.
