Background: While laparoscopic sleeve gastrectomy (LSG), a restrictive procedure used as a first step for patients with severe obesity, laparoscopic Roux-en-Y gastric bypass (LRYGB) is not, it is a hybrid method that combines gastric restriction with gastrectomy and malabsorption LRYGB is a hybrid procedure that combines gastric restriction with gastrectomy and malabsorption. Due of its greater effectiveness when compared to very restricted methods, it has emerged as the most popular and accepted method. Before undergoing a mal-absorptive procedure, patients with excessive obesity (body mass index (BMI) >50 kg/m2) first undergo the restricted LSG approach, Similar outcomes have been obtained from both bariatric surgical techniques in terms of reduced cardiovascular risk, weight loss, enhanced glucose metabolism, significant changes in serum lipid concentrations, hypertension, and nutritional status .

The only long-term, reliable therapeutic option for obese individuals who have a high cardiovascular mortality rate is bariatric surgery

This study compared the effects of gastric bypass and laparoscopic sleeve gastrectomy, two bariatric surgical techniques, on body weight and common related comorbidities in obese people.
