How Much Weight-loss Occurs after LSG?
Several studies have documented excellent weight-loss up to three years after LSG.3-6 In higher BMI patients who undergo LSG as a first stage procedure, the average patient will lose 40 – 50 percent of their excess weight in the first two years after the procedure.4 This typically equates to about 125 pounds of weight-loss for patients with a BMI greater than 60. Patients with lower BMI’s who undergo LSG will lose a larger proportion of their excess weight (60 – 80 percent) within three years of the surgery. 3, 5, 6 Weight-loss after LSG has been directly compared to Laparoscopic Adjustable Gastric Banding (LAGB). In a randomized trial comparing LSG to LAGB, LSG resulted in better weight-loss at three years (66 percent versus 48 percent excess weight-loss). Additionally, more than 75 percent of patients will have significant improvement or resolution of major obesity-related co-morbidities such as diabetes, hypertension, sleep apnea and hyperlipidemia following sleeve gastrectomy.4, 5,
