Average Weight Loss

People often wonder: "how much weight am I going to lose?" It really depends on multiple factors: the first of which would be: "which operation did you have?" With the lap band, the weight loss that a patient can experience afterwards is quite variable. On average, we somewhere around 45% excess body weight loss, which means 45% of however much a patient weighs is what what they will lose. So if an individual weighs 100 pounds over their ideal body weight, they would typically lose about 45 pounds with a lap band. With a sleeve gastrectomy, we see about 60% excess body weight loss, meaning an individual that is 100 pounds overweight will lose about 60 pounds. With the gastric bypass we typically see about 65-70% excess body weight loss.
