Average sleeve patient loses 55-65% of excess weight in year 1. For a 270-pound patient with ideal weight of 150 (120 lbs excess), that is approximately 70 lbs lost in year 1, reaching 200 lbs. Year 5: 50-55% sustained. Year 10: 45-50% sustained for compliant patients. 30-40% of patients experience meaningful regain by year 5 if they do not maintain behavioral changes.

Yes for most measures. Sleeve has lower perioperative complication rate (2-3% vs 3-5% for bypass), lower perioperative mortality (0.1-0.2% vs 0.2-0.3%), shorter operative time, and less demanding lifelong nutritional supplementation. Bypass produces somewhat more weight loss and better diabetes remission, but at higher surgical risk.
