Weight regain after gastric sleeve happens through two pathways: mechanical and metabolic. A bariatric surgeon explains both with 10-year data. If you had a sleeve gastrectomy and the weight is coming back, this video explains exactly what is happening and what you can do about it. Weight regain after sleeve gastrectomy is not rare. In a multicenter study of 830 patients followed for nearly 10 years, 64 percent regained more than 10 percent from their lowest weight. A separate study found that only 20 percent maintained appropriate weight loss beyond 5 years. These numbers are not meant to discourage. They are meant to prepare. In this video, I break down the two distinct pathways of weight regain after sleeve gastrectomy, the complete diagnostic workup, every treatment option, and how to protect your results going forward. TOPICS COVERED IN THIS VIDEO: How common is weight regain after sleeve gastrectomy (10-year multicenter data) The mechanical pathway: sleeve dilation, 3D CT volumetry, and loss of restriction The metabolic pathway: ghrelin rebound, leptin resistance, metabolic adaptation The environmental factor: ultra-processed foods and the 508-calorie experiment How to tell mechanical from metabolic regain: the complete workup Treatment for metabolic regain: GLP-1 receptor agonists (semaglutide, tirzepatide, liraglutide) Treatment for mechanical regain: revisional surgery (RYGB, SADI-S, OAGB, endoscopic revision) Body composition: why resistance training and protein protect your metabolism The single strongest predictor of lower regain (it is not diet or exercise) DATA SOURCES: 2026 multicenter retrospective study of 830 sleeve patients (median follow-up 9.8 years) Multicenter study of 339 sleeve patients (mean follow-up 7.1 years) 10-year single-center study of 156 sleeve patients 10-year prospective cohort of 300 sleeve patients Long-term study of 578 sleeve patients (mean follow-up 8.8 years) PCORnet Bariatric Study (sleeve vs bypass 5-year comparison) Systematic review of weight regain following sleeve gastrectomy Meta-analysis of 28 studies on gut hormones after sleeve gastrectomy (653 patients) Systematic review of 32 studies on risk factors for weight regain (13,000+ patients) Meta-analysis of 19 studies on GLP-1 receptor agonists after bariatric surgery 2026 ASMBS statement on treatment options for non-response and weight recurrence Network meta-analysis of 23 studies on revisional procedures after sleeve 2026 propensity-matched study of endoscopic vs surgical revision (220 patients) Controlled clinical trial on resistance training and protein supplementation after RYGB Meta-analysis of 33 studies on exercise and body composition after bariatric surgery Lancet series on ultra-processed foods and human health Randomized controlled trial on ultra-processed vs unprocessed diets (508 kcal difference) CHAPTERS: -- Introduction: Your Sleeve Worked.
