Top procedures & treatments
Duodenal switch / SADI-S
Most powerful surgical option for BMI 50+, with average 80%+ excess weight loss.
Sleeve gastrectomy
Removes ~80% of the stomach; the #1 bariatric procedure in the U.S. with average 60–70% excess weight loss.
Roux-en-Y gastric bypass
Restrictive + malabsorptive procedure with strong results for type-2 diabetes remission.
Revisional bariatric surgery
Converts a prior sleeve, band, or bypass when weight regain or reflux occurs.
Endoscopic sleeve gastroplasty (ESG)
Non-surgical, suture-based stomach reduction for BMI 30–40.
By the numbers
Updated October 2026- Approximately 280,000 metabolic and bariatric procedures are performed annually in the U.S. as of 2024 (ASMBS).
- Sleeve gastrectomy remains the most common bariatric procedure, accounting for roughly 58% of all weight loss surgeries (ASMBS).
- Over 42% of U.S. adults are now classified as having clinical obesity, driving a 10% year-over-year increase in surgical consultations (CDC).
- Roux-en-Y gastric bypass represents approximately 19% of procedures, remaining the gold standard for long-term GERD resolution (ASMBS).
- The rate of revisional bariatric surgery has risen to nearly 15% of total annual procedures to address weight regain or complications (ASMBS).
Trending this month: Patients in 2026 are increasingly opting for Sleeve Gastrectomy for its lower complication profile, while interest in Endoscopic Sleeve Gastroplasty (ESG) is surging among those seeking non-surgical, incisionless alternatives to traditional bariatric stapling.
How to choose the right specialist
Verify board certification, ask how many of your specific procedure the clinician performs each year, and review patient outcomes — not just star ratings. A bariatric & weight loss provider who clearly explains your options, the evidence, and the realistic recovery timeline is worth more than the most heavily advertised name.

Frequently asked questions
What BMI qualifies for surgery?
Most insurers cover BMI ≥35 with a comorbidity or BMI ≥40 without; ASMBS now endorses surgery at BMI ≥30 with metabolic disease.
Is the sleeve reversible?
No — sleeve gastrectomy permanently removes part of the stomach. Bypass is technically reversible but rarely undone.
