Top procedures & treatments
Revisional bariatric surgery
Converts a prior sleeve, band, or bypass when weight regain or reflux occurs.
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.
Duodenal switch / SADI-S
Most powerful surgical option for BMI 50+, with average 80%+ excess weight loss.
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 the most recent reporting cycle (ASMBS).
- Sleeve gastrectomy remains the dominant procedure, accounting for roughly 58% of all primary weight loss surgeries (ASMBS).
- Metabolic surgery reduces the risk of all-cause mortality by 30% and improves type 2 diabetes remission rates by over 60% (ASMBS).
- Non-surgical Endoscopic Sleeve Gastroplasty (ESG) has seen a 15% year-over-year increase in adoption for patients with a BMI between 30 and 35 (ASGE).
- Revisional bariatric surgeries now represent approximately 15% of the total annual procedural volume to address weight regain or reflux (ASMBS).
Trending this month: Patients in 2026 are increasingly opting for Sleeve Gastrectomy and SADI-S due to their superior metabolic profiles. There is also a surge in Endoscopic Sleeve Gastroplasty (ESG) for those seeking incisionless options with faster recovery times.
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.
