Top procedures & treatments
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.
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 August 2026- Sleeve gastrectomy remains the dominant procedure, accounting for 58.6% of all bariatric surgeries performed in the U.S. (ASMBS)
- Metabolic and bariatric surgery rates increased by 5% year-over-year as safety profiles for Roux-en-Y and SADI-S continue to improve (ASMBS)
- Total bariatric procedures reached 280,000 annually, driven by a 15% rise in revisional surgeries to address weight regain or reflux (ASMBS)
- Severe obesity affects 9.2% of U.S. adults, yet fewer than 1% of eligible candidates currently undergo surgical intervention (CDC)
Trending this month: Sleeve gastrectomy remains the top choice for its technical simplicity, while SADI-S is surging in popularity for patients seeking maximum weight loss. Additionally, endoscopic sleeve gastroplasty (ESG) is growing as a preferred non-surgical gap therapy.
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.
