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 September 2026- Approximately 280,000 bariatric surgeries were performed in the U.S. in 2023, reflecting a 12% increase from the previous year (ASMBS).
- Sleeve gastrectomy remains the dominant procedure, accounting for 57% of all bariatric operations nationwide (ASMBS).
- Roux-en-Y gastric bypass represents roughly 22% of procedures, favored for its long-term remission rates for Type 2 diabetes (ASMBS).
- Nearly 42% of U.S. adults are classified as having obesity, driving the demand for metabolic and bariatric interventions (CDC).
- Bariatric revisions now account for 12.8% of procedures, addressing weight regain or reflux management (ASMBS).
Trending this month: Patients are increasingly choosing Sleeve Gastrectomy for its lower complication rates, while Roux-en-Y remains a top choice for severe metabolic disease. There is a rising shift toward minimally invasive SADI-S and ESG for patients seeking faster recovery.
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.
