Top procedures & treatments
Roux-en-Y gastric bypass
Restrictive + malabsorptive procedure with strong results for type-2 diabetes remission.
Sleeve gastrectomy
Removes ~80% of the stomach; the #1 bariatric procedure in the U.S. with average 60–70% excess weight loss.
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 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 most common bariatric procedure, accounting for roughly 58% of all weight loss surgeries (ASMBS).
- The 30-day mortality rate for bariatric surgery has dropped to 0.08%, making it safer than gallbladder removal or hip replacement (ASMBS).
- Over 42% of U.S. adults are now classified as having clinical obesity, driving a 20% increase in surgical inquiries since 2022 (CDC).
- Revisional bariatric surgeries now account for nearly 15% of total annual procedures as patients seek to manage weight regain or reflux (ASMBS).
Trending this month: Sleeve gastrectomy remains the top choice for its lower complication profile, though Roux-en-Y gastric bypass is trending upward for patients with severe GERD. Additionally, SADI-S is gaining popularity for its superior long-term metabolic outcomes in patients with BMI >50.
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.
