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 August 2026- Sleeve gastrectomy remains the dominant procedure, accounting for 58.6% of all bariatric surgeries performed in the U.S. (ASMBS 2024-2025)
- Bariatric revisions and repairs have increased to approximately 16.7% of total procedures as long-term weight maintenance becomes a priority (ASMBS 2025)
- Total annual metabolic and bariatric procedure volume reached 280,000 cases as safety profiles and insurance coverage continue to expand (ASMBS 2025)
- Severe obesity affects 9.2% of U.S. adults, driving a steady 5% annual increase in surgical intervention rates (CDC 2026)
Trending this month: Patients are increasingly selecting sleeve gastrectomy for its efficiency, while the SADI-S and revisional surgeries are rising as patients seek advanced solutions for metabolic disease and weight regain management.
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.
