Projections are editorial estimates based on publicly listed 2026 pricing. Real-world cost depends on insurance plan, manufacturer coupon eligibility, dose level (lower doses often cost the same as max doses), and whether you stay on a given path the full projection horizon. Surgery cost varies widely by region and surgeon.
How to read this
Self-pay calculus is straightforward. Bariatric surgery's ~$18,000 year-1 cost is paid back vs Wegovy NovoCare ($5,988/year) in about 3 years. Vs LillyDirect Zepbound vials, similar breakeven. Vs orforglipron ($1,788/year), surgery doesn't break even for ~10 years.
Insured patients with prior authorization approval and a $25/mo copay see the math flip — medication is much cheaper than surgery on any horizon. The risk: insurance changes, employer changes, or PA renewal denials. Self-pay paths give cost certainty.
