Gastric sleeve is the operation everyone prices. Gastric bypass is the operation many of them end up needing: it remains the reference procedure for severe reflux, for type 2 diabetes remission, and for the growing number of sleeve patients whose weight returns or whose reflux becomes intolerable. Revision surgery, converting one procedure to another, is the fastest-growing category in bariatrics and the least-published price. This table covers the three columns the sleeve tables skip.
Key takeaways
- Roux-en-Y bypass prices 10–25% above sleeve in every country; revision surgery prices 20–40% above a primary bypass.
- US cash packages for bypass run $20,000–$35,000; Colombia bundles it at $7,000–$12,000 including nights and the nutrition program.
- Insurance denial is the reason most Americans are reading this: bariatric coverage is excluded or gated by BMI and documentation on a large share of plans.
- The operation is one afternoon. The product is five years of follow-up. Price the follow-up, not just the surgery.
The by-country table
Ranges are for adult primary laparoscopic Roux-en-Y gastric bypass, one-anastomosis (mini) gastric bypass, and revision surgery (most commonly sleeve-to-bypass conversion or a re-sleeve). Duodenal switch and SADI-S price at or above bypass. For sleeve gastrectomy alone see our existing gastric sleeve comparison.

Roux-en-Y gastric bypass: typical 2026 range by country
What actually moves the number
Procedure
Sleeve is the simplest and cheapest; bypass adds an intestinal anastomosis and operating time; revision adds scar tissue, longer surgery and higher leak risk. The price ladder is consistent across countries.
Pre-op program
US bariatric programs require dietitian visits, psychological evaluation, labs, sometimes an endoscopy and a supervised weight-loss period, often over three to six months and often billed separately. International packages compress this into a pre-op day and bundle it.
Nights
Two to three nights is standard abroad and included; US programs increasingly discharge on day one or two.
Follow-up and nutrition
Lifelong vitamin supplementation, labs every six to twelve months, and dietitian access. Cheap abroad, but you will be doing it at home; arrange a US primary-care physician willing to manage post-bariatric labs before you fly.
BMI and comorbidities
Higher BMI, prior abdominal surgery and sleep apnea raise anesthesia risk and price. Reputable centers have upper limits and will say so.
Complication coverage
Leak, stricture and bleeding are uncommon but expensive. Some international centers include a complication guarantee; independent complication insurance is available and worth pricing.
Sleeve, bypass, or revision: the price is the wrong first question
Bypass generally produces slightly more weight loss and better diabetes remission than sleeve, at the cost of more nutritional deficiencies and dumping syndrome. Sleeve is simpler but worsens reflux in a meaningful share of patients, and reflux is the leading reason for later conversion to bypass. Revision surgery has a higher complication rate than any primary procedure, which is why volume matters most here: ask any surgeon, in any country, how many revisions they do a year and what their leak rate is. If a center does not track that, it is the wrong center.
Worked example: the all-in trip math
A country table is only useful if you finish the arithmetic. Here is an illustrative all-in build for Roux-en-Y gastric bypass in Colombia against the midpoint of the US cash-pay range, using 12 days of lodging in Medellín and one economy round-trip from the US Southeast. Every line is a typical 2026 range, not a quote, and you should rebuild it with your own numbers.
| Line | Low | High | Notes |
|---|---|---|---|
| Procedure bundle (Colombia) | $7,000 | $12,000 | Surgeon, anesthesia, facility, standard nights, first follow-up |
| Lodging, 12 days | $720 | $1,680 | Furnished apartment or hotel via short-term rental platforms; recovery houses sit mid-range |
| Flights, 1 person round-trip | $450 | $900 | Direct from Miami, Fort Lauderdale, Houston, Atlanta, New York |
| Contingency buffer (10–20% of bundle) | $950 | $1,900 | Extra labs, an extra night, medications, ground transport, currency movement |
| All-in trip | $9,120 | $16,480 | Add a companion's flight and meals if travelling with one |
| US cash-pay midpoint | $27,500 | Midpoint of the published range above; your local quote may be higher or lower | |
| Indicative gap | $11,020 | $18,380 | Before lost wages, complication insurance, or a companion |
Paying the bundle by international transfer rather than card usually saves 2–4% in fees and spread; we use Wise for this and receive a small referral commission if you open an account through that link, at no cost to you. A companion is strongly advised for bariatric trips; add their flight and meals.
Where Colombia sits, and how to read it
Colombia appears in the middle-to-low band on almost every row of this table, and for North American patients it carries a logistics advantage the cheaper Asian rows cannot match: three to five hours of direct flight from Miami, Houston, Atlanta, New York and Fort Lauderdale, and a same-or-adjacent time zone for follow-up calls. The World Health Organization ranked Colombia's health system #22 in the world and #1 in the Western Hemisphere in its 2000 World Health Report; that ranking is now a historical benchmark rather than a current league table, but it reflects a system that was built on universal coverage and a strong private hospital tier. Six Colombian hospitals hold Joint Commission International accreditation as of 2026 — accreditation is hospital-level, and it does not extend to freestanding clinics or to individual surgeons.
Two verification anchors matter more than any price. First, any Colombian physician can be checked in the national ReTHUS registry (rethus.gov.co), which confirms licensure and specialty. Second, the facility should be able to show its habilitación (operating license) for the specific service line. A low number from a facility that cannot produce either is not a bargain; it is an unpriced risk.
Bariatric surgery in Colombia is concentrated in the large private hospital groups, with surgeons trained in high-volume programs and, at the major centers, on-site ICU and endoscopy for managing complications. That hospital setting is the main reason Colombia's band is tighter than Mexico's.
Sources and method
US ranges use bariatric-center published cash packages, hospital price-transparency cash-price fields (DRGs 619–621 and CPT 43644/43775/43848) and FAIR Health benchmarks. International ranges use published hospital and bariatric-center price lists and comparative price reports, cross-checked across at least two sources per cell. Method: where our numbers come from.
Frequently asked questions
How much does gastric bypass cost without insurance in the US?
Typical 2026 cash packages at US bariatric centers run roughly $20,000–$35,000 for Roux-en-Y bypass, with pre-op program costs often separate and hospital list prices higher.
How much more does bypass cost than a sleeve?
Roughly 10–25% more in every country, reflecting the added anastomosis and operating time. Revision surgery adds another 20–40% over a primary bypass.
Why does bariatric surgery abroad cost so much less?
Bundled pricing, lower facility and labor costs, and pre-op programs compressed into a day or two rather than months of separately billed visits. The operation itself is the same laparoscopic procedure.
How long do I need to stay abroad after gastric bypass?
Most programs ask for 10–14 days before a long flight, covering the hospital stay and the first follow-up. Bring a companion.
How much does gastric bypass cost in Colombia?
Typical 2026 bundled ranges at major Colombian hospitals are roughly $7,000–$12,000 for Roux-en-Y bypass and $8,000–$14,000 for revision surgery, including nights and the nutrition program. Typical ranges, not quotes.
