Mini Gastric Bypass in Mexico — From $5,900, ~70% Excess Weight Loss
A simpler, faster bypass with comparable results to Roux-en-Y. Single anastomosis, ~1-hour surgery, easier to revise. Performed by Dr. Alejandro López's team — 20,000+ procedures, accredited hospitals, all-inclusive package.
What Is Mini Gastric Bypass?
The Mini Gastric Bypass — also called One-Anastomosis Gastric Bypass (OAGB) — creates a long, narrow stomach pouch and connects it directly to a single loop of small intestine. One connection instead of the two used in Roux-en-Y, which means a faster, simpler surgery with less technical risk.
Performed laparoscopically through 4–5 small incisions, the operation takes about an hour. Despite being newer, the mini bypass produces weight loss and metabolic results comparable to traditional Roux-en-Y.
- One anastomosis (connection) — fewer technical risks
- Shorter operating time (~1 hour vs 90 min)
- Comparable ~70% excess weight loss at 1 year
- Easier to revise or convert if needed
- Strong metabolic effect — diabetes resolution similar to RYGB
How the Mini Bypass Causes Weight Loss
Three mechanisms work together — restriction, malabsorption, and gut hormone changes.
Restriction
Your stomach is reduced to ~80% smaller than before — a long, narrow tube. You feel full quickly and eat smaller portions automatically.
Malabsorption
A loop of small intestine is bypassed, so your body absorbs fewer calories from the food you do eat.
Hormonal Reset
Gut hormones (ghrelin, GLP-1) shift dramatically — hunger drops, blood sugar improves, and type 2 diabetes often resolves within days.
Mini Gastric Bypass vs Traditional Roux-en-Y
Both are highly effective. The mini bypass trades a few decades of long-term data for a simpler, faster surgery with comparable outcomes.
| Factor | Roux-en-Y | Mini Gastric Bypass |
|---|---|---|
| Connections (anastomoses) | 2 | 1 (simpler) |
| Surgery time | ~90 minutes | ~60 minutes |
| Excess weight loss (1 yr) | ~70% | ~70% |
| Type 2 diabetes resolution | ~80% | ~75–80% |
| Long-term data | 50+ years | ~20 years |
| Reversible/revisable | Yes | Yes (easier) |
| Bile reflux risk | Very low | Slightly higher |
| Starting price (Mexico) | From $5,900 | From $5,900 |
Is the Mini Bypass Right For You?
The mini bypass is excellent for patients who want bypass-level results with a simpler, faster surgery.
✅Ideal Candidates
- BMI of 35+ (or 30+ with obesity-related conditions)
- Type 2 diabetes — strong metabolic effect
- Want bypass-level weight loss with shorter surgery
- Plateaued or regained weight after gastric sleeve
- Patients seeking an easier-to-revise option
- Adults 18–65 in generally stable health
⚠️Roux-en-Y May Be Better If
- You have severe pre-existing acid reflux/GERD
- You prefer a procedure with longer-term safety data (50+ years)
- You've had previous abdominal surgery in specific areas
- You can't commit to lifelong vitamin supplementation
