Gastric bypass in Tijuana: the procedure with the longest track record
The Roux-en-Y gastric bypass has been performed for more than fifty years. It is often the preferred option when obesity comes with type 2 diabetes or severe acid reflux.

Gastric Bypass Surgery
The surgeon creates a small stomach pouch, about the size of an egg, and connects it directly to the small intestine. Food skips most of the stomach and the first part of the intestine, so you eat less, absorb fewer calories and experience hormonal changes that improve blood sugar control.
It is performed laparoscopically. Because it changes how nutrients are absorbed, lifelong vitamin and mineral supplements and periodic lab work are part of the commitment.
When a bypass is usually considered
- BMI of 40 or higher, or 35 with related conditions
- Type 2 diabetes that is hard to control
- Severe gastroesophageal reflux
- A previous sleeve with weight regain or reflux
- Commitment to lifelong supplements and follow-up
The indication is confirmed at your evaluation.
Your gastric bypass, step by step
Evaluation
History, lab work, cardiac and internal medicine assessment, and in some cases an endoscopy before surgery.
Pre-op diet
Liquid, low-calorie diet before surgery to reduce the size of the liver.
Surgery
Laparoscopic Roux-en-Y bypass under general anesthesia, usually between one and a half and two hours.
Recovery
Hospital stay of one to two nights, early walking, staged diet and a supplement plan that starts in the first weeks.
Life after a bypass
Portions are small and sugar is poorly tolerated: sweets can cause dumping syndrome, with nausea, sweating and dizziness. Protein comes first at every meal, vitamins are taken daily for life and lab work is checked periodically to prevent deficiencies of iron, B12, calcium and vitamin D.
What people ask most
Sleeve or bypass: which one is better?
Neither is better for everyone. The sleeve is simpler and does not affect absorption; the bypass tends to be preferred with diabetes or severe reflux. The decision is made at your evaluation, with your history in hand.
What is dumping syndrome?
It is the reaction that happens when sugary or very fatty food reaches the intestine too quickly: nausea, cramps, sweating, palpitations. It is avoided by following the diet.
Will I need vitamins forever?
Yes. After a bypass, daily supplements and periodic lab work are permanent.
