Weight Loss Surgery · Tijuana, Mexico
The main difference between a mini gastric bypass and a standard gastric bypass is the number of intestinal connections: the mini (single-anastomosis) bypass uses one connection instead of two, making it technically simpler with a shorter operative time, while the Roux-en-Y bypass uses two. Both produce significant, comparable weight loss; they differ in surgical complexity and reflux profile, and the right option depends on your anatomy and clinical history — determined at your free evaluation. At Russald Medical Center in Tijuana, both cost 65–75% less than in the US.
