“All I have to say, it’s the best thing I’ve ever done for myself. I’ve struggled with my weight for years and tried so many diets. I turned 30 this past January and decided this was my gift to myself. Yes, it’s hard, but being overweight is harder. In just a few months I went from hiding from the world…to wanting to see the world. 75lbs ago I would have never thought I would be tucking in my shirts or love taking hikes. But here I am happy, healthy, and freaking grateful for Mexico Bariatric Center.”

What to Expect After Gastric Sleeve Surgery
Gastric bypass has become one of the longest performed bariatric surgeries with massive amounts of patient success to combat morbid obesity. Gastric bypass surgery is a more complex procedure due to using both restriction and malabsorption to provide patients with substantial weight loss.
Average expected weight loss results are:
*Individual results may vary

Major Life-Changing Benefits
- Expected weight loss of 65-75% within first-year post-op
- Successful in removing, improving, or remission of obesity-related comorbidities (health concerns)
- Improved quality of life
- Non-scale victories (NSV’s)
- Feel better about yourself and a boosted sense of self
- Lifestyle changes
Your Skin After Gastric Bypass Surgery
The RNY gastric bypass is performed laparoscopically, making it minimally invasive using 4 to 5 abdominal incisions. This reduces scarring and promotes healing/recovery. The drawback of losing weight rapidly is increasing the possibility of having excess, sagging skin. There are ways to reduce excess skin, although sometimes plastic and cosmetic surgery is needed to remove it in places like the arms, thighs, stomach, etc.
Loose, Sagging, and Excess Skin
Loose skin becomes apparent after significant weight loss. Everyone has different skin elasticity, meaning some people have excess skin after gastric bypass and some people do not. If sagging skin exists, plastic surgery procedures may help.
