What to Expect After Gastric Sleeve Surgery

Gastric bypass surgery has become one of the longest-performed bariatric surgeries with massive amounts of patient success to combat morbid obesity. The Roux-en-y gastric bypass is a complex procedure that combines restriction and malabsorption to help patients lose a substantial amount of weight.

Average expected weight loss results are:

  • 3 months post-op: 30-40% excess weight loss*

  • 6 months post-op: 50-55% excess weight loss*

  • 12 months post-op: 65-75% excess weight loss*

  • 18 months post-op: 70-80% excess weight loss*

*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 methods to reduce excess skin, but plastic and cosmetic surgery may be needed for areas 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.

Mexico Bariatric Center® shares Tijuana gastric bypass before and after pictures for those who haven’t committed to weight loss surgery yet to gain insight on the results.
