What are the pros and cons of a gastric sleeve and a gastric bypass?

Sleeve vs Bypass: You should have a detailed conversation about this with a bariatric surgeon. Briefly, a gastric sleeve is a simpler, shorter operation with less perioperative and nutritional complications. However, the long term results aren't quite as good as bypass. I'm barely scratching the surface of this issue, so again you need to make this decision after and in-depth evaluation with a bariatric surgeon.
