A few words of thanks would be greatly appreciated.

Bariatric surgery - Definition


Bariatric surgery is a surgical technique used in some cases of severe obesity. This technique is reserved for obese people whose lives are threatened by their condition when all other treatments have failed. It involves the placement of a gastric band (called gastroplasty), which reduces the size of the stomach, or a bypass system in the digestive tract to reduce the absorption of nutrients. Generally, a significant weight loss is observed in the aftermath of this kind of intervention. This is major surgery requiring a long postoperative follow-up and change in eating habits.
