Bariatric Surgery My husband did a bariatric surgery eight years ago and he´s very fine know, but a lot of people can not be well after this kind of surgery because they have a lot of difficult in the recovery process right after that , especially because they can not eat as they ate before; Another problem is that they can develop other addictions like drink alcohol or do exercises exhaustively. An important thing to do before the surgery is to attend a psychologist for at least two years as well as a nutritionist and be mentally prepared.
