My husband had the sleeve done 2 years ago and it was a godsend. He no longer needs a c-pap to sleep, he is off his blood pressure med, and his health in general has improved more than we could ask for. The procedure was done laposcopic and he was out of the hospital in 2 days. He was standing at his bedside and sitting in a chair 2 hours after surgery. The first post op day, he was walking the halls. He has had no complications or problems since surgery. The two things I would ask your surgeon is--How big of a sleeve does he leave. My husband's is 30 cc. Many times the surgeons in the US leave 50 to 60 cc and patients gain some of the weight back. With a 30 cc sleeve it is almost impossible to gain weight unless you eat nothing but high calorie, high fat foods. The smaller sleeve just doesn't allow you to eat a lot yet you can eat anything that you want just less of it. The second thing is, if you have your gallbladder, does your surgeon go ahead and remove it at the time of surgery. If not, will he remove it at that time? The weight loss from the surgery is fast and almost everyone I know that had the surgery and didn't have their gall bladder removed had to go back to surgery in less than 6 months and have it removed. I personally know of 10 people who have had a sleeve done and not one of them has had a problem and each of them would not hesitate to do it again. The people I know that have had a roux n y or gastric banding have all gained some of their weight back or had problems with the gastric band.
