They think it's the holy grail of weight loss. They think that they can just wake up from surgery and they will start getting thinner with no effort on their part. What they don't realize is that there is a huge risk of complications associated with bariatric (or any) surgery. Patients have died from eating too much and bursting their stomach pouches open. Infections can occur. And a lot of patients gain the weight right back because they go back their same shitty eating habits and stretch their stomach pouch.
