It can cause erosions, severe acid reflux, can even wear its way into the stomach and require major surgery to repair. I would suggest the Gastric
Sleeve operation over the Gastric Band
. Plus, your son would have to go frequently to get 'fills' on the band...a huge pain in the rear. Too tight, and he will not be able to swallow anything down. Too loose, and he won't have good restriction and will lose little to no weight. I would suggest the Gastric Sleeve.
