Have you guys heard about this?
He was 2 and a half and weighed 72lbs when he underwent gastric bypass. He had surgery in 2010 and in 2012 he was 52lbs. They ran tests and everything turned out normal, from the various articles I've read it sounds like the parents didn't keep up with the special diets.
Barring any medical condition, which it seems there was no evidence of, I would consider this child abuse. They put that boy's life in danger by letting him get morbidly obese.
