5-Year-Old Boy Weighs A Shocking 178lbs A FIVE-YEAR-OLD boy weighing more than 12 STONE is so large he risks being suffocated by his own bulk. Misael Caldog** Abreu is three times the size of other children his age due to a syndrome which means he is unable to stop eating. He is so heavy he often stops breathing while sleeping - leaving his terrified parents fearing that one day he may **t wake up. Misael, from Espírito Santo, Brazil, was born a healthy 6lb 6oz, but immediately started piling on the pounds. Doctors believe he may be suffering from Prader-Willi syndrome, a rare genetic condition that leaves him with an insatiable appetite. His mother Josiane de Jesus Caldog** Abreu and father Ma**el Abreu worry he will die without help.
