Ten-month-old Luis Manuel Gonzales weighs the same as an average nine-year-old but his parents and doctors are at a loss to explain his mystery weight gain.
Mom Isabel Pantoja, 24, from Colima, Mexico wasn’t worried about her son’s weight gain at first but the baby now dwarfs his brother Mario who is nearly three years older.
The family’s plight was reported by the Daily Mailwhere the family spoke of their daily distress not knowing what’s wrong with their son.
When he was born, he weighed a perfectly normal 8 lbs. just like his older brother, but pretty soon it became clear that Luis was different.
At two months he already weighed 22 lbs. and was wearing clothes for children two or three years older than him.
By ten months he weighed 62 lbs. and had doctors baffled.
Even dad Mario, who works at a local juice plant and is fit and well, is exhausted by carrying Luis.
Family members take it in turns to push him to his 4-times-a-week hospital appointments in a battered old push-chair.
Doctors have one theory that Luis could be suffering from Prader-Willi Syndrome, which is a genetic condition which leaves children constantly hungry and prone to massively over eating.
But Luis doesn’t beg for food and appears to eat a normal amount for a child his age.
The family’s plight came to the attention of Silvia Orozco, a surgeon specializing in nutrition who took an interest in the case.
She is awaiting results but has a theory that he could be helped by hormone injections.
His parents fear that if the diagnosis is confirmed, they will not be able to afford the proper hormone treatments, causing their son's weight to continue to balloon with the potential to cause death. The genetic condition causes an insatiable appetite, which leads to chronic overeating and obesity. It can also cause intellectual impairment and learning disabilities, according to the U.S. National Library of Medicine.
“After only one month we noticed that clothes did not fit him and we had to dress him in clothes for a 1-year-old, and even a 2-year-old,” Isabel Pantoja, the baby’s mother, told Metro.co.uk. “We saw our baby gain weight so fast. Sometimes he could not sleep because he felt like he was suffocating due to his weight.”
