A 10-month-old baby weighs as much as a nine-year-old at a massive four stone and 10 pounds.
Luis Manuel weighed a normal healthy weight when he was born at seven pounds and 11 onces, but since then he has piled on the pounds .
His parents suspect the tot, who has struggled to breathe because of his super rapid weight gain, suffers from Prader-Willi syndrome.
This is the same condition affecting Katie Price’s son, Harvey, who weighs 18 stone.
It is a genetic disorder and means those affected are permanently hungry.
His mother Isabel Pantoja said: “After only one month we noticed that clothes did not fit him and we had to dress him in clothes for a one-year-old, and even a two-year-old.
“We saw our baby gain weight so fast. Sometimes, he could not sleep because he felt like he was suffocating due to his weight.”
Luis’ parents have now launched a fundraising campaign to pay for his treatment if his diagnosis is confirmed by doctors in Tecoman, Mexico.
Treatment would consist of a series of hormone injections, with each one reportedly costing more than £400.
