A Mexican mother whose 10-month-old son weighs the same as a nine-year-old has spoken out about his mystery condition.
Isabel Pantoja, 24, from the Pacific coast state of Colima, said at first she assumed the baby Luis’s growth was down to the fact that “I had good breast milk” but now she is desperately worried for her son.
She also revealed the family take it in turns to push the boy to a local hospital where doctors are baffled by his condition, reports the Daily Mail.
One of the main hypotheses is that the boy could have a disease called Prader-Willi Syndrome, a genetic condition in which children have an insatiable appetite and weak muscle tone.
However, Luis does not eat voraciously or spend the day demanding food.
Medics are considering giving him with hormone treatment that can cost $555 per shot, despite his father earning just $200 per month.
At birth Luis weighed 3.5kg (8lbs), about the same as his brother Mario, who is almost three but is now dwarfed by his baby brother.
At two months of age, Luis weighed 10kg (22lbs). Over the next eight months he gained a staggering 18kg (40lbs).
His parents have since created a Facebook page and opened a bank account for people to donate money for Luis Manuel’s medical care.
They take turns pushing him to the hospital in a decrepit stroller for daily blood tests.
