Eleven-month-old Colombian baby has wieght of an eight-year-old
The child's mother, Milena Orosco de Agudelo, said her son's unusual growth spurt began when he was just two months old.
He has had several medical examinations carried out which suggest he may have a problem with his endocrine system.
Miss Orosco de Agudelo said: "He had some tests done and the results show that he has a thyroid malfunction.
"Then, he had a cardiogram test done and that test shows that he has the bones of an eight-year-old boy, but they have not told me where that came from."
Doctor David Dias, of the Barranquilla Pediatric Hospital, said more examinations need to be carried out to discover why the child has become so large.
He said: "The baby will have tests done to see if he's obese or we're dealing with hyperthyroidism," he said.
