Colossal Baby Confounds Doctors

CHEN: It's no mystery that some children are just naturally big. But it is a mystery how an eleven-month Colombian child got to be so unnaturally huge. Let's find about more about this little BIG boy. STORY: The boy's mother, Milena Orosco de Agudelo, says her son's exponential growth began when he was just sixty days-old. Tests show the baby has an endocrine system condition, as well as some other medical problems. [Milena Orosco de Agudelo, Boy's Mother]: "He had some tests done and the results show that he has a thyroid malfunction. Then, he had a carpogram test done and that test shows that he has the bones of an 8 year-old boy, but they have not told me where that came from." Dr. David Dias of the Barranquilla Pediatric Hospital says the baby is still undergoing testing. [Dr. David Dias, Pediatric Physician]: "The baby will have tests done to see if he's obese or if we're dealing with hyperthyroidism." The normal weight for an eleven-month old boy is between thirteen and sixteen pounds. But because of his weight, he cannot even wear his older brother's old clothes, and is limited to wearing extra large diapers.
