Mateo Hernandez, a four-month-old baby from texas, USA, began to grow long, black hair on his chest, back, arms, legs, face, and body due to a side effect of life-saving drugs and this has shocked his parents and family members. Mateo Hernandez was just one month old when he was diagnosed with congenital hyperinsulinism and in that condition, children will have abnormal levels of insulin. 


The baby was taken to hospital with a series of tremors and overeating and it is a rare disease in which the pancreas produces high levels of insulin or causes dangerous hypoglycemia conditions. The baby Mateo was later admitted to a private texas Children's Hospital and he was given life-saving treatment and his health improved within two weeks. 


However, after that, his parents, Brie Shelby, and Jared Hernandez noticed that the baby had an unusual side effect as they noticed black hairs started growing all over his body and they got shocked. The parents revealed that his hair started growing only after he started to take the medicines and the drugs and they told this to the medical team who were monitoring. But, the doctors said not to tonsure his head or crop his hair as that would make things worse and now a research team works on this side-effect.
