My son is 13 years old. His height is more than normal, he is currently 5'10" tall. Because of his height he looks older than his age. His height has grown a lot since he turned 10. He has no health problems otherwise. Is this normal, Dr?
Ans: It depends on the height of other family members like parents, uncles, grandparents . Also has he developed any signs of puberty? This sudden growth spurt usually indicates start of puberty and final height is generally an average of parental heights. To determine whether this is part of pubertal growth spurt, bone x-rays are advised.
