How is my friend's little brother this tall and how tall will he be??!?

Question

My friend's little brother is only 12 and he's 6'3"!!! His parents are only 5'3" and 5'6" and nobody on EITHER side of his family has ever reached 6'0". How is this possible, and how tall should he plan on getting?

Answer 1

Sometimes, boys grow early. My brother did that: he was 6' tall when he was 12 years old, and never got any taller than that. My father was 6' tall and my mother was 5' tall.

I would suspect that there was a very tall grandparent on at least one side of the family. That happens more often than you might think. Your two parents got the short genes, but there were tall genes in the family and your brother got them. Don't worry. He may grow a few more inches, but probably not.

Answer 2

He has GIGNTISM. A gland disorder.
Pituitary gigantism
Pituitary gigantism due to growth hormone excess is the single condition that accounts for nearly all cases of pathologic extreme height. The excess growth hormone usually results from oversecretion by a group of somatotrope cells of the anterior pituitary gland (termed a "somatotrope adenoma"). These cells do not respond to normal controls of growth or function. They grow very slowly, so that for many years the only effects of such an adenoma are the effects of excessive growth hormone.

The primary effect of growth hormone excess in childhood is excessive growth, but the extreme height is accompanied by a characteristic physique recognizable to an endocrinologist. The typical physique involves heavy, thick bones, with large hands and feet and a heavy jaw. Once puberty is complete and adult height is achieved, continued thickening of the skin and growth of the jaw results in a combination of features referred to as acromegaly. Over decades, such an adenoma may reach a large enough size (2 cm or more in diameter) to cause headaches, impair vision, or damage other pituitary functions. Many years of growth hormone excess can cause other problems as well.

If a physician suspects pituitary gigantism or acromegaly, the simplest diagnostic screening test is measurement of insulin-like growth factor 1 in the blood. This is usually quite elevated but levels must be interpreted in relation to age and pubertal status. Additional confirmatory testing may include magnetic resonance imaging (MRI) of the pituitary to look for a visible adenoma, and suppressibility of growth hormone levels by glucose. Treatment depends on the size of the adenoma and may involve removal by a neurosurgeon, drugs such as octreotide or bromocriptine, or radiation. Treatment is discussed in more detail in the acromegaly article.

Childhood pituitary gigantism is a rare condition, and those affected are often unusual enough to attain a degree of celebrity status (for example, André the Giant). Acromegaly is the term used for the condition of growth hormone excess when it occurs in adults. Acromegaly is a far more common disease in adults than pituitary gigantism is in children.

How tall WILL he get??? Who knows.

Answer 3

ill be 21 quickly, im a woman and that i've got a 17 and 19 twelve months previous brother, a 14 twelve months previous sister and a 12 twelve months previous brother that are all taller then me. i actually have a 9 and 10 twelve months previous brother who will in all probability get taller then me. oh properly. im very almost 5'2

Answer 4

Have them to take his height at age 2 and double it to see how tall he will be. I did this with all 3 of my children and they all 3 are the height that it came out to be.

Answer 5

He might stop growing right now or he can grow a lot more. Not possible to tell, no one can predict how much or how tall. Many things can affect human growth.

Answer 6

no way of knowing how tall he will be, its a recessive gene could go back several generations.

Answer 7

WELL YOU STOP GROWING WHEN YOU 21 WELL WELL WOMEN DO MAN STOP AT 18 SO YA I GUESS HE WILL GROW MORE
