How tall can a human get?

Answer 1

A human can get around 15 ft but it would be a miracle too see that and can weigh over 1,000 pounds!

Answer 2

It depends on your gender, family background, personality traits. It also really depends on your eating habbit and etc.. It is uncertain how tall any human (of any size) will grow. After any person hits puberity it is physically impossible to grow any taller, but if that was true there would be 15 ft Giants walking around the earth.

The tallest man on Earth was Robert Waldow (an Illinois man) died at 8ft.11 in 1940 at the age of 22. The record may not stand for much longer, however. This week, Leonid Stadnyk, a 33-year-old living in a remote village in Ukraine, hit the news as the world's tallest living man. At 2.54m (8ft 4in), he is just 17cm short of Wadlow's record. In the past two years, he has grown 30cm.

Like Wadlow, Stadnyk owes his extraordinary height to a tumour on his pituitary gland. The tumour churns out growth hormone but it's a secondary effect that leads to the runaway growth that doctors call acromegalic gigantism.

Normally, the growth of our bones is limited by our sex hormones. A good burst of sex hormones at the right time tells the ends of our bones to stop growing. In acromegalic gigantism, as the tumour grows, it destroys cells in the pituitary gland that stimulate the release of sex hormones. The bones, therefore, never get the signal to stop growing.

But surely there must be a limit to a person's height? John Wass, a specialist in acromegalic gigantism at the University of Oxford, reckons it would be impressive to survive for long if you grew taller than 9ft.

First, high blood pressure in the legs, caused by the sheer volume of blood in the arteries, can burst blood vessels and cause varicose ulcers. An infection of just such an ulcer eventually killed Wadlow.

With modern antibiotics, ulcers are less of an issue now, and most people with acromegalic gigantism eventually die because of complications from heart problems. "Keeping the blood going round such an enormous circulation becomes a huge strain for the heart," says Wass.

Answer 3

The tallest human on record was Robert Wadlow, who stood at 8 feet 11 inches (272 cm) tall. Excessive growth can be caused by a condition called gigantism, which results from overproduction of growth hormone. However, extreme heights like Wadlow's are very rare and can have negative health implications.

Answer 4

humans get to about 12 to 13 feet tall and frog are usually about 5 or 6 feet tall but some have gotten to 10 + feet
