Growing up
Sultan was born on 10 December 1982, but he didn’t start his incredible growth spurt until he was 10 years old.
The rest of his family, including his parents and four siblings, are all average size.
Sultan's unique growth and massive height is caused by a condition known as "pituitary gigantism", which is the result of an over-production of growth hormone.
Growth hormone is released from the pituitary gland in the brain; if the gland is damaged by a tumour, for example, it can release too much (or too little) hormone. The effects of over-production include large hands, a thickening of the bones and painful joints.
Due to his extreme size, Sultan was never able to finish school and instead began working as a farmer to support his family.
He previously described one of the advantages of being tall as being able to help his mum out with jobs such as changing a broken light bulb and hanging curtains.
As for the disadvantages to his height, he complained about not being able to find clothes or shoes that fit and finding it extremely hard to fit into a regular-size car.
As a teenager, Sultan was signed to the Galatasaray basketball team, but unfortunately he was too tall to play. However, he remains a fan of the sport to this day.
