The world's tallest man may have reached his peak height after doctors in the US treated the gentle giant's excessive growth disorder.
Sultan Kosen has been placed on medication to treat his disproportionate levels of testosterone and doctors in Virginia believe the pioneering treatment could finally stop his continued growth.
His gigantic appearance is the result of a condition called acromegaly, which is usually caused by a tumour in the pituitary gland.
Neurosurgeon Jason Sheehan, from Virginia Medical Centre, who helped treat Kosen, said: 'I'm most pleased that we were able to help Sultan.
'If he had continued to grow, it would have been life-threatening.'
The 29-year-old was named the world's tallest man by Guinness in 2011, overtaking former record holder Bao Xishun who stands at 7ft 8.9in. Doctors in Turkey say Kosen, who wears size 28 shoes, has showed no further signs of growth since returning home.
Kosen has said that despite his towering height he 'enjoys a normal lifestyle'.
