Sultan Kösen

Standing at 251 cm (8 ft 2.8 in), Sultan Kösen from Turkey holds the Guinness World Record for the tallest living man. His extraordinary height is due to acromegaly, a condition caused by a tumor affecting the pituitary gland, leading to excessive production of growth hormone. This condition resulted in his continuous growth into adulthood, necessitating the use of crutches for mobility. In 2010, Kösen underwent treatment in the United States, where doctors employed gamma-ray radiosurgery to halt his growth. Subsequent medical evaluations confirmed the success of this intervention, stabilizing his height.

Brahim Takioullah

Brahim Takioullah, hailing from Morocco, measures 246 cm (8 ft 1 in) tall. He holds the Guinness World Record for the largest feet on a living person, with his left foot measuring 38.1 cm (1 ft 3 in) and his right foot 37.5 cm (1 ft 2.8 in). Takioullah's exceptional height and foot size are attributed to acromegaly, similar to Kösen's condition. His remarkable stature has garnered significant public attention, leading to various media appearances and public engagements.

Morteza Mehrzad

Iran's Morteza Mehrzad stands at 246 cm (8 ft 1 in), making him the tallest man in Iran and the second tallest living man globally. Born with gigantism, Mehrzad's right leg ceased growing after a bicycle accident during his teenage years, resulting in a significant length discrepancy between his legs. He was introduced to sitting volleyball in 2011 after a coach noticed him on television and recognized his potential. Mehrzad has since become a pivotal member of Iran's national sitting volleyball team, contributing to their success in international competitions, including multiple Paralympic gold medals.

Dharmendra Pratap Singh

Dharmendra Pratap Singh from India is recognized as the tallest living Indian, with a height of 246 cm (8 ft 1 in). His towering stature has presented various challenges, including difficulties in securing employment and personal relationships. Despite these obstacles, Singh has utilized his unique appearance for public engagements and recently entered the political arena by joining the Samajwadi Party in Uttar Pradesh.

Rumeysa Gelgi

Rumeysa Gelgi, also from Turkey, holds the title of the tallest living woman, measuring 215.16 cm (7 ft 0.7 in). Her exceptional height is attributed to Weaver syndrome, a rare genetic disorder characterized by rapid growth and other physical abnormalities. Gelgi has leveraged her unique condition to raise awareness about Weaver syndrome and other rare diseases. She has been recognized with multiple Guinness World Records, including those for the largest hands (female), longest fingers (female), and longest back (female). Gelgi actively engages in public speaking and advocacy to promote understanding and support for individuals with rare conditions.
