March 16, 2012 > World's tallest man may have stopped growing World's tallest man may have stopped growing Submitted By AP Wire Service CHARLOTTESVILLE, Virginia (AP), Mar 13 - Thanks to treatment by researchers at the University of Virginia Medical Center, the world's tallest man may have reached his peak. Measuring at 8-feet-3 inches (2.51 meters), 29-year-old Sultan Kosen of Turkey is listed in the 2011 Guinness World Records at the tallest living man. Kosen visited the university in May 2010 for treatment for a disorder called acromegaly, which is usually caused by a tumor in the pituitary gland. The Richmond Times-Dispatch (http://bit.ly/AtJeHK ) reports that Kosen was placed on a new medication that could potentially help control the production of growth hormone and stop his continued growth. According to university officials, doctors in Turkey say Kosen has stopped growing.
