Stadnyk's excessive growth began after brain surgery when he was 14 years old. He developed a pituitary gland tumor which caused the gland to secrete large amounts of growth hormone, resulting in what doctors describe as acromegalic gigantism. Twenty years after the surgery, the doctors have discovered the tumour had mysteriously disappeared and he is currently healthy. A Pravda news report in Spring 2006 reported that Stadnyk grew 2 cm (0.79 in) in the previous year, not accounting the time between the original Spring 2004 report and Spring 2005. According to Pravda, his health is slowly failing in that he needs to hold on to limbs of trees and the side of his house to walk about. His recorded weight is 200 kg (440 lb).
