Recently on an episode of SBS’ Star King, Leeteuk’s trainer revealed that Leeteuk suffers from Scoliosis, a medical condition in which the spine is bent to the side instead of going down in a straight line when viewed through an X-ray. Leetuek’s condition was pointed out while showing photos of Leetuek after 50 hard workout days for the Buff King contest. Looking at the pictures, Leeteuk’s trainer explained that the muscles where uneven because of his case of Scoliosis. His trainer stated,
“His muscles have become crooked because of scoliosis, but he really tried his best.”
Leeteuk developed this condition after getting in a car accident. Scoliosis is usually not a serious threat to the patience health.
