<unk> , or KLS, is an extremely rare disorder characterized by the need for excessive amounts of sleep (hypersomnia), (e.g. up to 20 hours a day); excessive food intake (compulsive hyperphagia); and an abnormally uninhibited sexual drive. Adolescent males and females are the predominant victims of the disorder. There are only about 500 known sufferers of this condition in the world. However, because KLS is sporadic in its appearances, some doctors believe that this number is, in reality, much higher and the reason that it is not publicly noted is because this disease is extremely difficult to diagnose.
