North Korean leader Kim Jong-un is currently suffering from insomnia, as well as diseases caused by obesity, South Korea's intelligence agency said Friday, adding he has gained 40 kilograms over the past four years, the Yonhap reported.

The National Intelligence Service (NIS) said in its report to a meeting of the parliament's intelligence committee that Kim is presumed to weigh 130 kilograms, a jump from 90 kilograms when he took office in 2012.

Rep. Lee Cheol-woo of the ruling Saenuri Party, who chairs the committee, said Kim is currently under great stress due to his safety, which has led to excessive binge eating and drinking.
