Photos: 'World's heaviest teenager' finally walks after over 3 years of being stuck in bed

Khaled Mohsen Al Shaeri, once called the "World's Heaviest Teenager," is seen walking for the first time in years in a new video posted by the Sun.

Shaeri lost 700 lbs after being airlifted out of his Saudi Arabian home in August 2013 on the orders of the late King Abdullah, who financed his medical treatment. As at when he was airlifted, he weighed a massive 1,345 lbs at the age of 17 and hadn't left his bed in three years according to the report by The Sun..

 A custom wheelchair helped him start to become more mobile, and Shaeri, once called the ‘world’s heaviest teenager’ built up slowly to the proud moments on the video.
Doctors say he is now more cheerful, happy and lively compared to how he was before he was admmited.
