Body Shock Season 4, Episode 1: The Boy in the Bubble

Half man, half tree

World's Biggest Boy

At just seven years old Dzhambulat Khatokhov ('Jambik' for short) is four foot three inches tall and weighs 16 stone - as much as a baby elephant. He dwarfs his older brother who is twice his age and less than half his weight. Nobody knows why Jambik is so big, or what this means for his long-term health. But Dr Campbell - one of the world's leading experts on obesity - is determined to find out. Travelling over 2000 miles to the Caucasus Mountains in Southern Russia, Campbell meets the 'biggest boy in the world' to see what, if anything, can be done for him...

The Girl With 8 Limbs

For a few weeks in 2007 she was the most famous little girl in the world. Lakshmi Tatma was the girl with eight limbs, born with one of the world's rarest physical abnormalities. Joined at the pelvis to her half-formed twin, she had four arms and four legs. In her remote Indian village she was revered as a living god. Bodyshock had exclusive access to follow Lakshmi and her family through the life-threatening surgery to remove her extra limbs.
