At 5′6″ and 34 stone, Bethany weighed three times the size of an average 19-year-old and was the largest teen in the UK. In a desperate, last-ditch attempt to save her life and restore her body image, Bethany decided to undergo potentially fatal surgery with an operation to remove two-thirds of her stomach and drastically reduce the amount of food she can eat.

The teenager’s story was told in a moving documentary last autumn as part of the critically acclaimed Body Image Season, which gave BBC Three its highest-ever weekly reach.

The season returns this month with a series of new, one-off documentaries, aired over two weeks, examining people’s obsession with their bodies and the way they look, and including an update on Bethany’s story six months on.

This programme revisits Bethany’s story and asks if the surgery she has undergone has been the answer to her prayers. Surgery may have shrunk her stomach but a question remains over whether her relationship with food has changed.
