More than 750,000 people in the UK are affected by an eating disorder – but what happens when you’re a type 1 diabetic and misuse insulin in order to dramatically lose weight? In this documentary produced by BBC Three and BBC Newsbeat, we meet three young sufferers who are risking their eyesight, limbs, fertility and lives in order to be thin. We follow one young girl whose parents know she’s skipping her insulin but are struggling to understand the mental health aspect of her condition; a young mum who is not receiving the appropriate healthcare due to the lack of awareness and expertise on how to treat diabulimia; and a young woman who was saved from the brink of death and is now beginning to rebuild her life, despite the illness leaving her with physical disability.
