A woman who at one point had become so thin she broke her rib just by hugging her rib just by hugging her boyfriend has opened up about her struggle with anorexia in a bid to help others living with eating disorders.

18-year-old Georgia McGrath, who weighed just five stone at her lowest weight and is now back to a healthy weight for a woman of her size, says that moment was the trigger on her road to recovery:

Just as he caught me, his shoulder went into my chest there, and it was horrible, it was like, at first it felt like stitch up here because I couldn't breathe and then I could't move anything. I can't explain the pain, and actually the pain actually gets worse as it's healing.

Surviving on less than 100 calories a day - Georgia had become obsessed with her size - after girls at school called her fat. She dropped half her bodyweight, eating virtually nothing and spending more and more of her time in the gym.

Even when I was just five stone I wanted to lose weight. I desperately wanted to lose weight."

The NHS describes Anorexia nervosa is a "serious mental health condition" - an eating disorder where a person keeps their body weight as low as possible.

People with anorexia usually do this by restricting the amount of food they eat, making themselves vomit, and exercising excessively.

The condition often develops out of an anxiety about body shape and weight that originates from a fear of being fat or a desire to be thin. Many people with anorexia have a distorted image of themselves, thinking they're fat when they're not.

Anorexia: Things to look out for

  • missing meals, eating very little, or avoiding eating any fatty foods

  • obsessively counting calories in food

  • leaving the table immediately after eating so they can vomit

  • taking appetite suppressants, laxatives, or diuretics

  • repeatedly weighing themselves or checking their body in the mirror

  • dizziness hair loss, or dry skin

Anorexia most commonly affects girls and women, although it has become more common in boys and men in recent years. On average, the condition first develops at around the age of 16 to 17.

People with anorexia often go to great lengths to hide their behaviour from family and friends by lying about what they've eaten or pretending to have eaten earlier.

Georgia, from Hull, admits there are times when she still struggles with food. And despite being back to a healthy weight - she knows the damage to her body is far more long lasting.

There's still a lot of health implications when you recover. A lot of these things stay with you so with me, my heart now is very unstable, and was I to do exercise, it might affect it.

She is now writing about her experience - hoping her book will educate others - whose desperation to be thin - is driving them to put their lives at risk.
