What is Anorexia?

Anorexia is an eating disorder and serious mental health condition. People who have anorexia try to keep their weight as low as possible by not eating enough food or exercising too much, or both. This can make them very ill because they start to starve.

They often have a distorted image of their bodies, thinking they're fat even when they're underweight. Men and women of any age can get anorexia, but it's most common in young women and typically starts in the mid-teens.

Signs and symptoms

Anorexia

  • If you're under 18, your weight and height being lower than expected for your age

  • If you're an adult, having an unusually low body mass index (BMI)

  • Missing meals, eating very little or avoiding eating any foods you see as fattening

  • Believing you're fat when you're a healthy weight or underweight

  • Taking medicine to reduce your hunger (appetite suppressants)

  • Your periods stopping (in women who have not reached menopause) or not starting (in younger women and girls)

  • Physical problems, such as feeling lightheaded or dizzy, hair loss or dry skin

Some people with anorexia may also make themselves sick, do an extreme amount of exercise, or use medicine to help them poo (laxatives) or to make them pee (diuretics) to try to stop themselves gaining weight from any food they do eat.

What is Bulimia?

People who have bulimia go through periods where they eat a lot of food in a very short amount of time (binge eating) and then make themselves sick, use laxatives (medicine to help them poo) or do excessive exercise, or a combination of these, to try to stop themselves gaining weight.

Bulimia is an eating disorder and mental health condition. Anyone can get bulimia, but it is more common in young people aged 13 to 17.

Signs and symptoms

Bulimia

  • Eating very large amounts of food in a short time, often in an out-of-control way – this is called binge eating

  • Making yourself vomit, using laxatives, or doing an extreme amount of exercise after a binge to avoid putting on weight – this is called purging

  • Fear of putting on weight

  • Being very critical about your weight and body shape

  • Mood changes – for example, feeling very tense or anxious

These symptoms may not be easy to spot in someone else because bulimia can make people behave very secretively.
