Anorexia nervosa is an eating disorder and mental health condition that can be life-threatening.
People with anorexia try to keep their weight as low as possible, usually by restricting the amount of food they eat. They often have a distorted image of themselves, thinking that they're fat when they're not.
Some people with the condition also exercise excessively, and some eat a lot of food in a short space of time (binge eating) and then make themselves sick or use laxatives (purging).
People affected by anorexia often go to great attempts to hide their behaviour from family and friends by lying about eating and what they have eaten, or by pretending to have eaten earlier.
