Self-harm describes when someone deliberately damages or hurts their own body. It is associated with a sense of personal distress that can stem from strong emotional reactions such as grief, loss or low self-esteem. Research suggests it is most common among 15 to 19 year olds and people suffering from depression or anxiety. A person may cut, burn, punch, or poison themselves. They may also abuse alcohol or drugs, starve themselves, purge or binge eat – as in cases of anorexia or bulimia. Self-harmers often keep their actions secret and may be at risk of serious injury.
