Self-mutilation or self-injury is any form of self-harm inflicted on your body without the intent to commit suicide. Self-mutilation may be performed to release emotional pain, anger, or anxiety; to rebel against authority; to flirt with risk-taking; or to feel in control. In some cases, the behavior is outside your emotional control and related to a neurological or metabolic disorder.

The behavior is not considered socially appropriate. It is also not part of a religious custom or a form of art.

Self-mutilation is a severe impulse control disorder that is often associated with other psychiatric disorders, such as:

• Borderline personality disorder
• Depression
• Substance abuse, such as alcoholism or drug abuse
• Eating disorders, such as anorexia or bulimia
• Psychosis
• Antisocial personality disorders
• Post-traumatic stress disorder

Self-mutilation is often associated with psychiatric disorders that may be caused by chemical imbalances in the brain.

It can also be associated with neurologic or metabolic disorders such as:

• Tourette syndrome —a neurological disorder
• Autism —a disorder that results in social, behavioral, and language problems
• Lesch-Nyhan syndrome —a genetic disorder

Factor that increase your chance of developing this condition include:

• Childhood sexual, physical, or emotional abuse
• Violence or other abusive relationships in a child's home
• Post-traumatic stress disorder
• Being in prison
• Sex: female
• Age: adolescence
• Intellectual disability
• Autism
• Certain metabolic disorders

The symptoms of self-mutilation vary. The most common symptoms include:

• Cutting of skin with a sharp object
• Skin carving or burning
• Self-punching or scratching
• Needle sticking
• Head banging
• Eye pressing
• Finger, lips, or arm biting
• Pulling out one's hair
• Picking at one's skin

Rarely, in very severe cases, self-mutilation can include:

• Broken bones
• Amputation
• Castration
• Suicide

Self-mutilation can be difficult to diagnose. People who self-mutilate often feel guilty and ashamed about their behavior. They may try to hide it. Physical harm caused by self-multilation may be the first sign noticed during an exam. To be diagnosed, symptoms should meet the following criteria:

• Excess concern with physically harming oneself
• Inability to resist harming oneself, resulting in tissue damage
• Increased tension before and a sense of relief after self-injury
• Having no suicidal intent in the self-mutilation

To make an accurate diagnosis, the psychologist or psychiatrist will assess other conditions, like personality or mood disorders, and whether there is suicidal intent.

Treatment usually includes medical and psychological treatment, as well as medications.

The best prevention is to get help as soon as possible for depression, trauma, emotional problems, or other disorders that may lead to self-mutilation.
