Causes & Symptoms of Self-Injury

Self-harming behaviors occur when someone purposely and intentionally inflicts some form of pain onto him or herself. Such behaviors can include cutting, burning, or biting oneself, pulling out one’s hair, banging one’s head against a hard object, or punching oneself. While not necessarily as common, some people will injure themselves by purposely drinking harmful substances like bleach, detergent, or other household chemicals, or by purposely breaking their own bones.

One common misconception about self-harm is that people are participating in such acts as a means of ending their own lives. Typically, this is not the case. The majority of individuals who purposely injure themselves do so as a means of dealing with an inner sense of emotional turmoil that is so powerful that they cannot find any other way to cope with it. By inflicting physical pain onto themselves, these people are able to control the pain they are feeling, giving them back the sense of control that they lost through their emotional pain.

Other individuals will use self-mutilation in order to ground themselves in reality. For example, people who suffer from dissociative episodes or feelings of depersonalization and derealization often use self-harm as a way to forcefully make themselves return to the world around them. The physical pain provides them with something tangible to focus on.

Regardless of the reason or reasons why an individual begins harming him or herself, it is a behavior that requires immediate treatment because even if the person does not start the behavior with the intention of committing suicide, the line between self-injury and making an actual suicide attempt can be crossed at any time.

Statistics

The act of self-harm is something that is most commonly done in private, which makes it difficult to compile any exact statistics on the true prevalence of how often these behaviors occur or how many people are participating in them. However, results from different studies have shown that approximately 10% of teenagers between the ages of 12 and 19 have experimented with self-mutilation. Additional estimates state that 1 in every 200 girls between the ages of 13 and 19 engage in self-harming behaviors on a regular basis.

Causes and Risk Factors of Self-Harm

Professionals in the field agree that the contributing factors that can ultimately lead a person to start harming him or herself are a compilation of genetic, physical, and environmental factors, as described in the following:

Genetic: Self-injury is often symptomatic of the presence of a mental health disorder, and these types of disorders are known to have a strong genetic component. For example, disorders such as bipolar disorder, anxiety disorders, and depressive disorders are all known to run in families and all may lead to the onset of self-harming behaviors. Therefore, individuals who have family members who struggle with mental illnesses are likely to be at a higher risk for beginning to participate in self-mutilating behaviors.

Physical: The brain consists of neurotransmitters that are responsible for appropriately regulating emotions. When these neurotransmitters suffer an imbalance, an individual becomes more susceptible to developing a mental disorder, which can then lead to the onset of self-injurious behaviors.

Environmental: The environment in which children and adolescents spend a great deal of time can have a momentous impact on whether or not they will begin to self-harm. Individuals who grow up in chaotic or violent homes may turn to self-harm as a way of gaining a sense of control over themselves because they are unable to control anything else in their lives. Similarly, individuals who have been made victims of abuse may begin self-injuring as a means of numbing themselves from the residual pain of their experiences.

Risk Factors:

  • Being female
  • Being in the age group of adolescents, teens, and young adults
  • Personal history of depression or other mental illness
  • Family history of mental illness
  • Having friends or family members who self-harm
  • Lacking appropriate coping skills
  • Experiencing trauma
  • Lacking the ability to regulate one’s emotions
  • Lacking strong, healthy interpersonal relationships
  • Experiencing the death or loss of a loved one

Signs and Symptoms of Self-Harm

The signs and symptoms that may be exhibited by an individual who is self-injuring can vary greatly from person to person.
