Self-harm or deliberate self-harm includes self-injury and self-poisoning and is defined as the intentional, direct injuring of body tissue most often done without suicidal intentions. The most common form of self-harm is skin-cutting but self-harm also covers a wide range of behaviors including, but not limited to, burning, scratching, banging or hitting body parts, interfering with wound healing, hair-pulling (trichotillomania) and the ingestion of toxic substances or objects. Although suicide is not the intention of self-harm, the relationship between self-harm and suicide is complex, as self-harming behaviour may be potentially life-threatening. Learn more about self-harm, its various causes, prevention and treatment in this book.
