Understanding the Link Between Self-Harm and Suicide
Updated: Jul 29
Self-harm and suicide are two deeply concerning mental health issues in the UK that often intersect in complex ways. While not everyone who self-harms is suicidal, self-harm can be a significant risk factor for future suicide attempts. Understanding this connection is essential for providing the right support, reducing stigma, and encouraging early intervention.
The Statistics
According to data from the UK’s Office for National Statistics (ONS) and mental health charities:
Around 200,000 people are treated in A&E departments each year following self-harm episodes.
People who self-harm are 50 times more likely to die by suicide than those who do not.
Suicide remains the leading cause of death for people aged 20 to 34 in the UK.
These numbers highlight the importance of recognising self-harm not just as a coping mechanism, but as a red flag for deeper mental health challenges.
Understanding the Connection
Self-harm is often used as a way to manage overwhelming emotions, psychological distress, or a sense of numbness. While it’s not always linked to suicidal intent, the behaviours can escalate. People who repeatedly self-harm may become desensitised to pain, increasing the likelihood of accidental or intentional suicide.
Risk factors include:
Past trauma or abuse
Mental health conditions (e.g. depression, anxiety, BPD)
Substance misuse
Social isolation
Lack of access to mental health care
Early intervention is critical to break this cycle and prevent harm from escalating.
There Is Hope: Positive Outcomes
Despite the serious risks, many people recover from self-harm and suicidal thoughts with the right support. Increased awareness, mental health education, and funding for services have contributed to more people reaching out for help. Schools, employers, and healthcare professionals are increasingly trained to recognise the signs of self-harm and intervene earlier.
Therapies such as Cognitive Behavioural Therapy (CBT), Dialectical Behaviour Therapy (DBT), and Trauma-Informed Care have shown positive outcomes. Peer support groups and online communities also offer connection and understanding to those in distress.
