What Causes Suicide?

A lot of things can contribute to someone having suicidal thoughts and behaviors. For most people, there is not one clear cause. There are some things that can make someone more vulnerable to the distress and hopelessness that can lead to considering suicide, but they don’t cause suicide directly. 

Things that can influence suicidal thoughts and behaviors include:

  • Genetics
  • Early childhood experiences
  • Family environment
  • Mental health outlook, or how someone perceives things to be improving or worsening
  • Mental illness, including major depressive disorder and PTSD
  • Willingness to seek help
  • Coping skills
  • Support networks
  • Stressors and life challenges
  • Trauma history
  • History of bullying or stressful peer relationships
  • Substance misuse 
  • Losing someone you know to suicide 
  • Exposure to storylines in TV shows and films that feature suicide

Are Certain Groups More at Risk for Suicide?

Like any mental health issue, anyone can experience suicidal thoughts and behaviors. Among teens and young adults, research shows that some groups are more likely to have suicidal thoughts, engage in suicidal behaviors, and attempt suicide.

  • Someone who has attempted suicide in the past or has a family history of suicide is at a higher risk for future attempts.
  • Young people who identify as LGBTQ and face hostile environments at school or home, or who experience rejection from their families, are more likely to consider suicide.
  • Women and girls are more likely to attempt suicide, while boys and men are more likely to die by suicide. In part, that’s because of the means of suicide: Men typically choose more violent methods than women do.
