Suicide facts

Suicide is among the leading causes of death in the United States. For people ages 10 to 34 in the United States, suicide is the second leading cause of death.2

Experts use several different terms to talk about suicide:2

  • Suicide is death caused by self injury with the intent to die as a result of the action.
  • A suicide attempt is also caused by self injury, but it is not fatal. An attempt may or may not result in injury.
  • Suicidal ideation includes thoughts of suicide.

Risk factors

A combination of factors may lead to someone considering suicide. Known risk factors for suicide include:3

  • A family history of suicide
  • Previous suicide attempts
  • Legal problems
  • Job problems or loss
  • Access to drugs or guns
  • A chronic illness or medical condition
  • Drug or alcohol use disorder
  • A mental health condition, such as depression
  • Bullying
  • A personal history of abuse or trauma
  • Chronic stress
  • Recent loss

Suicide is an important and often neglected subject for people with chronic illness. Research shows that rates of mental health conditions for those with a chronic illness or medical condition are greater than for those without chronic illness. If you or someone you know has a chronic health condition, knowing the warning signs is valuable.4
