Suicide facts

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

There are different terms used when talking about suicide:

  • 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 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 may 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
  • Mental illness, 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 illness for those with a chronic illness or medical condition are greater than those without chronic illness. If you or someone you know has a chronic health condition, knowing the warning signs is valuable.4

Warning signs

According to recent studies, nearly 5 percent of American adults over the age of 18 have had suicidal thoughts. Some warning signs of suicide include:2,5,6

  • Aggressive behavior
  • Social withdrawal and isolation
  • Increase in risk taking, impulsive, or reckless behavior
  • Threats or comments about wanting to die
  • Talking about feeling hopeless or having no purpose
  • Severe mood swings
  • Increase or new drug use
  • Putting affairs in order
  • Giving away possessions
  • Talking or writing about death
  • Efforts to find needed tools like toxins, weapons, or firearms
  • Saying goodbye to friends and family
  • A switch from highly emotional moods to calm (this could suggest the person is no longer worried about their struggles due to a suicide plan)
