Learn about suicide warning signs

A person who is thinking about suicide will usually give some clues or suicide signs to those around them that indicate they are distressed. These are often referred to as suicide warning signs.

Suicide prevention starts with recognising these suicide warning signs and taking them seriously.

The following is a list of signs that people might give when they are feeling anguished and overwhelmed, in order to communicate their distress to others. These physical changes and behaviours are indicators that a person might be thinking about suicide. Some of these signs are stronger indicators that a person may be thinking about suicide than other – these have been highlighted. It is most likely that a suicidal person will display a combination of these signs rather than one single sign.

Responding to suicide signs

Speak up if you are worried

Talking to a friend or family member about their suicidal thoughts and feelings can be extremely difficult. But if you’re unsure whether someone is suicidal, the best way to find out is to ask.

Sometimes people are worried that they might ‘put the idea of suicide into the person’s head’ if they ask about suicide.

You can’t make a person suicidal by showing that you care.

In fact, giving a suicidal person the opportunity to express his or her feelings can provide relief from loneliness and pent-up negative feelings, and may prevent a suicide attempt.


Ways to start a conversation about suicide

  • I have been concerned about you lately
  • I wanted to check in with you because you haven’t seemed yourself lately.


Questions you can ask the person

  • How can I best support you right now?
  • How long have you been feeling this way?


What you can say that helps

  • You are not alone in this. I’m here for you
  • I may not be able to understand exactly how you feel, but I care about you and want to help

Assess the risk of suicide

If a friend or family member tells you that he or she is thinking about suicide, it is important to evaluate the risk.

Those at the highest risk will have the INTENTION to end their life; a specific PLAN, the MEANS and a TIME-FRAME.

The following questions can help you assess the person’s risk:

  1. Do you intend to take your life? (INTENTION)
  2. Do you have a plan to take your life? (PLAN)
  3. Do you have access to the means to carry the plan out? (pills, gun, etc) (MEANS)
  4. Do you have a time-frame for taking your life? (TIME-FRAME)

If the person is at high risk of suicide, seek immediate help by calling 000 (police, ambulance), or, with their permission take the person to hospital.

Find out what services are available.

This should include local emergency services, community health services and hospitals.
