Suicidal Ideation



Thinking about, considering, or planning to commit suicide is known as suicidal ideation.


Suicide is often the result of many factors which can vary from person to person. Many people thinking about suicide are having difficulty coping with stressful factors and feel very overwhelmed and hopeless.

The majority of people who consider suicide also have a mental illness like depression or substance abuse. These conditions may cause suicidal thoughts alone or simply make stressful situations worse.

People who are thinking about suicide may:

  • Talk about wanting to die or commit suicide
  • Talk about feelings of despair
  • Plan for death, such as giving away favorite items
  • Withdraw from family and friends

Other symptoms may include:

  • Irritability
  • Indifference
  • Difficulty focusing
  • Loss of interest in daily activities, such as work and hobbies
  • Loss or gain in appetite
  • Sleeping too little or too much
  • Changes in appearance, such as lack of personal hygiene
  • Increased use of alcohol or drugs
  • Mood swings that range from irritability to a sudden sense of calm
  • Acting anxious or restless; behaving hastily
  • Talking about feeling trapped or in unbearable pain

These symptoms can occur without suicidal ideation. However, if someone you know has these signs, try to talk to them to better learn what is happening. Asking about suicidal feelings will not encourage someone to commit suicide but may actually help prevent suicide.

If you or someone you know has thoughts of suicide or harming oneself, it is important to seek professional help right away. There are many suicide hotlines to help those considering suicide or to provide information for friends and family of someone considering suicide.

If the risk of suicide is severe, go to an emergency room or call for emergency services. Risk is considered severe if the person has a well thought out plan to commit suicide and has access to items that can cause harm.


The doctor will ask about symptoms and medical and psychiatric history. Family members may also be interviewed.

A mental health specialist may complete a psychological assessment to look for any underlying issues.



Immediate hospitalization may be needed if there is a severe threat of suicide.

Individual, family, and/or group therapy will be used to help manage suicidal thoughts.

Overall treatment goals include:

  • Care for underlying mental, physical, and substance abuse disorders
  • Limiting access to items that may be used for self-harm
  • Developing a support system that includes family members and friends
  • Developing skills in problem solving, conflict resolution, and handling problems through nonviolent means


To help reduce your risk of suicidal ideation:

  • Follow treatment plans for mental or physical health disorders that you may have.
  • Avoid drugs and alcohol. If you have problems with substance abuse, talk to your doctor.
  • If you have difficulty coping with a stressor, talk to someone you trust, such as a family member, friend, or therapist.
  • Limit access to items that may be used for self-harm.
