Suicide Causes, Warning Signs & Treatment

Suicide: Causes, Warning Signs, Prevention and Treatment — A Psychiatrist’s Guide

By Dr. Muhammad Shoaib Zafar, Psychiatrist, Addiction Specialist & Child and Adolescent Psychiatrist

Suicide is one of the most serious and preventable public-health challenges facing individuals, families and communities worldwide. It can affect people of any age, background or social status. Importantly, suicidal thoughts are not a sign of weakness or a character flaw. They can occur when psychological pain, mental illness, trauma, substance use, social stress and other factors become overwhelming.

With timely assessment, appropriate psychiatric treatment, psychological therapy, family support and safety planning, many people experiencing suicidal thoughts can recover and regain hope.

If you or someone you know is in immediate danger, has recently attempted suicide, or feels unable to stay safe, seek emergency medical help immediately and do not leave the person alone.

Suicide: Global Facts and Statistics

According to the World Health Organization (WHO), more than 720,000 people die by suicide every year worldwide. Suicide was the third leading cause of death among people aged 15–29 years globally in 2021. Approximately 73% of global suicides occur in low- and middle-income countries. (World Health Organization)

WHO also reports that for every suicide death, there are many more suicide attempts. Its current estimates indicate that there may be more than 20 attempts for every suicide death, although the ratio varies substantially between countries and populations. (World Health Organization)

These figures demonstrate why suicide prevention cannot be addressed only after a crisis occurs. Early recognition, access to mental-health care and effective prevention strategies are essential.

Suicide in Pakistan

Understanding suicide in Pakistan is particularly challenging because reliable national suicide surveillance and death-registration data remain limited.

WHO’s country data currently reports a suicide mortality rate of approximately 6.09 per 100,000 population for Pakistan in 2019, with a wide uncertainty interval. WHO also cautions that mortality estimates for Pakistan should be interpreted carefully because the country’s death-registration data are incomplete or of insufficient quality for some purposes. (World Health Organization)

WHO’s Mental Health Atlas 2020 reported an age-standardized suicide mortality estimate of 9.77 per 100,000 population for Pakistan in 2019, illustrating why figures can differ depending on the methodology, year and source used. (WHO)

Recent research continues to highlight the limitations of Pakistan’s suicide data. A 2026 scoping review found that the absence of a comprehensive national suicide surveillance system makes it difficult to determine the true scale of suicidal behaviour in Pakistan. (PubMed Central (PMC))

Therefore, it is important to avoid presenting any single Pakistani figure as an exact count of all suicides. Under-reporting, stigma, differences in classification and incomplete registration can substantially affect available statistics.

What Causes Suicide?

There is rarely one single cause of suicide.

Suicidal behaviour usually develops through a complex interaction of psychological, biological, social, environmental and situational factors.

Some people may experience suicidal thoughts during a severe depressive episode. Others may reach a crisis after relationship difficulties, financial problems, bereavement, trauma, chronic illness, substance use or an overwhelming life event.

WHO emphasizes that suicide has multifactorial causes and can occur during periods of acute crisis, including situations where a person’s ability to cope with severe stress temporarily becomes overwhelmed. (World Health Organization)

Mental health conditions associated with suicide risk

Mental-health disorders can significantly increase suicide risk, particularly when they remain untreated.

Conditions that may be associated with suicidal thoughts or behaviour include:

* Major depressive disorder * Bipolar disorder * Schizophrenia and other psychotic disorders * Severe anxiety disorders * Post-traumatic stress disorder (PTSD) * Borderline personality disorder and severe emotional dysregulation * Substance-use disorders * Alcohol-use disorder * Severe eating disorders * Some chronic pain and medical conditions

Depression deserves particular attention. WHO estimates that approximately 332 million people worldwide live with depression, and depression can be associated with suicidal thoughts and suicide. (World Health Organization)

Social and psychological factors

Suicide risk may also increase in association with:

* Loss of a loved one * Relationship breakdown or interpersonal conflict * Loneliness and social isolation * Financial difficulties * Academic or occupational pressure * Domestic violence or abuse * Childhood trauma * Bullying * Chronic pain or serious illness * Legal or social crises * Discrimination * Major life transitions * Conflict, displacement or humanitarian emergencies

These factors do not automatically cause suicide. Many people experience severe adversity without becoming suicidal. Risk depends on the individual and the interaction between their circumstances, mental health, coping resources and available support.

Substance Use and Suicide Risk

Alcohol and other psychoactive substances can increase suicide risk in vulnerable individuals.

Substance use may:

* worsen depression and anxiety * increase impulsivity * impair judgment * intensify interpersonal problems * reduce inhibitions during a crisis * interfere with psychiatric treatment * increase the likelihood of acting on suicidal thoughts

This is particularly important when suicidal thoughts occur alongside alcohol dependence, opioid dependence, stimulant use or other substance-use disorders.

For this reason, suicide risk assessment should be an integral part of addiction and psychiatric care.

Warning Signs of Suicide Risk

A person considering suicide may not always openly say, “I want to die.”

Possible warning signs include:

* Talking about death or suicide * Saying that life is no longer worth living * Expressing hopelessness or feeling like a burden * Severe withdrawal from family or friends * Sudden major changes in mood or behaviour * Giving away valued possessions * Saying goodbye in an unusual way * Severe agitation, anxiety or emotional distress * Increasing alcohol or drug use * A previous suicide attempt or episode of self-harm * Sudden deterioration in functioning * Seeking access to potentially lethal means * Saying that others would be better off without them

A particularly important risk factor is a previous suicide attempt. WHO identifies previous attempts as an important risk factor for suicide. (World Health Organization)

What Should You Do If Someone Talks About Suicide?

Take the person seriously.

Do not dismiss suicidal thoughts with statements such as:

* “You are just seeking attention.” * “Think about your family.” * “Other people have bigger problems.” * “You should be grateful.” * “You will get over it.”

Instead:

1. Listen calmly

Give the person an opportunity to speak without immediately judging, arguing or lecturing.

2. Ask directly about safety

It is appropriate to ask whether the person is thinking about suicide or feels unable to keep themselves safe. Asking about suicide does not create suicidal thoughts.

3. Do not leave an acutely suicidal person alone

If there is immediate danger, arrange urgent professional or emergency assistance.

4. Reduce access to potentially lethal means

Where safe and appropriate, increase supervision and reduce access to items or substances that could be used for self-harm.

5. Connect the person with professional care

A psychiatrist or other qualified mental-health professional can assess the level of risk and determine the appropriate treatment setting.

How Is Suicidal Behaviour Treated?

Suicidal thoughts are a clinical emergency when accompanied by imminent risk, but they are also a treatable symptom of underlying psychological or psychiatric distress.

Treatment depends on the individual’s diagnosis, risk level, circumstances and support system.

Psychiatric assessment

A comprehensive psychiatric assessment may evaluate:

* Current suicidal thoughts * Previous attempts or self-harm * Depression and anxiety * Bipolar symptoms * Psychotic symptoms * Substance use * Trauma * Personality and emotional regulation * Medical conditions * Current medications * Social and family circumstances * Protective factors and available support

The goal is not simply to ask whether someone is suicidal. The clinician needs to understand why the person is experiencing suicidal thoughts and what level of intervention is required.

Psychotherapy

Evidence-based psychological therapies can play an important role in reducing suicidal thinking and suicidal behaviour.

Depending on the individual, treatment may include:

* Cognitive Behavioural Therapy (CBT) * Dialectical Behaviour Therapy (DBT) * Trauma-focused psychotherapy * Interpersonal approaches * Supportive psychotherapy * Family-based interventions * Treatment focused on emotional regulation and coping skills

Research has found evidence that CBT and DBT can reduce suicidal ideation in selected populations, while DBT has particularly strong evidence for reducing suicidal behaviour in people with significant emotional dysregulation and borderline personality disorder. (PubMed)

Medication treatment

Medication is not a universal treatment for suicidal thoughts by itself. It is generally used to treat the underlying psychiatric disorder when medication is clinically indicated.

Depending on the diagnosis, treatment may involve antidepressants, mood stabilizers, antipsychotic medication or other evidence-based treatments.

For example, evidence supports the role of lithium in reducing suicide risk in some people with mood disorders, while other interventions may be appropriate for specific clinical situations. (PubMed)

Medication should always be prescribed and monitored by a qualified clinician, particularly when suicide risk is present.

Hospital or intensive psychiatric care

Hospital admission or intensive psychiatric treatment may be necessary when a person:

* is at immediate risk of suicide * has recently attempted suicide * cannot maintain their own safety * has severe psychosis or mania * has severe depression * is intoxicated or experiencing significant substance-related risk * lacks adequate supervision or support * requires close medication or medical monitoring

Hospitalization is not a punishment. In an acute crisis, it can provide a safe environment for stabilization and treatment.

Can Suicide Be Prevented?

Yes.

WHO states that suicide is preventable and recommends a comprehensive public-health approach. Effective prevention includes early identification of people at risk, access to appropriate mental-health care, emotional support and interventions that reduce access to highly lethal means during periods of crisis. (World Health Organization)

Prevention also requires addressing broader social factors, reducing stigma and improving access to mental-health services.

Why Early Psychiatric Treatment Matters

One of the most important principles in suicide prevention is not waiting for the crisis to become severe.

Early treatment can help address:

* depression * anxiety * bipolar disorder * psychosis * trauma * substance dependence * insomnia * emotional dysregulation * relationship and adjustment difficulties

Treatment can restore functioning, improve coping skills and help a person develop safer ways of managing overwhelming emotions and life stress.

The objective is not merely to stop suicidal thoughts temporarily. The broader goal is to treat the underlying illness, strengthen psychological resilience and help the individual return to a meaningful and functional life.

Suicide Prevention Requires Families and Communities

Families can play an important role in recovery.

Support may include:

* listening without judgment * accompanying the person to appointments * helping maintain treatment adherence * recognizing early warning signs * encouraging healthy routines * reducing substance use * improving social connection * helping create a safety plan * ensuring urgent help is obtained when risk increases

However, family support should complement—not replace—professional psychiatric care when significant suicide risk is present.

Suicide Is Not a Failure of Character

People experiencing suicidal thoughts are often in severe psychological pain.

Calling them weak, selfish or attention-seeking can increase shame and discourage them from seeking help.

A more helpful approach is to recognize suicidal thinking as a serious clinical and human crisis that deserves compassion, assessment and treatment.

Mental-health treatment is healthcare. Seeking psychiatric help is not a failure.

When Should You See a Psychiatrist?

Consider professional psychiatric assessment if you or someone close to you experiences:

* recurrent suicidal thoughts * thoughts of self-harm * a previous suicide attempt * severe depression or hopelessness * significant mood swings * psychotic symptoms * severe anxiety or panic * trauma-related symptoms * substance dependence * severe insomnia accompanied by emotional deterioration * major deterioration in work, academic or social functioning

If there is immediate danger or a person has already attempted suicide, do not rely on an online appointment or routine consultation. Seek emergency medical care immediately.

A Message from Dr. Muhammad Shoaib Zafar

Suicidal thoughts can make a person feel as though there is no way forward. In psychiatry, we often see that the person’s perception of the future can change significantly when the underlying depression, trauma, addiction, anxiety, psychosis or emotional crisis is properly treated.

There may be a solution even when the person cannot see one at that moment.

The first step is to talk to someone, seek professional help and remain safe through the crisis.

You do not have to face it alone.
