Suicide: Understanding the Causes, Signs, and Prevention Strategies
Suicide is a global public health crisis and one of the leading causes of death worldwide. Each year, nearly 800,000 people die by suicide, and many more attempt it. Despite its prevalence, suicide is often stigmatized, misunderstood, or ignored. To effectively prevent it, we must understand the underlying factors, recognize warning signs, and build supportive environments that promote mental health and resilience.
What Is Suicide?
Suicide is the intentional act of ending one’s own life. It is typically the result of intense psychological pain, feelings of hopelessness, or a perceived lack of options. Suicide does not occur in a vacuum—many individuals struggling with suicidal thoughts are experiencing mental illness, trauma, social isolation, or overwhelming life stressors.
There are three commonly discussed terms:
- Suicidal ideation: Thinking about or planning suicide
- Suicide attempt: Non-fatal, self-directed behavior with intent to die
- Completed suicide: A fatal outcome from intentional self-harm
Causes and Risk Factors
Suicide is complex and often results from a combination of risk factors:
- Mental Health Disorders
- Depression, bipolar disorder, schizophrenia
- Substance use disorders
- PTSD or anxiety disorders
- Psychological Factors
- Hopelessness
- Impulsivity
- History of trauma or abuse
- Social and Environmental Stressors
- Relationship problems or loss
- Financial difficulties

- Access to lethal means (e.g., firearms, poisons)

Warning Signs of Suicide
Recognizing warning signs can save lives. Common indicators include:
