Hello doctor, what are suicidal thoughts and what causes such thoughts? Alex

Dear Alex, that is called suicidal ideation

It refers to the presence of recurring passive or active thoughts of self-harm or suicide. These thoughts are commonly associated with mental health conditions such as depression.

They may include feelings that life is not worth living, a desire to cause harm to oneself, or making (or not making) plans to act on such thoughts.

Types of suicidal ideation

  • Passive suicidal ideation: Thoughts of not wanting to live, without any intention or plan to act on them.
  • Active suicidal ideation: Thoughts of suicide accompanied by an intention or a plan to act. Some people may withdraw socially or feel a temporary sense of relief after making a plan.

Suicidal thoughts rarely occur in isolation. They are often linked to symptoms such as persistent low mood, loss of interest in pleasurable activities, fatigue, poor concentration, low self-esteem, excessive guilt, sleep disturbance, appetite changes, or feelings of agitation.

Causes of suicidal thoughts

1. Genetics

  • Higher risk if a first-degree relative has experienced depression.
  • Twin studies suggest heritability of 40–50 per cent for identical twins, 20 per cent for fraternal twins.
  • Adoption studies show increased risk even without a direct family history.

2. Organic causes

  • Physical illnesses, especially endocrine disorders.
  • Certain medications, such as corticosteroids, oral contraceptives, beta-blockers, clonidine, metoclopramide, theophylline, and nifedipine.

3. Psychosocial factors

  • Adversity in childhood: parental loss, poor bonding, inadequate or overprotective care, physical or sexual abuse.
  • Adversity in adulthood:
    • For women: lack of a confiding relationship, caring for more than three young children.
    • For men: unemployment, divorce, or loss of custody.
  • Recent life events: bereavement, divorce, marital separation, imprisonment, unemployment, or the death of a close relative.

4. Cognitive errors

  • Magnification: Exaggerating the significance of a failure and ignoring past successes.
  • Overgeneralisation: Extending failure in one area of life to all other areas.
  • Personalisation: Believing one is entirely to blame for failures, disregarding external factors.

Treatment

  • Counselling and supportive therapy can be effective for mild cases.
  • Sleep hygiene advice may help when sleep disturbance is a problem.
  • Hospitalisation may be required if there is high risk of self-harm. In such cases, treatment may include antidepressant medication alongside therapy.

Please seek counselling or therapy in case you are experiencing such thoughts.
