Depression
Last Updated on June 2, 2025 by Alex Demn
Depression is a common but serious mental health disorder that negatively impacts how a person feels, thinks, and acts. It can lead to a variety of emotional and physical problems and reduce a person’s ability to function in daily life. Unlike temporary sadness, clinical depression is persistent and often requires treatment.
What Causes Depression?
Depression is a multifactorial condition, meaning it can arise from a combination of biological, psychological, and environmental factors. Common causes include:
- Genetic predisposition (family history of depression)
- Chemical imbalances in the brain (neurotransmitters like serotonin and dopamine)
- Traumatic events (abuse, loss, chronic stress)
- Chronic medical conditions (e.g., diabetes, chronic pain)
- Substance abuse
- Hormonal changes (e.g., postpartum depression)
Signs and Symptoms of Depression
Symptoms of depression vary by individual but often include:
- Persistent feelings of sadness or hopelessness
- Loss of interest or pleasure in activities once enjoyed
- Changes in appetite or weight
- Sleep disturbances (insomnia or excessive sleeping)
- Fatigue or low energy
- Difficulty concentrating or making decisions
- Feelings of worthlessness or excessive guilt
- Thoughts of death or suicide
If symptoms persist for two weeks or more, it’s important to seek professional help.
Side Effects and Complications
If untreated, depression can lead to:
- Poor work or academic performance
- Relationship problems
- Social withdrawal
- Substance misuse
- Chronic health conditions worsening
- Increased risk of suicide
Depression is also linked to an increased risk of heart disease, obesity, and weakened immune function.
How Is Depression Treated?
Treatment often involves a combination of approaches tailored to the individual:
- Psychotherapy: Cognitive-behavioral therapy (CBT), interpersonal therapy (IPT), and other talk therapies.
- Medication: Antidepressants like SSRIs and SNRIs can help regulate brain chemistry.
- Lifestyle changes: Regular physical activity, improved diet, and quality sleep can improve symptoms.
- Mindfulness and stress-reduction techniques: Meditation, yoga, and journaling.
- Support networks: Family support, peer groups, or online communities.
Prevention and Coping Strategies
While not all cases of depression are preventable, certain practices may help:
- Maintain strong social connections
- Stay physically active
- Practice gratitude and mindfulness
- Set realistic goals and manage expectations
- Seek professional help early if symptoms arise

Professional intervention is crucial if:
