There are many factors which can cause depression, such as:

Genetics and biology:

Studies associated with twins, adoption, and family studies have shown there that there’s a link between depression and genetics. It is believed that if an immediate family member has been diagnosed with depression, your risk of being depressed is higher.

Brain chemistry imbalance:

Depression is believed to be caused by an imbalance of neurotransmitters in our brain. These are chemical substances that help different areas of the brain communicate with each other and are involved in mood regulation. A decreased number of neurotransmitters may cause symptoms of clinical depression.

Circadian rhythm disturbance:

A seasonal affective disorder is believed to be caused by a disturbance in the normal circadian rhythm of the body. Light entering the eye influences this rhythm, and, during the shorter days of winter, when people may spend limited time outdoors, this rhythm may become disrupted.

Unhealthy diet:

A poor diet can cause depression in many ways. Many types of vitamin and mineral deficiencies are known to cause symptoms of depression.

Physical illness:

The mind and the body are linked, which is why a physical illness can cause mental health issues as well. The stress which comes with having a chronic illness can cause depression. Moreover, certain diseases, such as thyroid disorders, Addison’s disease, and liver disease, can cause depression symptoms.
Substance abuse: Use and abuse of alcohol and drugs can cause depression in an individual.

Stress:

Stressful life events may also cause depression. Researchers suspect high levels of the hormone cortisol, which are secreted during periods of stress, may affect the neurotransmitter serotonin and contribute to depression.

Loss of a loved one

When a person goes through the loss of a loved one, grief may turn into depression symptoms such as insomnia, poor appetite, and a loss of pleasure or interest in everyday activities.

Effects of Depression:

The most common effects of depression are:

  • Physical pain such as headache and stomach pain
  • Anxiety
  • Weakened immune system
  • Social isolation
  • Inability to perform at work or school
  • Problems in relationships
