What Causes Depression? 5 Causes & Treatment Options

Depression can be triggered by internal factors (which vary from person to person) and external factors (which are out of a person’s control). It often occurs as a result of genetic, biological, environmental and psychological factors that affect neurotransmitter levels. Serotonin, dopamine and noradrenaline levels are typically noted to be imbalanced in cases of depression. 

It is important for people with depression to be monitored by a psychologist and/or psychiatrist so that the underlying cause of depression is managed. A health care professional can initiate treatment to relieve symptoms and promote quality of life.

1. Bullying or emotional blackmail

People who are victims of bullying or emotional blackmail may experience emotional trauma which can trigger depression. People who are frequently insulted over a long period time may eventually believe that what is said about them is true, which can decrease self worth and lead to depression. 

2. Major life events 

Certain major life events, like a divorce, unemployment, the loss of a loved one, a break-up or other traumatic situations can often cause depression. Situations that are associated with persistent stress, like frequent arguments at home or work, are more likely to contribute to depression, as the prolonged nature of discord can produce feelings of guild, loss of confidence, decreased trust in others and low self-esteem.

3. Serious and chronic illness 

The diagnosis of a serious illness like a stroke, dementia, cancer, HIV, diabetes, irritable bowel syndrome or lupus can cause depression. Many people may struggle with addressing their own preconceptions of the disease, as well as coping with painful treatments or the daily fear of dying.

Families of cancer patients and caregivers of those who are totally dependent may also develop depression due to mental exhaustion and the constant worry of losing a loved one. 

Misinformation about the disease, radical lifestyle changes and financial strain related to illness are strong risk factors that can also give rise to depression.

4. Hormonal imbalances

Hormonal imbalances, like decreased estrogen that occurs during pregnancy, post-partum and menopause, can also play a role in the development of depression. A lack of omega-3 can also decrease a person’s capacity to manage their emotions and mood. 

5. Medications

Prolonged use of medications like levodopa, alprazolam, simvastatin, aciclovir can decrease serotonin production, which can lead to depression. Serotonin is a hormone that is related to your sense of happiness and wellbeing. Nonetheless, not all people who take these medications will develop depression.
