What Are the Main Causes of Depression?

Causes of Depression:

Depression is a very complex disease. It occurs for various causes. Some people experience depression during a serious medical illness. Others may have depression with life changes such as a move or the death of a loved one. Still others have a family history of depression. Those who do may experience depression and feel overwhelmed with sadness and loneliness for no known reason.

There are a number of causes that may increase the chance of depression, including the following:

Family history – Depression can run in families and some people will be at an increased genetic risk. Life circumstances and other personal factors are likely to have an important influence.

Personality – Some people may be more at risk of depression because of their personality, particularly if they have a tendency to worry a lot, have low self-esteem, are perfectionists, are sensitive to personal criticism, or are self-critical and negative.

Abuse - Past physical, sexual, or emotional abuse can cause depression later in life.

Certain medications - For example, some drugs used to treat high blood pressure, such as beta-blockers or reserpine, can increase the risk of depression.

Conflict - Depression may result from personal conflicts or disputes with family members or friends.

Death or a loss - Sadness or grief from the death or loss of a loved one, though natural, can also increase the risk of depression.

Major events - Even good events such as starting a new job, graduating, or getting married can lead to depression. So can moving, losing a job or income, getting divorced, or retiring.

Serious medical illness – Having a medical illness can trigger depression in two ways. Serious illnesses can bring about depression directly, or can contribute to depression through associated stress and worry, especially if it involves long-term management of the illness and/or chronic pain.

Drug and alcohol use – Drug and alcohol use can both lead to and result from depression. Many people with depression also have drug and alcohol problems.

Substance abuse - Nearly 30% of people with substance abuse problems also have major or clinical depression.

Giving birth - Some women are particularly vulnerable to depression after pregnancy. The hormonal and physical changes, as well as added responsibility of a new life, can lead to postnatal depression.

Early childhood trauma - Traumatic events during childhood, such as abuse or loss of a parent, may cause permanent changes in the brain that make you more susceptible to depression.
