Depression is not merely a state of mind--it is not an illness someone can snap out of when they choose. Its causes are complex, and often it is a combination of causes responsible for this disorder, according to Depression.com. While all causes have yet to be identified, doctors have enough information to help those suffering from this condition.
Hormonal Factors
Gender is a contributing factor for depression, the Mayo Clinic explains, and women face a greater risk factor for developing depression due to hormones. The site states that hormonal changes women experience may cause depression.
Dr. Arthur Schoenstadt of eMedTV.com agrees, explaining that hormonal changes taking place during menstrual cycles, pregnancy, miscarriage, perimenopause and menopause can contribute to this disorder.
Pessimism
Pessimism can stem from low self-esteem or may be a learned behavior. Psychology Information Online explains that a child who is raised in a home where negativity is normal and encouragement is rare is more likely to develop depression.
Psychology Information Online adds that those with low self-esteem tend to view themselves and the world around them in a negative light. This way of thinking increases their chances of being overwhelmed by stress.
Chemical Messengers
Chemical messengers in the brain, also known as neurotransmitters, are responsible for regulating mood and are thought to play a significant role in depression, according to the Mayo Clinic. The most common chemical messengers are serotonin, norepinephrine and dopamine--when these are out of balance, they can have an adverse affect on a person's mood, thus resulting in depression.
Environmental Stress
Stress presents itself in a variety of forms--the breakup of a relationship, financial difficulties and the death of family members or friends. As Depression.com explains, moments of happiness can also be sources of stress, resulting in depression. Examples of these include weddings, a new job and having a baby. Everyone's source of stress varies, as does their ability to cope with this stress.
Medical Reasons
Medical conditions can either be the cause or effect of depression. Serious health conditions such as HIV/AIDS, cancer and heart disease cause depression due to the immense stress and physical weakness they cause. Depression can worsen these conditions, as it causes the immune system to weaken. In certain instances, the medications doctors prescribe as a form of treatment may cause depression as well.
