Depression may be described as feeling sad, blue, unhappy, miserable, or down in the dumps. Most of us feel this way at one time or another for short periods. But true clinical depression is a mood disorder in which feelings of sadness, loss, anger, or frustration interfere with everyday life for an extended time.

Depression is generally ranked in terms of severity -- mild, moderate, or severe. The degree of your depression, which your doctor can determine, influences how you are treated. Symptoms of depression include:
Low self esteem is common with depression. So are sudden bursts of anger and lack of pleasure from activities that normally make you happy, including sex.
Depressed children may not have the classic symptoms of adult depression. Watch especially for changes in school performance, sleep, and behavior. If you wonder whether your child might be depressed, it's worth bringing to a doctor's attention.
The main types of depression include:
Other common forms of depression include:
Depression may also occur with mania (known as manic-depression or bipolar disorder). In this condition, moods cycle between mania and depression.
Depression is more common in women than men and is especially common during the teen years. Men seem to seek help for feelings of depression less often than women. Therefore, women may only have more documented cases of depression.
Depression often runs in families. This may be from heredity, learned behavior, or both. Even with a genetic predisposition, it is usually a stressful or unhappy life event that triggers the onset of a depressive episode.
Depression may be brought on by:
If you are depressed for 2 weeks or longer, you should contact your doctor, who can offer treatment options. Regardless of whether you have mild or major depression, the following self-care steps can help:
It may be helpful to add omega-3 fatty acids to your diet, which you can get from cold-water fish like tuna, salmon, or mackerel. Taking folate (vitamin B9) may be helpful. Appropriate amounts of folate (400 to 800 micrograms) are found in many multivitamins.
If your depression occurs in the fall or winter months, try light therapy using a special lamp that mimics the sun.
Many people try a popular over-the-counter herb called St. John's Wort. Some studies do suggest that this herbal remedy may be helpful for mild depression, but not moderate or severe. Be aware that St. John's Wort has potential drug interactions and should NOT be taken with prescription antidepressants, birth control pills, protease inhibitors for HIV, theophylline, warfarin, digoxin, reserpine, cyclosporine, or loperamide. Talk to your doctor if you are thinking about trying this herb for mild depression.
If you have moderate to severe depression, the most effective treatment plan will likely be a combination of counseling and medication.
Call your health care provider if
Call 911, a suicide hotline, or get safely to a nearby emergency room if you have thoughts of suicide , a suicidal plan, or thoughts of harming yourself or others.
Call your doctor right away if:
A complete history, a psychiatric interview and a physical examination will be performed to try to classify your depression as mild, moderate, or severe and to see if there is an underlying, treatable cause (such as alcohol abuse or an underactive thyroid). Hospitalization is usually recommended if suicide seems possible.
Expect some exploration of the issues and events associated with your feelings of depression. Your doctor will ask you about:
Treatment will vary according to the cause and severity of your depressive symptoms, as well as your personal preference. The most effective therapy for moderate or severe depression is a combination of antidepressant medication and psychotherapy.
For mild depression, counseling and self-care measures without medication may be enough.
If you are taking medications for other purposes that could cause depression as a side effect, these may need to be changed. DO NOT change or stop any of your medications without consulting your doctor.
For people who are so severely depressed as to be unable to function, or who are suicidal and cannot be safely cared for in the community, psychiatric hospitalization may be necessary.
Healthy lifestyle habits can help prevent depression, or lessen the chances of it happening again. These habits include eating properly, sleeping adequately, exercising regularly, learning to relax, and not drinking alcohol or using drugs.
Counseling may help you through times of grief, stress, or low mood. Family therapy may be particularly important for teens who feel blue.
For elderly or others who feel socially isolated or lonely, try volunteering or getting involved in group activities.
