Major depressive disorder, commonly referred to as "depression," can severely disrupt your life, affecting your appetite, sleep, work, and relationships.

The symptoms that help a doctor identify depression include:

1.constant feelings of sadness, irritability, or tension

2.decreased interest or pleasure in usual activities or hobbies

3.loss of energy, feeling tired despite lack of activity

4.a change in appetite, with significant weight loss or weight gain

5.a change in sleeping patterns, such as difficulty sleeping, early morning awakening, or sleeping too much

6.restlessness or feeling slowed down

7.decreased ability to make decisions or concentrate

8.feelings of worthlessness, hopelessness, or guilt

9.thoughts of suicide or death


If you are experiencing any or several of these symptoms, you should talk to your doctor about whether you are suffering from depression.

If you are in an immediate serious crisis please contact your doctor or go to your local hospital or emergency room.

Dysthymia is another mood disorder. People who have it may feel mildly depressed on most days over a period of at least two years. They have many symptoms resembling major depression, but with less severity.

Symptoms of depression may surface with other mood disorders. They include seasonal major depression (also known as seasonal affective disorder), postpartum depression, and bipolar disorder.

Seasonal Affective Disorder has symptoms that are seen with any major depressive episode. It is the recurrence of the symptoms during certain seasons that is the hallmark of this type of depression.

Postpartum Depression is a type of depression that can occur in women who have recently given birth. It typically occurs in the first few months after delivery, but can happen within the first year after giving birth. The symptoms are those seen with any major depressive episode. Often, postpartum depression interferes with the mother's ability to bond with her newborn. It is very important to seek help if you are experiencing postpartum depression. Postpartum depression is different from the "Baby Blues", which tend to occur the first few days after delivery and resolve spontaneously.

Bipolar disorder, another mood disorder, is different than major depressive disorder and has different treatments.
