What this symptom means

Sadness is a normal human response to loss and difficulty. Depression is different: it lasts most of the day, nearly every day, for at least two weeks, and typically includes a loss of interest in things you previously enjoyed. It is a medical condition, not a personal failing, and it responds well to treatment.

Common causes

Major depressive disorder
Persistent depressive disorder
Bipolar disorder
Thyroid disorders and vitamin deficiencies
Grief and major life change
Chronic illness, pain, or medication side effects

Which doctor treats a depressed mood?

Persistent low mood is treated by a psychiatrist or by a psychologist or licensed therapist. A primary care physician is a practical first step, since they can screen for physical causes such as thyroid disease or anemia and begin treatment or refer you onward.

Call 911 or go to the nearest emergency room if you experience any of the following.

Thoughts of suicide or self-harm
A plan or intent to end your life
