What is depression?
Depression is more than a feeling of being sad or irritable for a few days. It's a serious mood disorder. As one of the most common mental disorders in the United States, depression can affect how you think, feel, and your everyday life. You may not know why you feel this way, but even basic daily activities such as sleeping, eating, or working may become difficult. Depression often needs long-term treatment but getting help at the earliest sign of a problem can help manage your symptoms.
What are the different types of depression?
The most common types of depression are major depression and persistent depressive disorder.
- Major depression symptoms include a depressed mood or a loss of interest. Symptoms affect your daily activities and last for at least two weeks.
- Persistent depressive disorder (also called dysthymia or dysthymic disorder) has less severe depressive symptoms, but they last longer, usually for at least two years.
Other types of depression can include:
- Seasonal affective disorder comes and goes with the seasons. It usually starts in late fall and early winter and goes away during the spring and summer.
- Bipolar disorder is sometimes called manic depression. This mood disorder can cause intense mood swings.
- Depression with symptoms of psychosis is a severe form of depression that also has delusions (false beliefs) or hallucinations (seeing, hearing, or feeling something that isn't there).
What causes depression?
There are a variety of things that may cause depression, including genetic, biological, environmental, and psychological factors. Depression can happen at any age and can affect anyone, but it's more common in women. This is often due to the physical and hormonal changes that women have during menstruation, pregnancy, the postpartum period, and menopause. Other mental disorders or chronic medical conditions such as diabetes, cancer, or heart disease may occur with depression. This may make the chronic condition or depression worse.
In some cases, there is no clear cause for depression.
Who is at risk of depression?
You may be at a higher risk of depression if you have a close relative who has it or another mental health disorder. Going through trauma or stressful life events may raise your risk even more.
What are the symptoms of depression?
Depression doesn't look the same on everyone. The type and number of symptoms of depression can vary and don't always appear like sadness. Depression may affect you differently based on your:
- Age. The symptoms of depression may be different in a child, who may appear more irritable than sad. Teens may act out or have excessive sleepiness. The symptoms for an older adult may not be as obvious as other age groups.
- Sex. Men often show symptoms and coping behaviors differently than women. Rather than sad, men may appear angry or irritable.
- Medical conditions. Some medicines and medical conditions may cause symptoms that look like depression. Chronic conditions may make depression worse.
Symptoms of depression are ongoing and affect your day-to-day life. They can include:
- Feeling sad or "empty"
- Losing interest in favorite activities
- Overeating, or not wanting to eat at all
- Sleeping too much, or not enough
- Feeling very tired
- Feeling hopeless, irritable, anxious, or guilty
- Having aches and pains, headaches, cramps, or digestive problems
- Having thoughts of death or suicide
- Changing moods or behaviors
- Increasing use of alcohol or drugs
- Isolating from family and friends
How is depression diagnosed?
If you think you have depression, talk to your health care provider or a mental health provider. To be diagnosed with depression, your provider may use many tools:
- A medical history will include asking about your symptoms and family history. To be diagnosed with depression, your symptoms must occur most of the day, nearly every day, for at least two weeks. One of the symptoms must be a depressed mood or a loss of interest in most activities.
- Medical tests may be done to rule out other medical conditions. Certain medicines and medical conditions (such as viruses or thyroid disorders) may cause symptoms like depression.
- A physical exam to make sure another issue isn't causing your symptoms.
- A mental health evaluation by your provider or a mental health provider.
What are the treatments for depression?
Depression may need long-term treatment. Most treatments include medicines and/or psychotherapy (talk therapy):
- Medicines such as antidepressants may help control your symptoms. You may need to try several medicines to find which works best for you. Medicine may take time to work and can have side effects. Don't stop taking your medicine without first talking with your provider. Contact your provider if you have any concerns about side effects from the medicine.
- Psychotherapy (talk therapy) under the care of a mental health provider can help you recognize and change troubling emotions, thoughts, and behaviors. This may be done one-on-one or in a group setting. It can give you and your family support, education, skills, and coping strategies.
- Light therapy has been shown to be effective for seasonal affective disorder (SAD).
- Other treatments options may be considered if treatment isn't working or if depression is severe. These may include:
- Electroconvulsive therapy (ECT) is a brain stimulation procedure that uses a mild electric current when you are under general anesthesia. ECT is most often used for severe depression that is not getting better with other treatments.
- Repetitive transcranial magnetic stimulation (rTMS) is a brain stimulation procedure that uses magnetic waves to relieve depression. It's not as powerful as ECT, but with rTMS, you don't need anesthesia. It also has a low risk of negative effects on your memory and thinking.
Can depression be prevented?
Most cases of depression can't be prevented, but healthy lifestyle changes can have long-term benefits for your mental health. These can include:
- Getting regular exercise
- Having a consistent sleep schedule
- Controlling stress
If you, or someone you love is depressed, see your provider or a mental health provider. It's important to get treatment at the earliest sign of a problem.
If you or someone you know has thoughts of hurting themselves or attempting suicide, get help right away. If it is an emergency, dial 911.

What is
postpartum depression?
Having a baby can be exciting, but it can also be stressful and bring many strong emotions. During the postpartum period, which is the time after you give birth, you may have mood swings, crying spells, or feel anxious. These feelings are common and are often called the postpartum "baby blues". The baby blues usually go away within a few days to a week.
If your symptoms are more severe and last longer than two weeks, you may have postpartum depression.
Postpartum depression is a common but serious mood disorder that can begin anytime within the first year after childbirth. Without treatment, symptoms may make it hard to care for your baby or manage daily tasks.
What causes
postpartum depression?
The exact cause is unknown, but postpartum depression likely results from a combination of factors, including:
- Sudden changes in hormone levels after pregnancy
- Physical changes, such as dropping thyroid hormone levels
- Lifestyle factors, such as fatigue, lack of sleep, limited support, or recent stressful events
Who is at risk for
postpartum depression?
Anyone can develop postpartum depression after childbirth. You might be at higher risk if you:
- Have a history of depression, bipolar disorder, or a family health history of these conditions
- Had a multiple birth (twins, triplets, or more)
- Gave birth while in your teens
- Had health problems during pregnancy
- Had preterm labor or other complications during childbirth
- Have a baby with special needs
- Have ever experienced domestic violence
- Are dealing with financial stress
- Had an unplanned pregnancy
What are the symptoms of
postpartum depression?
Postpartum depression symptoms are more intense and last longer than the baby blues.
Symptoms may include:

- Eating too much or too little
- Sleeping too much or too little
- Crying more than usual or for no clear reason
- Feeling unusually angry
- Pulling away from family and friends

If these symptoms begin during pregnancy and continue after childbirth, it's called perinatal depression. Without treatment, it can affect bonding with your baby and may contribute to feeding or sleeping problems.
Very rarely, a new mother may develop postpartum psychosis, a medical emergency. Symptoms may include confusion, hallucinations (seeing or hearing things that aren't real), or dangerous behaviors. Call 911 or go to the nearest emergency room right away if this happens.
