Causes & Risk Factors

What causes PMDD?

The exact cause of PMDD is not known. Changes in hormones related to your period may cause PMDD. Stressful life events and a family history of PMS or PMDD may increase your chances of getting PMDD. Major depression is common in women who have PMDD. However, not all women who have PMDD have major depression.

Diagnosis & Tests

How does my doctor find out if I have PMDD?

Your doctor will check your symptoms and the way they relate to your menstrual cycle. You might fill out a symptom chart for several weeks. There is no test that can diagnose PMDD.

Treatment

How is PMDD treated?

Your doctor will ask you about your symptoms are and will discuss different treatments with you. For mild to moderate symptoms, your doctor may suggest changes in your diet and lifestyle. You might talk to a counselor about your PMDD symptoms and life stresses. Medicines may help with severe symptoms.

What medicines are helpful?

Certain medicines used to treat depression also treat PMDD. Selective serotonin reuptake inhibitors (SSRIs) help by increasing the effect of a brain chemical called serotonin.

Does that mean I have depression?

No. These medicines work for both conditions.

How often do I have to take these medicines?

Some of these medicines you take for 10 to 14 days before each period.

Your doctor knows about other treatments. After talking with you, your doctor might have you try something else.
