What is premenstrual dysphoric disorder (PMDD)?

Premenstrual dysphoric disorder (PMDD) is a much more severe form of premenstrual syndrome (PMS). It may affect women of childbearing age. It’s a severe and chronic health condition that needs attention and treatment. Lifestyle changes and sometimes medicines can help manage symptoms.

What causes PMDD?

The exact cause of PMDD is not known. It may be an abnormal reaction to normal hormone changes that happen with each menstrual cycle. The hormone changes can cause a serotonin deficiency. Serotonin is a substance found naturally in the brain and intestines that narrows blood vessels and can affect mood and cause physical symptoms.

Who is at risk for PMDD?

Any woman can develop PMDD, but the following may be at an increased risk:

• Women with a family history of PMS or PMDD  

• Women with a personal or family history of depression, postpartum depression, or other mood disorders

Other possible risk factors include lower education and cigarette smoking.

Talk with your healthcare provider for more information.

What are the symptoms of PMDD?

Symptoms of PMDD start during the week before menstruation and end within a few days after your period starts. These symptoms disrupt daily living tasks. Symptoms of PMDD are so severe that women have trouble functioning at home, at work, and in relationships during this time. This is markedly different than other times during the month.

The symptoms of PMDD may look like other health conditions, such as a thyroid condition, depression, or an anxiety disorder. Always see a healthcare provider for a diagnosis.

How is PMDD diagnosed?

Aside from a health history and physical and pelvic exam, there are very few diagnostic tests. Because you may have mental health symptoms, your healthcare provider may want you to be evaluated for mental health concerns. Your provider may also ask that you keep a journal or diary of your symptoms for several months. In general, to diagnose PMDD the following symptoms must be present:

• Over the course of a year, during most menstrual cycles, you must have 5 or more of these symptoms:

  • Depressed mood

  • Anger or irritability

  • Trouble concentrating

  • Lack of interest in activities once enjoyed

  • Insomnia or the need for more sleep

  • Feeling overwhelmed or out of control

  • Other physical symptoms, the most common being belly bloating, breast tenderness, and headache

• Symptoms that disturb your ability to function in social, work, or other situations

• Symptoms that are not related to or made worse by another health condition

How is PMDD treated?

PMDD is a serious, long-term (chronic) condition that does need treatment. Several of the following treatment approaches may help ease or decrease the severity of PMDD symptoms:

• Changes in diet to increase protein and carbohydrates and decrease sugar, salt, caffeine, and alcohol

• Regular exercise

• Stress management

• Vitamin supplements such as vitamin B-6, calcium, and magnesium

• Anti-inflammatory medicines

• Selective serotonin reuptake inhibitors (SSRIs)

For some women, the severity of symptoms increases over time and lasts until menopause. For this reason, a woman may need treatment for an extended time. Medicine dosage may change throughout the course of treatment.
