Study, 2026

What are premenstrual syndrome and premenstrual dysphoric disorder?

Between 5% and 8% of women have moderate-to-severe symptoms that cause significant problems with work, relationships, and daily life. These are called PMS or PMDD. PMDD is the most severe form.

What they did

This describes what we know about premenstrual disorders, their symptoms, and how they are diagnosed.

What they found

Most women experience mild premenstrual discomfort. Symptoms start 1 to 2 weeks before menstruation. Between 5% and 8% of women develop moderate-to-severe symptoms with significant disruption to daily life, work, and relationships. Women with PMS or PMDD have greater loss in quality of life and work productivity than women with mild or no symptoms.

What it means for you

If you have moderate-to-severe premenstrual symptoms affecting your life, you are in a smaller group of women, but your experience is real and treatable. The main difference between PMS and PMDD is how severe the symptoms are. PMDD is recognized as a psychiatric diagnosis because of its severity.
