What is it?
Premenstrual syndrome (PMS) is the physical and psychological symptoms that happen each menstrual cycle. They happen during the luteal phase which is the time after a woman has ovulated . The symptoms settle when their period starts. As many as two in five women will have these symptoms. Women who have PMS are potentially at a higher chance of having a mood disorder during menopause.
Premenstrual dysphoric disorder (PMDD) is a more severe form of PMS. It includes symptoms of anger, irritability, and internal tension during the luteal phase. This can cause significant distress for women and affect daily functioning. Less than eight percent of women will have PMDD.
