Premenstrual Syndrome (PMS)

Premenstrual syndrome (PMS) is both physical and emotional symptoms such as bloating, tender breasts, food cravings, fatigue, irritability, and mood swings. These symptoms usually start in the two-week period after ovulation and before menstruation, due to estrogen and progesterone levels falling. Symptoms often go away once the period starts. Severe PMS symptoms may be a sign of premenstrual dysphoric disorder (PMDD). During perimenopause, both PMS and PMDD often get worse. Once a woman is postmenopausal, symptoms of PMS resolve.
