Premenstrual Syndrome. A combination of distressing physical, psychologic, or behavioral changes that occur during the luteal phase of the menstrual cycle. Symptoms of PMS are diverse (such as pain, water-retention, anxiety, cravings, and depression) and they diminish markedly 2 or 3 days after the initiation of menses.
Around 85 percent of women report some emotional or physical changes around the time their period occurs. If these physical and emotional symptoms are severe, it might be a sign of premenstrual syndrome (PMS). PMS usually begins one or two weeks before menstruation and is brought on by rising and falling hormonal levels just before the period begins.
