High Quality Content by WIKIPEDIA articles! Premenstrual syndrome (PMS) (also called PMT or premenstrual tension) is a collection of physical, psychological, and emotional symptoms related to a woman's menstrual cycle. While most women of child-bearing age (up to 85%) report having experienced physical symptoms related to normal ovulatory function, such as bloating or breast tenderness, medical definitions of PMS are limited to a consistent pattern of emotional and physical symptoms occurring only during the luteal phase of the menstrual cycle that are of "sufficient severity to interfere with some aspects of life".
