A woman will have about 450 periods in her lifetime, and before each of these periods, three out of four women experience PMS or premenstrual syndrome, symptoms that are often inconvenient and disruptive. Even the Ancient Greeks talked about the physical and emotional changes associated with PMS, but it was not until relatively recently (1931) that modern medicine officially recognized the condition; the term “Premenstrual syndrome” wasn’t coined until 1953.
Premenstrual syndrome, or PMS, is a combination of physical, emotional, and psychological symptoms and mood disturbances that begin one to two weeks before a woman's period begins. These symptoms tend to recede around the start of the menstrual flow, or a few days later. For most women, PMS symptoms are a nuisance they can treat at home or even ignore if they are mild enough. For some, however, the symptoms can be severe enough to be debilitating and require time off of work.
