What is premenstrual syndrome?

Premenstrual syndrome causes numerous symptoms during the week before menstruation, including depression, moodiness, lower back pain, and many other possible symptoms.

Premenstrual Syndrome, or PMS, affects about 80 percent of women during their reproductive years. In fact, one out of every 10 women has severe PMS that disrupts work or school attendance.

Unfortunately, PMS complaints have often been viewed throughout history as a mere psychological over-reaction. But the possible 150 symptoms that manifest for many women in the week before menstruation are by no means imagined. In addition to the characteristic moodiness and bloating, some women experience diarrhea, lower back pain, headaches, insomnia, and many other symptoms.
