Why do some women suffer from Premenstrual Syndrome? Almost all women have some discomfort the days prior to their period, usually tolerable, and considered a normal part of the hormonal cycle at a fertile age. However, in some cases, these changes are important and some symptoms may be incapacitating.

Usually, any process that changes the cervix may cause Premenstrual Syndrome. In many cases, patients cannot remember any event related to the beginning of the symptoms, and some relate it back to their first period….. But, in many other cases, there is background related to the development of the disease. Childbirth is the most frequent event related to PMS. In fact, childbirth involves intense trauma to the cervix, since it dilates to reach the diameter of the baby’s skull. Of course, most mothers are able to heal and correct it after delivery, but in some cases, the damage done to the cervix results in PMS.

Uterine infections or pelvic inflammatory disease are also events related to PMS, since they affect the reproductive system. Chronic vaginal yeast infections are also associated to it, even though in some cases of chronic candidiasis and PMS, it is difficult to determine which is the cause and which is the consequence.
