Intense menstrual flow may be a consequence of some hormonal out-of-control, although the uterine bleeding varies greatly from woman to woman, both in volume and duration.
The menstrual flow may be intense, mild, frequent, or irregular. The cause of the differences may be physical or hormonal. When a woman is of reproductive age, these changes are more frequent and generally do not represent disease although they cause some discomfort. In some situations anemia may develop.
In cases where no cause for abnormally intense menstrual flow is detected, it is called dysfunctional uterine bleeding and is very common at the extremes of a woman's life as early in adolescence and close to the menopause period.
