Abnormal uterine bleeding in reproductive-aged women is a manifestation of a number of disorders or pathologic entities. In the clinical, women of reproductive age with heavy bleeding should be given immediate intervention to prevent further blood loss.
In most cases, it is associated with anovulatory or oligoovulatory cycles (irregular ovulation), leading to a shoot in the estrogen levels, which are unopposed due to absence of progesterone. When a woman is anovulatory, she can't get pregnant because there is no egg to be fertilized. Women who are anovulatory have irregular, few or no periods.
