Abnormal Vaginal Bleeding Definition
Dysfunctional uterine bleeding (DUB) is abnormal vaginal bleeding that occurs during a menstrual cycle that produced no egg (ovulation did not take place).
Abnormal Vaginal Bleeding Causes, Incidence, and Risk Factors
Anovulatory or dysfunctional uterine bleeding
is a diagnosis of exclusion. This means that it is determined only AFTER other
causes of abnormal uterine bleeding -- such as systemic diseases, medications,
early pregnancy disorders, eating disorders, gynecological infections,
structural anomalies, or tumors -- have been ruled out.
Abnormal Vaginal Bleeding Symptoms
Abnormal Vaginal Bleeding Signs and Tests

Abnormal Vaginal Bleeding Treatment
Young women within several years of menarche (the first menstrual period) are not treated unless symptoms are exceptionally severe, such as heavy blood loss causing anemia.
In women of childbearing age, treatment is aimed at achieving regular menstrual cycles with normal patterns. Oral contraceptives or progestogen therapy are frequently used for this purpose. If anemia is present, iron supplementation may be recommended. If pregnancy is desired, ovulation induction may be attempted with medication.
Women whose symptoms are severe and resistant to medical therapy may choose surgical treatments including endometrial ablation (a procedure that burns or removes the lining of the uterus) or hysterectomy.
In older women who may be approaching menopause, treatment may be elected to offset symptoms. Women may choose from treatments such as hormone supplementation or surgery.
Abnormal Vaginal Bleeding Expectations (prognosis)
Hormonal regulation is usually successful in alleviating symptoms. Induced ovulation, in women desiring pregnancy, is successful in approximately 80% of cases.
Abnormal Vaginal Bleeding Complications
Calling your health care provider
