Dysfunctional uterine bleeding.

DUB is a common adolescent problem usually related to HPO axis immaturity and anovulation. Modern hormonal and other medical therapies enable physicians to treat DUB effectively, regardless of the cause. The evaluation provides the physician with an opportunity to offer confidential education, reassurance, treatment, and appropriate intervention in cases in which a systemic or coagulation disorder may be the underlying pathophysiology involved.
