Anovulatory Bleeding

Excerpt

Abnormal uterine bleeding associated with ovulatory dysfunction (AUB-O) or anovulatory bleeding, is non-cyclic uterine bleeding characterized by irregular, prolonged, and often heavy menstruation. It represents one of the identified causes of abnormal uterine bleeding (AUB), a frequently encountered chief complaint in the primary care setting affecting up to one-third of women of child-bearing age. Though commonly observed during menarche and perimenopause, it can present at any stage of reproductive life. AUB-O is a diagnosis of exclusion; other structural and physiologic etiologies of AUB should be ruled out by history, physical exam, or with laboratory analysis and imaging as appropriate.
