Abnоrmаl uterine bleeding (AUB) describes аny symptоmаtic bleeding that deviates frоm a patient's normal menstrual patterns in terms of frequency, regularity, duration, or volume. Normal menstruation is defined by a frequency between 24 and 38 days with no more than 7 to 9 days difference between cycle lengths and a duration of up to 8 days for a single menstrual period. Normal menstrual volume is defined clinically as a volume that does not cause physical, social, or emotional impact on a patient's daily life. The International Federation of Gynecology and Obstetrics (FIGO) developed the PALM-COEIN acronym to further classify and identify AUB etiologies. This acronym stands for polyp, adenomyosis, leiomyoma, malignancy and hyperplasia, coagulopathy, ovulatory dysfunction, endometrial dysfunction, iatrogenic, and not otherwise classified. Pregnancy should be excluded in all reproductive-aged patients prior to initiating a workup for AUB. Further evaluation consists of a thorough gynecologic and obstetric history, medical history, and current medication usage. The clinician should focus on the frequency, regularity, duration, and volume of the bleeding and the deviations of this pattern from the reported menstrual history. Physical evaluation should aim to rule out obvious sources of bleeding from the vulva, vagina, perineal area, cervix, and anus. Initial laboratory tests include human chorionic gonadotropin (hCG) and complete blood count. Pelvic ultrasonography is the first-line imaging of choice for diagnosing and further evaluating the etiology of AUB in most healthy premenopausal patients and is best performed transvaginally. Endometrial biopsy should be alternatively performed for patients with risk factors for endometrial cancer (e.g., unopposed estrogen therapy, tamoxifen use, menopause after age 55, obesity, polycystic ovary syndrome, or diabetes mellitus). Patients with irregular bleeding (i.e., cycle length variance> 7 to 9 days) are most likely to have underlying ovulatory dysfunction (AUB-O). This pathology occurs at the extremes of reproductive age due to the non-cyclical production of sex steroids leading to unopposed estrogen-mediated proliferation of the endometrium. In post-menarchal girls, hypothalamic-pituitary-ovarian axis immaturity commonly results in heavy, irregular menstrual cycles that regulate over the years. AUB is managed by identifying and properly treating the underlying etiology. Initial goals include decreasing bleeding, treating anemia if present, and restoring quality of life. Pharmacologic approaches are common first-line treatments and include hormonal treatment, tranexamic acid, and nonsteroidal anti-inflammatory drugs. Secondary surgical approaches include myomectomy in those desiring to preserve fertility, with endometrial ablation, uterine artery embolization, and hysterectomy being options in women who no longer desire future fertility.
