Abnormal uterine bleeding (AUB) is any symptomatic variation from normal menstruation in terms of regularity, frequency, volume, or duration. It may be acute, chronic, or intermenstrual.
AUB affects up to 30% of women of reproductive age.
Causes include leiomyomata (fibroids), adenomyosis, endocervical and endometrial polyps, malignancy, endometrial hyperplasia, ovulatory or endometrial dysfunction, coagulopathy, and iatrogenic causes.
Initial evaluation includes a medical, surgical, and gynecological history, and pelvic examination. Further investigations may include blood tests and ultrasound.
