How common is abnormal uterine bleeding?

Not everyone who experiences abnormal uterine bleeding reports their symptoms. As a result, 10% to 35% of women worldwide may have abnormal uterine bleeding. But the numbers may be higher. It’s most common during menarche (when menstruation begins) and perimenopause (the years leading up to menopause).

Hormone imbalances are often to blame for abnormal uterine bleeding. They’re most common among people whose periods are just beginning or near ending.
