What Increases Your Risk

Factors that increase your risk of developing dysfunctional uterine bleeding (DUB) include:

• Your age. Dysfunctional uterine bleeding is more common in teens, at the beginning of the reproductive years, and in perimenopausal women at the end of their reproductive years.
• Your weight. Overweight women more commonly develop dysfunctional uterine bleeding.¹

Some women have dysfunctional uterine bleeding even though they have no risk factors.
