What Affects Abnormal Uterine Bleeding?

Abnormal uterine bleeding can occur when a women ovulates irregularly, which is common in the teenage and perimenopausal age group. However, abnormal uterine bleeding can occur at any time during a woman’s reproductive life.

On average, a normal menstrual flow typically occurs every 21-28 days. With normal menstruation, women lose about 2 to 2½ ounces of blood (in addition to fluid) during each period. Simple changes that include stress level, diet changes, exercise routine, recent weight gain or loss, or trying a new birth control method can all affect a woman’s menstrual flow.
