Abnormal (or dysfunctional) uterine bleeding is vaginal bleeding that is abnormally frequent, infrequent, heavy, or light. Every year, more than a million women complain of heavy or irregular periods. The terms are relative, but heavy bleeding is classified as a 50% increase in normal flow, or soaking through more than 10 tampons or sanitary pads in a day. Bleeding that lasts longer than a week is also considered to be heavy. Getting a short or light period every two to three weeks instead of one monthly period is considered to be irregular, as is spotting or missing periods altogether.Half of abnormal uterine bleeding cases occur during the childbearing years. Pregnancy is the most common cause of missed periods. The hormonal changes that occur during the years leading up to menopause (known as perimenopause) are another common cause of skipped periods and menstrual irregularities.If you have the Symptoms of Uterine Bleeding--Abnormal vaginal bleeding, we would say herbal medicine is a safe and effective form of treatment.
