Menstrual periods vary from woman to woman. Most women have a normal period approximately every 28 days, and each period typically lasts from four to seven days. The amount of blood lost during a menstrual period ranges from 20 to 80 milliliters (mL). Blood loss of more than 80 mL may be considered a heavy period. A possible indication of heavy periods is soaking through a feminine hygiene product (pad or tampon) every hour for as long as three hours straight. Nearly one-third of women experience menorrhagia during adolescence or adulthood.Heavy periods may occur for various reasons, including hypothyroidism, abnormal blood clotting, a disorder of the uterus, anovulation, or hormonal imbalances. For instance, endometrial hyperplasia occurs when there is excessive growth of the cells that line the uterus. This condition may result from disruption of the two hormones (estrogen and progesterone) that control menstrual periods.If you have the Symptoms of Hypothyroidism--Heavy period, we would say herbal medicine is a safe and effective form of treatment.
