Menorrhagia is a medical term used to describe heavy or prolonged menstrual bleeding. Women experiencing menorrhagia may have periods that last longer than seven days or require changing sanitary products every hour. This condition can lead to anemia and fatigue due to significant blood loss. Several factors can contribute to menorrhagia, including hormonal imbalances, uterine fibroids, or certain medical conditions like thyroid disorders. Treatment options vary and may include medications, lifestyle changes, or surgical procedures, depending on the underlying cause and severity of the symptoms.
