Menopause is the term that describes the absence of a menstrual cycle for a period of at least 12 months. Menstrual cycles start varying in length during the transitional phase, sometimes referred to as "perimenopause," as MedicineNet explains. "Postmenopause" is the term that describes the time after the last menstrual period.
Some menopause symptoms are irregular or abnormal bleeding, mood swings and hot flashes. Doctors customize menopause treatment for each patient.Learn more about Menstruation
