The average age a woman experiences menopause is 51 years old. The process can begin as early as her 30s or as late as her 60s, according to MedicineNet.
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.
