The normal age range for menopause is between 45 and 55 years, advise MedicineNet.com. Some women enter into premature menopause in their 30s, while other women reach menopause in their 60s.

Menopause marks a one-year absence of menstrual periods, and the average age of American women at menopause is 51. The phase leading up to menopause is known as perimenopause, which is a transition period that results from changing levels of estrogen and progesterone hormones in the ovaries. Although perimenopause is a natural part of the female aging process, the National Institute on Aging reports that some women may experience unwanted side effects during this life stage. These side effects may include hot flashes, night sweats, interrupted sleep or mood changes.
