Average Age of Menopause
The average age of menopause is 51. However, menopause can happen anytime, from your 30s to your mid-50s or later.
During menopause, a woman's body begins to make less of the hormones estrogen and progesterone -- this leads to the common symptoms of menopause. A woman is said to have reached menopause when she has not had a period for 12 months in a row and there are no other causes for this change.
Interestingly, 100 years ago, the average age of menopause was 45. However, the average life expectancy for women was 49. Today, the average age has increased to 51, and the average female life expectancy is close to 80.
