Menopause is a natural event that normally occurs between the ages of 45 and 55.
Once menopause is complete (called post menopause) and you have not had a period for 1 year, you can no longer become pregnant.
The symptoms of menopause are caused by changes in estrogen and progesterone levels. As the ovaries become less functional, they produce less of these hormones and the body responds accordingly. The specific symptoms you experience and how significant (mild, moderate, or severe) varies from woman to woman.
