Menopause technically refers to the time after your periods have stopped for a full year and occurs, on average,
at age 51. Perimenopause -- the period leading up to menopause -- typically lasts about four years but can range from a few months to 10 years.
Estrogen and progesterone levels fluctuate throughout this process but as a woman gets closer to menopause, symptoms such as those above become more
likely. In addition, she may have insomnia, vaginal dryness, fatigue, and changes in sexual arousal and function.
