The average age a girl starts her periods is 12 and the average age a woman completes the process of menopause is 52, so you would probably add about 40 years to your age. You know you are done with menopause when you have not had a period in one year.

34 menopause Symptoms

Menopausal symptoms affect about 70% of women approaching menopause. Typical menopause symptoms, such as hot flashes or night sweats, are caused by changing hormonal levels in the female reproductive system. Almost all women notice early symptoms while still having periods. This stage of gradually falling and fluctuating hormone levels is called perimenopause, which often begins in the early 40s.

The symptoms of menopause usually last for the whole menopause transition (until the mid 50s), but some women may experience them for the rest of their lives. The most common symptoms are: Hot Flashes, Night Sweats, Irregular Periods, Loss of Libido, and Vaginal Dryness.
However, there are a variety of treatments that can be considered to deal with these symptoms.
