For each woman perimenapause is different... it can be a few years to even 5-10 years. If you are able to speak with your health care provider, then they can give you information on what to expect pre-menapause, menapause, and post-menapause. Not all women experience the same changes that occur as our bodies goes through it's seasons.
Hi,
The period of pre-menopause which leads up to menopause can be variable from person to person. It depends on the hormonal status, body weight and family history.
Hope this helps.
