Often, it is observed that women reach menopause around the same age as their mothers. So genes tend to play a role. An active lifestyle, ideal weight and a healthy BMI (body mass index) tend to have a later menopause.Smokers may reach menopause about 2 years earlier than non-smokers. Multiple factors affect the menopause transition in a woman's body: genes, lifestyle, mental and emotional stress, nutrition etc Each of us, therefore, is different and unique.
