Menopause is a condition experienced by women from the age 40 to 55 where their menstrual cycles stop for at least 12 months. In certain cases, if a menstrual cycle stops before the age of 45 then it can be classified as premature menopause. 

Almost 5 to 10 per cent of women in the world are prone to experience premature menopause. This can be caused due to various reasons such as genetics, certain lifestyle factors, and especially due to the correlation between cigarette smoking.
