The gradual transition between the reproductive years and menopause (the cessation of menstrual periods) is called perimenopause (literally meaning “around menopause”). It is generally a transition that is many years long and can be associated with shorter menstrual intervals, irregular menses, night sweats, and other symptoms. In some women, these symptoms are troublesome enough to need medical intervention.
Most women experience menopause between ages 40 and 58. The average age is 51.
Physical changes begin years before the final menstrual period. This transition phase is called perimenopause and may last for 4 to 8 years. It begins with changes in the length of time between periods and ends 1 year after the final menstrual period.
