At what age does perimenopause typically start and how long does it last?
Dr. Susan Hutchinson discusses the typical age of onset of perimenopause, and the markers that define it in blood tests.
“The typical starting age would be about 47 years old. Some women it starts earlier. It's about a four-year period, and again this is an average. So around the age of 51, 52 it usually becomes what's called menopause. Now the definition of menopause is, no spontaneous bleeding for one full year, or there's a set of blood tests women can have and typically it would be an FSH and an estradiol. FSH stands for follicle stimulating hormone, it comes from the pituitary. And estradiol comes from the ovary. So, if a woman is now completely menopausal, think about her ovaries as going to sleep, then you would expect the estradiol, the estrogen level to be quite low and the FSH to be high. Because the pituitary is now sensing there is not enough estrogen. So to give an example, let's say I have a woman who hasn't had a period in three or four months, and she's wondering, ‘Am I menopausal, Dr. Hutchinson?' Well, she had a period three or four months ago, so I can't go by the absence for one full year. So that's when I might order the FSH and the estradiol.”
