Re: Menopause...do the FSH numbers change first?
A number of things can cause your FSH numbers to jump all over the place. Diet, exercise, the amount of fish oils you're getting, whether you're annovulatory, etc etc etc all those things can affect FSH. Often, women who are trying to get pregnant but have higb FSH levels will do massive changes like diet, exercise, accupuncture, herbs etc to lower their FSH levels. It works in some women.
Not sure how old you are but if you're entering the end of your fertile period and are facing a diminished egg supply, then just the failure that month to ovulate any kind of egg at all can cause your FSH to jump.
FSH numbers are not a stable thing that gradually go up as we get older. We don't have an FSH in our 20's of 3.5, that slowly graduates up to an FSH of 6.5 in our 30's and then jumps to 10'5 in our 40's. It's more complicated than that. It's all tied into ovarian reserve (we're all born with a set number of eggs) and it's tied into ovulation of those eggs. Over the course of a year, FSH numbers can jump up and down from month to month. The most they are is an indicator of what is happening within our bodies but not a true blue map.
