Basal Rates and Hormones

Women's Health Hormones

Sooooo…in researching progesterone, estrogen and menstrual cycle/blood sugar medical guidance…where are these “many women” who “report that their blood sugar increases 3 to 5 days before their period”? Lots of websites cite this generic “fact”, but I do not see a source anywhere. Maybe I am missing something?

Also, why are so many of these articles claiming that Progesterone and Estrogen are at their highest nearly immediately before your period? They’re not. Any hormone chart of menstrual cycles shows that they typically peak between Week 3 and Week 4, and decline for days leading into menstruation. Making lots of allowances for individual experiences being varied, I just can’t wrap my head around why the medical community claims that hormones CAN impact your blood sugar…but just in the vacuum of 3 - 5 days prior to your period…because, Why??? If that’s anecdotally true, cool. But to claim it’s based on the science of our hormones, that’s an incorrect conclusion in my book.

“Changes are due to two hormones, estrogen and progesterone. When these hormones are at their highest level just before your period, they affect another important hormone, insulin, which may, in turn, cause blood glucose to rise.”

blood sugar levels. There are 2 main hormones involved:
