I have just read your post re hot flushes being due to high estrogen and low progesterone. I can't understand why this would be the case. I previously used Natpro to alleviate symptoms of estrogen dominance - swollen breasts, weight gain, fibroids - was still having regular periods. Now, I'm a little older and my last period was about 6 months ago. I am having hot flushes night and day. It seems obvious to me that something has changed - ie a drop in estrogen. Why, if it was low progesterone, would I have not had hot flushes two years ago when my progesterone levels were very low and estrogen normal?
