I also had my uterus removed at age 35 because of heavy bleeding. But I never had hot flashes and had no idea when I went through menopause. I was later told that the menopause comes immediately after the surgery. I was not given estrogen at that time. I suffered depression knowing I could not have more children. The hot spells came with the tamoxifen which I took after breast cancer surgery. I quit that after six months so I could sleep at night. Now at age 84 I have hot spells, mostly at night and go out on my little porch by the bedroom to cool off, not knowing what is causing the problem or what to do about it. Now I am working on a better night's sleep considering that I make three or four trips to the bathroom each night. Sometimes I am hungry in the night. I am working on it. Dorisena
