I had a radical hysterectomy done 9 years ago. Since that time I have gained weight that I cannot lose, my cholesteral level has risen to a danger zone and now take medication also B12 injections. I suffer from fatigue, memory loss, cold sensitivety and other problems. I recently had a FSH test done and was told the levels indicate I am still producing estrogen. How is this possible if I have no ovaries and what can I do to find out why
