For me personally, as a very lean 45-year-old woman, estrogen dominance is just not a problem for me, in fact it's the opposite. PEAT and Georgi maybe correct as far as unhealthy, overweight, individuals with pre-existing conditions regarding estrogen and cortisol issues, but for me this simply hasn't been the case.
I’ve been questioning for some time now if my life-long leanness plays a role in my experience with progesterone, which seems to be in the minority here. My doctor put me on bio-identical estrogen just after my spine collapsed and it was the first time in my life I experienced depression—to the point that I almost committed suicide—and it completely vanished as soon as I stopped taking it (against my doctor’s wishes) so I know estrogen is not good for me, but as I’ve mentioned in the Female Corner thread, progesterone gives me an uncomfortably high libido even at small doses, and I only know of two other women here who shared the same experience, and they were in their 20s, which I am not. It also causes me to menstruate every two weeks. Like you, LadyRae, I’ve always been thin at 99 lb (45 kg), and dangerously underweight when I was ill—67 lb (30 kg) at my lowest—I’ve never had high prolactin, in fact, it was as low as 7 at one point, so I’m doubtful that my estrogen stores are high. What I actually needed was thyroid. It made everything better for me, and I only wish I had been able to convince my doctors to prescribe it to me sooner, but my condition flew under the radar because I’m thin.
