If you donated your left kidney, then your adrenal gland is affected. From the research that I have done, your adrenal gland on the LEFT uses the same vein as your kidney. When you donate your kidney, they remove the vein, artery, and ureter. I may not be an MD, but I know enough about the circulatory system to know that without a working vein, that adrenal gland doesn't function properly anymore. As a note, this is note an issue on the right side of the body as the adrenal uses the superior vena cava on that side... this according to what I've read. I'm not a doc or nurse. Just so you know, I was young when I did this and I started having perimenopausal symptoms and have to take natural progesterone cream... this is a bummer and I think people in the living donor and transplant community should know that this is a potential problem. I think that the prevailing wisdom is that you can live just fine with one adrenal. My life has never returned to "normal."
