Hi, I am new to forum and please forgive my newbie questions but also please help! My novice understanding from reading so far on this topic = estrogen alway bad. So why does it decrease in women as we age and does it serve a purpose at all in the body? Energy, etc? Of course the doctor listed horrific diseases and conditions that would surely befall if estrogen not supplemented and I'm not falling for this. However, my only question that persists is...if the young hold the standard for healthy levels and the young woman has higher estrogen, how is my low level good? Hormones work together to balance, yes? Please help me understand or direct me to the articles to read. Thanks so much!!!
