We discuss the differences between bio-identical hormone replacement therapy (BHRT) and conventional hormone replacement therapy (HRT). We discuss why BHRT is better than HRT, when someone should have their hormones tested, and the long-term issues if hormones remain out of balance. We also address the link between hormones, specifically how thyroid hormone and our sex hormones are linked as well as how our sex hormones affect inflammation in the body. We cover the benefits of BHRT for brain, bones, breast tissue, and our heart as well as common improvements seen in people receiving BHRT.
