Why understanding your hormones changes everything

In this episode, Dr Louise Newson is joined by Professor Mary Ryan, Consultant Endocrinologist, Adjunct Associate Professor at Trinity College Dublin and author of It’s Probably Your Hormones. Together, they explore why hormones are far more than just “reproductive messengers”, and how they influence almost every system in the body, including the brain, immune system, metabolism, bones and cardiovascular health. The conversation moves through perimenopause, menopause, autoimmune disease, thyroid conditions, PCOS, endometriosis and fertility, highlighting how hormone imbalance is often overlooked or misunderstood in both research and clinical practice. This episode is a reminder that when we understand hormones properly, we don’t just treat symptoms. We change long-term health, quality of life and outcomes for women, as well as for society as a whole.
