Ep. 504 The Pill Changes Your Brain – The Shocking Truth About Birth Control & Mental Health with Dr. Sarah Hill

Today, I am thrilled to be joined by Dr. Sarah Hill, an award-winning researcher, professor, and leading voice in the field of women’s hormones and brain health. She wrote This Is Your Brain on Birth Control and has also authored The Period Brain , which is due to be released this fall. In our conversation, Dr. Hill dispels the myths surrounding bioidentical hormones and shares her view on how women are not biologically disordered, but just ignored by science. We dive into research on how oral contraceptives affect the brain and how the pill creates a dysregulated stress response, particularly in women with histories of adverse childhood experiences. We also explore progesterone through the lens of an evolutionary biologist and neuro-endocrinologist, highlighting its role in supporting GABAergic tone, the key differences between synthetic progestins and natural progesterone, and research on PMS and PMDD, including practical ways to manage those issues. This helpful discussion with Dr. Sarah Hill is a must-listen for women at every stage of life. IN THIS EPISODE, YOU WILL LEARN: Why has science ignored women?
