PCOS is Insulin Resistance — Not a Hormone Disorder

She was 40, hadn't had a period in two years, and was terrified she would never be able to get pregnant. Her doctors gave her a PCOS diagnosis and offered birth control — which she couldn't tolerate. What nobody checked was her TPO antibodies (236 — classic Hashimoto's), her fasting insulin (11 — early insulin resistance driving androgen excess), her gut microbiome (depleted, likely driving both conditions), or her homocysteine (elevated — impairing egg quality and embryo implantation).   In this episode, we break down Mary’s case: the three root causes of her infertility risk, the science behind each one, and the exact steps every woman with PCOS or cycle irregularities should take — starting this week. In this episode: • Why PCOS is a metabolic disorder — not a hormone disorder — and what that means for treatment  • How elevated insulin drives testosterone, suppresses ovulation, and causes amenorrhea  • Why TPO antibodies must be tested in every woman with PCOS or fertility challenges  • The fertility-specific TSH target (below 2.5) and why standard 'normal' ranges are insufficient  • The gut-autoimmunity-hormone connection: why the gut is the upstream driver  • Methylation, homocysteine, and why standard folic acid may not be enough  • The evidence for myo-inositol, selenium, gluten elimination, and GI-MAP testing  • 7 actionable steps — including the exact words to say to your doctor  Key Statistics Referenced • TPO antibodies: Hashimoto's diagnosis (optimal below 35)  • TSH: Fertility target: below 2.5  • Fasting insulin: Optimal below 6  • Vitamin D: Fertility optimal: 60-80  • Homocysteine: ＞7— elevated methylation marker (optimal below 7)  • Progesterone: Ovulatory level: above 10  • Free testosterone: 0.5 – 6.4 pg/ml (varies by lab) ＞7 consistent with androgen-driven PCOS  • Up to 80% of women with PCOS: have insulin resistance — even thin women  • Normalizing insulin sensitivity restores ovulation in up to 80% of PCOS cases without hormonal intervention  • Hashimoto's affects: approximately 1 in 8 women over their lifetime  • Elevated TPO antibodies: associated with 3-4x higher miscarriage risk even when TSH is normal  • PCOS + Hashimoto's coexist in approximately 25-30% of PCOS patients  • Gut microbiome disruption found in up to 90% of women with PCOS in microbiome studies  • Vitamin D below 30: associated with up to 40% lower IVF live birth rates  • Selenium 200 mcg/day: shown to reduce TPO antibodies significantly in meta-analyses (Check levels BEFORE supplementing)  • Gluten elimination: shown to reduce TPO antibodies by 30-50% over 6 months in Hashimoto's patients   Listen now to better understand what your body may be trying to tell you. ********************* Midlife Clarity with Dr. Tracy Page is a podcast for women over 40 navigating hormones, metabolism, strength, and healthy aging during midlife, perimenopause, and menopause.
