View the Show Notes For This Episode PCOS Renamed PMOS: Root Causes, Hormones, Metabolism, Labs, and Integrative Treatment with Dr. Felice Gersh Dr. Ben Weitz introduces an interview with OB-GYN and integrative physician Dr. Felice Gersh on PCOS, newly renamed polyendocrine metabolic ovarian syndrome (PMOS) per a May 12, 2026 Lancet announcement, meant to shift focus from "cysts" to hormonal and metabolic dysfunction. Gersh argues ovaries remain central, describing impaired aromatization leading to low estradiol, high LH-driven testosterone, and downstream effects including insulin resistance, inflammation, leaky gut, altered microbiome, sympathetic activation, elevated cortisol/DHEAS, obesity, mood disorders, sleep apnea, and autoimmune risk. They discuss legacy and practical issues with renaming, updated diagnostic criteria adding anti-Müllerian hormone in adults, and PMOS as a diagnosis of exclusion. Recommended evaluation includes total testosterone, DHEAS, SHBG, thyroid panel with antibodies, lipids including apoB, hsCRP, nutrients, ANA, prolactin, and select rule-outs (17-OHP, Cushing's, tumors). Treatment emphasizes lifestyle, plant-focused diet, time-restricted eating, exercise, supplements (myo-inositol, NAC, quercetin, melatonin, mitochondrial support), cautious pharmaceuticals (metformin/berberine, spironolactone), and cyclic bioidentical estradiol/progesterone; low-dose dexamethasone is noted for select adrenal-driven cases. 01:02 PCOS Renamed PMOS 04:51 Hormone Pathway Explained 09:04 Systemic Effects Cascade 13:15 Prevalence And Risks 17:29 Name Change Debate 18:28 Follicles And AMH 22:54 Inflammation And Immunity 26:17 Origins And Modern Triggers 31:40 Why Rebranding Falls Short 35:05 PCOS PMOS Searchability 35:48 Updated Diagnostic Criteria 37:52 Teen vs Adult Criteria 39:01 Key Lab Workup 44:07 High DHEAS Red Flags 45:00 Diagnosis of Exclusion 47:39 Lifestyle Treatment Plan 49:16 Diet and Fasting Strategies 53:45 Meds and Herbal Options 54:43 Mitochondria and Supplements 57:54 Inositol Ratio Debate 01:00:47 Hormones and Antiandrogens 01:04:03 Adrenal DHEAS Suppression Dr. Felice Gersh is a board certified obstetrician and gynecologist and she is also fellowship-trained in Integrative Medicine.
