Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders affecting women of reproductive age. Yet it remains one of the most misunderstood and underdiagnosed medical conditions.1
Experts have come to recognize that PCOS is not the same for every woman. Instead, it is a complex, multifaceted syndrome driven by distinct underlying mechanisms that vary dramatically from person to person.
To truly heal, we must identify your specific physiologic driver. By uncovering your unique PCOS type, we can transition away from generic treatments and construct a laser-focused plan that supports your body’s specific needs.
Did the Name “PCOS” Change?
A frequent point of confusion (and distress) for many women and healthcare providers is the name “polycystic ovary syndrome”. They immediately visualize large, painful ovarian cysts that might require surgical intervention. This leads patients to focus on seeking gynecologic care, even if the specific PCOS type they have may require a different approach.
The name is also misleading because it implies that polycystic ovaries are the cause, when they’re simply associated with it.
In fact, the “cysts” aren’t true ovarian cysts at all; they are merely small, underdeveloped, fluid-filled follicles that have stalled in their maturation process due to hormonal imbalances.2
Because an egg is not properly selected and released during an ovulatory cycle, these tiny follicles accumulate along the outer edge of the ovary, presenting a “string of pearls” appearance on ultrasound. These cysts aren’t composed of abnormal or cancerous cells, which is another common misconception.3
For years, international medical organizations, clinicians, patients, and advocacy groups have advocated for a name change to reflect the true multifaceted, systemic nature of this condition. Recently, proposals have been put forth by major scientific institutions and advocacy groups to rename PCOS “polyendocrine metabolic ovarian syndrome,” or PMOS, to better encapsulate its multisystemic nature.4
While official diagnostic codes still use “PCOS” for now, the shifting language highlights a clinical reality: we must treat this as a systemic metabolic imbalance, not an isolated gynecologic issue. Aligning the terminology with evolving science will help enhance care quality, patient experience, and health outcomes.5
PCOS Phenotypes vs. Functional Types: Can You Have More Than One?
Currently, clinical diagnosis relies on the Rotterdam criteria, which were developed by experts in 2003.6 To be diagnosed with PCOS, a patient must present two of the following three features:
- Ovulatory dysfunction (irregular or absent periods)
- Hyperandrogenism (elevated blood levels of androgens or clinical signs like male-pattern hair growth)
- Polycystic ovaries on an ultrasound
- Phenotype A (classic PCOS): Displays significant symptoms associated with all three features: ovulatory dysfunction, hyperinsulinemia, insulin resistance, and increased risk of metabolic complications.
- Phenotype B (also called classic PCOS): Displays hyperandrogenism and ovulatory dysfunction but features normal ovarian morphology on ultrasound.
- Phenotype C (ovulatory PCOS): Displays slightly high insulin, androgen, and lipid profiles as well as polycystic ovaries, but the patient doesn’t display ovulatory dysfunction.
- Phenotype D (non-hyperandrogenic PCOS): Displays intermittent ovulatory dysfunction and polycystic ovarian morphology but has normal blood androgen levels. Patients with this phenotype may have a lower LH/FSH (luteinizing hormone/follicle-stimulating hormone) ratio, with altered levels of thyroid hormones (T3 and T4).
- Insulin-resistant PCOS
- Inflammatory PCOS
- Post-pill PCOS
- Adrenal PCOS
- Lean PCOS
A Comprehensive Approach to Diagnostic Testing
To identify your specific PCOS phenotype and underlying key drivers, we must rely on targeted, comprehensive laboratory testing. Relying solely on a basic screening panel often misses subtle hormonal and metabolic shifts that may drive PCOS. Remember, PCOS should not be diagnosed by ultrasound alone. A thorough diagnostic workup should include the following:
- Fasting insulin, fasting glucose, and HOMA-IR: Testing insulin alongside glucose allows us to calculate the homeostatic model assessment for insulin resistance (HOMA-IR). This identifies hidden insulin resistance years before standard glucose tests show any problems.
- Hemoglobin A1C (HbA1c): This biomarker shows your average blood sugar levels over the last 90 days, helping to ensure they are stable and reducing the risk of diabetes.
- Liver enzymes (ALT, AST, GGT): Non-alcoholic fatty liver disease (NAFLD) occurs frequently in patients with PCOS.8 Therefore, it’s critical to perform regular liver function screens.
- hs-CRP, ESR, ferritin, and 8-OHdG: High-sensitivity C-reactive protein (hs-CRP) and erythrocyte sedimentation rate (ESR) measure systemic inflammation. High levels of ferritin can signify abnormal iron storage, indicating inflammation.9 8-hydroxy-2′-deoxyguanosine (8-OHdG) can reflect low levels of oxidative damage, which can lead to inflammation.10 Chronic inflammation impairs insulin receptors, contributing to insulin resistance.11
- Full thyroid panel (TSH, free T4, free T3, anti-TPO, anti-TG): Research shows a higher prevalence of autoimmune thyroid diseases (like Hashimoto’s thyroiditis) in women with PCOS.12 A full thyroid panel can rule out thyroid dysfunction.
- Progesterone: Checking progesterone levels during your luteal phase helps us confirm whether ovulation is taking place.
- DHEA and DHEA-S: Dehydroepiandrosterone sulfate (DHEA-S) is a type of androgen produced almost exclusively by your adrenal glands. Measuring it allows us to differentiate between adrenal hyperandrogenism and ovarian hyperandrogenism.
- Cortisol curve and clearance (DUTCH test): This test allows us to view the cortisol awakening response (CAR), daily cortisol curves, and the liver’s clearance rate of adrenal metabolites.
- Total androgen profile (total and free testosterone, DHT, SHBG, androstenedione): This complete panel measures levels of androgens and sex hormone-binding globulin (SHBG), the protein that dictates how much free, active testosterone is available in your body.
Designing Your Laser-Focused Support Plan for Your PCOS Phenotype
Once we’ve performed comprehensive lab tests and charted your unique clinical history, we can design a targeted treatment plan. Your plan includes lifestyle, nutritional, and herbal therapies targeted directly to your key functional drivers.
Insulin-Resistant PCOS
Insulin resistance is the most prevalent functional driver, underlying a majority of all classic PCOS cases.13 In insulin-resistant PCOS, higher than normal levels of insulin in the body (hyperinsulinemia) can lead to your cells becoming “numb” to insulin’s effects. This forces the pancreas to produce more and more insulin to keep blood glucose levels stable. In turn, excess insulin can contribute to chronic inflammation.
High levels of circulating insulin also act directly on the ovaries, stimulating theca cells (a group of cells in the ovary) to overproduce testosterone while suppressing SHBG production in the liver.14,15 This leaves more free testosterone available to cause tissue damage, abdomen fat accumulation, and ovulatory dysfunction.16
Key factors to support your body include:
- Regular exercise: Focus on building lean muscle mass, which acts as a storage site for glucose, thereby lowering insulin requirements. A continuous glucose monitor can provide insight into your metabolic flexibility.
- Nutritional and herbal interventions: Focus on achieving metabolic flexibility. Integrating safe intermittent fasting patterns can allow insulin levels to drop to a baseline rest state. Key supplements include inositol and berberine, which work to improve insulin signaling and enhance insulin sensitivity.17,18 Vitamin D can help to protect pancreatic function.
- Circadian foundations: Prioritizing deep sleep and establishing consistent circadian light exposure is vital, as a single night of sleep deprivation can increase insulin resistance the next day.19
Inflammatory PCOS
Chronic inflammation can trigger excess androgen production, disrupting hormonal balance and leading to symptoms like weight gain, irregular periods, and ovarian cysts. Individuals with inflammatory PCOS may also experience symptoms like chronic fatigue, digestive issues, and environmental or chemical sensitivities.
Key factors to support your body include:
- Identify upstream drivers: Identify and remove “upstream drivers,” or core causes, of inflammation. This involves comprehensive gut health assessments to rule out conditions like leaky gut and screening for underlying autoimmune conditions. Try to minimize your exposure to heavy metals and common endocrine-disrupting chemicals (EDCs).
- Herbal and nutritional therapies: Eat an anti-inflammatory diet rich in phytonutrients, wild-caught fish, and polyphenols. Targeted herbal and nutritional support include green tea extract (EGCG), curcumin, and omega-3 fatty acids.
- Cold therapy: Incorporating regular cold plunging or cold therapy can help down-regulate inflammatory cytokine production.20
- Comprehensive detoxification support: Supporting your liver’s detoxification pathways ensures that circulating inflammatory mediators and inactive hormones are safely bound and eliminated.
Post-Pill PCOS
Stopping the use of oral contraceptives can cause a surge in androgens, leading to temporary symptoms like irregular periods. This happens because the synthetic progestins in oral contraceptives suppress communication between your brain and your ovaries. When the pill is removed, your body can experience a temporary inability to kickstart natural ovulation.
Key factors to support your body include:
- Reestablishing rhythm: Reestablish the delicate communication loop between the brain and ovaries. Short-term progesterone supplementation can be useful here. Vitex agnus-castus (chasteberry) is a great choice for reestablishing this rhythm, as it gently regulates LH production and encourages progesterone synthesis.
- Androgen and nutrient balance: Reishi mushroom, spearmint leaf tea, nettle root, and white peony can help manage the temporary androgen surge. Ensure there aren’t any underlying micronutrient deficiencies (such as zinc, B vitamins, and magnesium).
Adrenal PCOS
In this PCOS type, excess androgens (primarily DHEA-S) and cortisol are produced by the adrenal glands (rather than the ovaries) in response to chronic stress. Patients may not display insulin resistance or metabolic abnormalities.
Key factors to support your body include:
- Nervous system regulation: The primary goal here is to calm a hyperactive nervous system rather. Schedule daily outdoor time and structured breathwork (such as box breathing).
- Stress management and herbal therapies: Stress management, coupled with calming herbal adaptogens and nervines (such as ashwagandha and holy basil), can help balance your HPA axis.
- Blood sugar balance: Blood sugar regulation can help prevent cortisol spikes caused by hypoglycemia.
- Mineral support: Supporting your body with adequate amounts of minerals (like magnesium glycinate and trace minerals) ensures your adrenal glands have adequate nutrients to self-regulate.
Lean PCOS
Lean PCOS occurs in women who have a normal or low body mass index (BMI). While they may not match the stereotypical clinical image of PCOS, these women can have an elevated LH-to-FSH ratio, low progesterone, subtle insulin resistance, and/or low-grade inflammation.
Key factors to support your body include:
- Nutrient-dense support: People with lean PCOS require a nutrient-dense diet that provides adequate healthy fats and clean proteins to support ovulation. I recommend cycle syncing, a practice that encourages tailoring specific nutritional inputs to match the different phases of your menstrual cycle.
- Hormonal smoothing: Progesterone can be used to rebalance the estrogen dominance that can arise from missing cycles.
- Herbal therapies: A combination of white peony (Paeonia lactiflora) and licorice root (Glycyrrhiza glabra) works synergistically to stimulate aromatase activity. This safely encourages the conversion of excess androgens into estrogens to support ovulation.
