From Chaos to Clarity: Finding Your PCOS Type

***Disclaimer: I’m not a licensed medical professional and do not treat or diagnose illness. This content is for educational purposes only.

Why weren’t we told what type we have?

That’s such a powerful and important question — and honestly, you're not alone in wondering this. So many people with PCOS have this same experience: they leave the gynecologist’s office with a diagnosis and maybe a prescription, but not much understanding of what’s actually going on in their body — let alone that there are different types of PCOS.

Most gynecologists are trained to diagnose PCOS based on the Rotterdam criteria, which looks for 2 out of 3 signs:

  • Irregular or absent ovulation

  • Elevated androgens (testosterone)

  • Polycystic ovaries on ultrasound

This approach doesn’t differentiate between the root causes — it just checks the boxes. So if you fit the criteria, you get the label “PCOS,” but not necessarily a deeper explanation.

Once you have your history, labs, and imaging, you can classify which phenotype fits best. That in turn helps inform personalized approaches.

1. Insulin‑Resistant PCOS

Root cause: Blood sugar imbalance, insulin resistance
Common signs & symptoms:

  • Sugar cravings, especially after meals or around your period

  • Feeling tired after eating, or needing a nap after carbs

  • Weight gain (especially around the belly), difficulty losing weight

  • Skin tags, dark patches of skin (especially neck/armpits)

  • Acne, especially along jawline/chin

  • Irregular cycles, long cycles, or missed periods

  • Mood swings or “hangry” crashes when you go too long without food

✨ This is the most common type — and it’s often improved with blood sugar-stabilizing foods, mindful movement, and herbal/metabolic support.

Mechanism: Excess insulin drives ovarian androgen production and disrupts follicle development.
Clues:

  • Acanthosis nigricans (darkened skin folds)

  • Family history of type 2 diabetes

  • Central (“apple‑shaped”) adiposity

How to test:

  1. Fasting insulin and glucose → calculate HOMA‑IR

  2. Oral Glucose Tolerance Test (OGTT) with insulin measurements at 0, 30, 60, 90, 120 minutes

  3. Hemoglobin A1c (for longer‑term glycemic control)

2. Adrenal PCOS

Root cause: Elevated DHEA-S from adrenal (stress-related) hormone imbalance
Common signs & symptoms:

  • You have high androgens (acne, hair loss, hirsutism) but normal insulin + ovarian markers

  • Sensitive to stress, overstimulation, or burnout

  • “Tired but wired” feeling, sleep issues, cortisol spikes

  • Lean body type or normal weight

  • You feel emotionally drained or edgy often

  • Cycles might be irregular, but not absent

✨ This type is less about food and more about nervous system healing — breathwork, rest, sleep, somatic work, and adrenal-nourishing herbs like ashwagandha or holy basil.

Mechanism: Overproduction of DHEA‑S and other adrenal androgens, often linked to chronic stress or HPA‑axis dysregulation.
Clues:

  • Predominant elevations in DHEA‑S (vs. testosterone)

  • History of chronic stress, insomnia, or adrenal fatigue symptoms

How to test:

  1. Serum DHEA‑S (often > 600 μg/dL)

  2. 24‑hour urinary adrenal androgen profile (e.g., DHEA, androsterone, etiocholanolone)

  3. Salivary cortisol rhythm (morning, midday, evening) to assess HPA‑axis balance

3. Inflammatory (Post‑Inflammatory) PCOS

Root cause: Chronic low-grade inflammation
Common signs & symptoms:

  • Fatigue that doesn’t improve with rest

  • Joint pain or muscle soreness

  • Skin issues like eczema, psoriasis, or acne that flares with stress or certain foods

  • Digestive issues (bloating, constipation, IBS-like symptoms)

  • You feel puffy or swollen often

  • Irregular cycles, PMS, and ovulation pain

  • Heightened sensitivity to stress or certain foods (dairy, gluten, sugar)

✨ Often linked with a gut-immune connection. A great place to start is anti-inflammatory foods, digestive support, and nervous system regulation.

Mechanism: Chronic low‑grade inflammation (e.g., from gut dysbiosis, food sensitivities) contributes to insulin resistance and androgen excess.
Clues:

  • Elevated markers of inflammation (CRP, IL‑6)

  • Digestive symptoms, history of antibiotic use, food reactions

How to test:

  1. High‑sensitivity CRP (hs‑CRP)

  2. Cytokine panel (IL‑6, TNF‑α) if available

  3. Comprehensive stool analysis (gut microbiome, markers of dysbiosis)

4. Post‑Pill PCOS

Root cause: Hormonal rebound after coming off the pill
Common signs & symptoms:

  • You had regular cycles before the pill, but after stopping, your periods vanished or became irregular

  • Breakouts flared months after stopping birth control

  • Hair loss, especially around the temples

  • PMS and mood swings since coming off the pill

  • Often thinner body types, not always insulin resistant

  • Can be mistaken for other PCOS types — but timing is key

✨ Usually resolves with time, but the transition can be rocky. Supporting liver detox, hormone metabolism, and nutrient replenishment (zinc, B6, magnesium) is key.

Mechanism: Dysregulation of the HPO‑axis after coming off hormonal birth control, leading to transient anovulation or androgen imbalance.
Clues:

  • History of ≥ 6 months on combined oral contraceptives

  • Irregular cycles or breakthrough androgenic symptoms after stopping

How to test:

  1. Wait 3 months off hormones (to allow HPO‑axis reset) before testing

  2. Baseline labs on cycle day 3 (if periods have resumed) or any day (if amenorrheic):

    • FSH, LH, estradiol

    • Total and free testosterone, DHEA‑S

  3. Ultrasound for PCOM features (if cycles remain irregular)

Using the Rotterdam Criteria Alongside Subtyping

Regardless of subtype, you confirm PCOS diagnosis by demonstrating two of three Rotterdam features and ruling out mimickers (thyroid disease, hyperprolactinemia, nonclassic CAH, androgen‑secreting tumors, Cushing’s).

  1. Clinical/lab evaluation for hyperandrogenism

  2. Menstrual history or ovulation tracking

  3. Transvaginal ultrasound for ovarian structure

Together, your Rotterdam diagnosis anchors the PCOS label, while subtype testing (insulin, adrenal, inflammatory, post‑pill) steers a personalized treatment plan.

***Bonus Tip: You can have more than one type — like inflammation and insulin resistance, or post-pill that reveals underlying stress patterns.
