Quick Answer: PCOS affects 1 in 10 women and is manageable through lifestyle changes (5-10% weight loss significantly improves symptoms), medications (metformin, birth control), and supplements (inositol 2000-4000mg daily). Key strategies: low-GI diet, regular exercise, stress management, and targeted medical treatment based on your symptoms. While there's no cure, 70-80% of women see major improvement with comprehensive management.
If you've been diagnosed with PCOS or suspect you have it, you're not alone. Polycystic Ovary Syndrome affects 8-13% of reproductive-age women, yet up to 70% remain undiagnosed. The good news? PCOS is highly manageable when you understand it and take the right approach. Let me break down everything you need to know.
What Is PCOS?
PCOS is a hormonal disorder involving multiple systems in your body, primarily affecting your ovaries, metabolism, and hormone production.
The Core Problems in PCOS:
- Insulin resistance: 70-80% of women with PCOS have this
- Elevated androgens: Higher "male" hormones (testosterone, DHEA-S)
- Irregular ovulation: Eggs don't release regularly or at all
- Inflammation: Chronic low-grade inflammation
- Hormonal imbalance: Disrupted LH/FSH ratio
Why "Polycystic"?
Despite the name, you don't always have cysts. The "cysts" are actually multiple immature follicles (developing eggs) that never matured and released. Many women with PCOS don't even have these on ultrasound.
Important to know: PCOS is a syndrome (collection of symptoms), not a single disease. This means it presents differently in each woman and requires personalized treatment. You might have different symptoms than your friend with PCOS.
PCOS Symptoms: What to Look For
Common PCOS Symptoms:
- Irregular periods: Cycles longer than 35 days, fewer than 8 periods/year, or absent periods
- Excess hair growth (hirsutism): Dark hair on face, chest, back, or abdomen
- Acne: Persistent, often along jawline and chin
- Weight gain: Especially around abdomen, difficult to lose
- Thinning hair: Male-pattern hair loss on scalp
- Dark skin patches: Acanthosis nigricans (neck, armpits, groin)
- Skin tags: Small excess flaps of skin
- Difficulty getting pregnant: Irregular or absent ovulation
- Mood changes: Depression, anxiety more common
Not Everyone Has All Symptoms:
You might have irregular periods but no acne. Or excess hair but regular cycles. PCOS presents differently in each woman.
PCOS Types:
- Insulin-resistant PCOS: Most common (70%), weight gain, dark skin patches
- Inflammatory PCOS: Chronic inflammation markers, headaches, joint pain
- Post-pill PCOS: Symptoms emerge after stopping birth control
- Adrenal PCOS: High DHEA-S, stress-related
How Is PCOS Diagnosed?
Rotterdam Criteria (Most Common):
You need 2 out of 3 of these:
- Irregular ovulation: Absent or irregular periods
- Elevated androgens: High testosterone or clinical signs (excess hair, acne)
- Polycystic ovaries: 12+ follicles per ovary on ultrasound
Tests Your Doctor May Order:
- Blood tests:
- Testosterone (total and free)
- DHEA-S
- LH and FSH (LH:FSH ratio often 2:1 or higher)
- Fasting insulin and glucose
- HbA1c (3-month blood sugar average)
- Thyroid function (TSH, free T4)
- Prolactin
- 17-hydroxyprogesterone (rule out other conditions)
- Pelvic ultrasound: To visualize ovaries
- Additional tests: Lipid panel, vitamin D, inflammatory markers
Conditions to Rule Out:
- Thyroid disorders
- Cushing's syndrome
- Congenital adrenal hyperplasia
- Hyperprolactinemia
Important: PCOS diagnosis can take time and multiple visits. If your doctor dismisses your concerns or doesn't run comprehensive tests, seek a second opinion. PCOS is often underdiagnosed, especially in lean women.
What Causes PCOS?
The exact cause isn't fully understood, but multiple factors contribute:
1. Genetics
- 50% of sisters of women with PCOS also have it
- If your mother has PCOS, you're at higher risk
- Multiple genes involved, not just one
2. Insulin Resistance
- Cells don't respond well to insulin
- Pancreas produces more insulin to compensate
- High insulin triggers ovaries to produce more androgens
- Creates vicious cycle of hormonal imbalance
3. Inflammation
- Chronic low-grade inflammation
- Stimulates ovaries to produce androgens
- Can worsen insulin resistance
4. Lifestyle Factors
- Poor diet (high refined carbs, sugar)
- Sedentary lifestyle
- Chronic stress
- Sleep deprivation
- Endocrine disruptors (BPA, phthalates)
Medical Treatment Options for PCOS
1. Birth Control Pills
- How they help: Regulate periods, reduce androgens, improve acne/hair
- Best for: Not trying to conceive, need period regulation
- Common options: Combination pills with anti-androgen progestins (drospirenone, cyproterone)
- Pros: Regulates cycles, reduces symptoms
- Cons: Masks symptoms (doesn't treat root cause), not for pregnancy attempts
2. Metformin
- How it helps: Improves insulin sensitivity
- Dose: 500-2000mg daily (extended-release preferred)
- Benefits:
- Improves insulin resistance
- Can restore ovulation
- Aids weight loss
- Reduces diabetes risk
- Side effects: GI upset (start low, increase slowly)
- Note: Take with B12 supplement (metformin depletes B12)
3. Anti-Androgens
- Spironolactone: 50-200mg daily for excess hair/hair loss
- Finasteride: Sometimes used for hair loss
- Benefits: Reduces hirsutism, hair loss, acne
- Takes time: 6-12 months to see full hair effects
4. Fertility Medications (If Trying to Conceive)
- Clomid (clomiphene): Stimulates ovulation
- Letrozole: Often more effective than Clomid for PCOS
- Gonadotropins: Injectable hormones for ovulation
- IVF: If other methods unsuccessful
5. Other Medications
- GLP-1 agonists: Ozempic, Mounjaro (for weight management)
- Eflornithine cream: For facial hair
- Retinoids: For acne
PCOS Diet: What to Eat and Avoid
Best Diet Approaches for PCOS:
1. Low Glycemic Index (GI) Diet
- Focus: Foods that don't spike blood sugar
- Eat: Whole grains, legumes, non-starchy vegetables
- Avoid: White bread, white rice, sugary foods
- Research: Improves insulin sensitivity, promotes weight loss
2. Mediterranean Diet
- Focus: Whole foods, healthy fats, lean protein
- Eat: Vegetables, fruits, olive oil, fish, nuts, whole grains
- Research: Reduces inflammation, improves insulin sensitivity
3. Low-Carb or Ketogenic
- Focus: Reduced carbohydrates
- Carb intake: 50-150g daily (low-carb) or <50g (keto)
- Research: Can be very effective for insulin resistance
- Note: May be harder to sustain long-term
Foods to Emphasize:
- Protein: Chicken, fish, eggs, tofu, legumes
- Non-starchy vegetables: Leafy greens, broccoli, peppers, cauliflower
- Healthy fats: Avocado, nuts, seeds, olive oil, fatty fish
- Complex carbs: Quinoa, oats, sweet potato, legumes
- Anti-inflammatory foods: Berries, turmeric, ginger, green tea
- High-fiber: Aim for 25-30g daily
Foods to Limit or Avoid:
- Refined carbs: White bread, pasta, pastries
- Sugary foods: Candy, soda, juice, desserts
- Processed foods: Packaged snacks, fast food
- Excessive dairy: May worsen symptoms in some women
- Trans fats: Fried foods, margarine
- Alcohol: Excessive consumption
Meal Timing and Frequency:
- 3 balanced meals or 5-6 smaller meals
- Don't skip breakfast
- Include protein at each meal
- Avoid long fasting periods (can worsen hormones in some women)
Important: There's no single "PCOS diet." What works is highly individual. Many women benefit from working with a registered dietitian who specializes in PCOS to create a personalized plan.

Common Questions About PCOS
Can PCOS go away?
PCOS is a lifelong condition, but symptoms can be managed and may improve significantly with treatment. Some women experience symptom reduction after menopause. With lifestyle changes, many women become virtually symptom-free.
Can you have PCOS with regular periods?
Yes, though less common. You can have PCOS with regular cycles if you meet the other criteria (elevated androgens and/or polycystic ovaries). This is sometimes called "ovulatory PCOS."
Can thin women have PCOS?
Absolutely. About 20-30% of PCOS women are lean. "Lean PCOS" has the same hormonal issues but without weight gain. Treatment is similar but focuses less on weight loss.
Will losing weight cure PCOS?
Weight loss won't cure PCOS, but 5-10% weight loss can dramatically improve or even resolve many symptoms. Ovulation often restores, androgens decrease, and insulin sensitivity improves.
Should I avoid all carbs with PCOS?
No need to eliminate carbs entirely. Focus on quality: choose complex carbs with fiber, pair with protein/fat, and avoid refined carbs. Many women do well with moderate carb intake (100-150g daily).
The Bottom Line on PCOS
Key Takeaways:
- PCOS affects 1 in 10 women but is highly manageable with right approach
- Lifestyle changes (diet, exercise, stress management) are foundational
- 5-10% weight loss dramatically improves symptoms if overweight
- Inositol (2000-4000mg daily) is most evidence-based supplement
- Low-GI or Mediterranean diet works well for most women
- Medications (metformin, birth control) help when lifestyle isn't enough
- Most women with PCOS can get pregnant with proper treatment
- Early management prevents long-term complications like diabetes
Being diagnosed with PCOS can feel overwhelming, but remember: this is one of the most manageable hormonal conditions. Unlike many health issues, you have significant control through lifestyle choices. The combination of proper diet, exercise, stress management, and targeted supplements or medications can transform your symptoms.
Don't expect overnight results. PCOS management is a journey, often requiring 3-6 months to see significant improvements. But the effort is worth it—most women report dramatic symptom improvement and better quality of life with comprehensive management.
Work with healthcare providers who understand PCOS (endocrinologist, reproductive endocrinologist, or PCOS-specialized doctor). Track your symptoms, be patient with yourself, and celebrate small victories along the way.
