PCOS Treatment in a 22-Year-Old Unmarried Female

Goals of Treatment (Non-Fertility Focus)

1. Menstrual cycle regulation - protect the endometrium
2. Hyperandrogenism control - acne, hirsutism, androgenic alopecia
3. Metabolic health - insulin resistance, dyslipidemia, weight
4. Psychological wellbeing - depression, body image
5. Long-term risk reduction - endometrial hyperplasia/cancer, cardiovascular disease, T2DM

Step 1: Lifestyle Modification (FIRST LINE - Everyone)

• Diet: Reduced-energy diet (500-1000 kcal/day reduction), low glycemic index, <30% calories from fat, high fiber, whole grains, fruits and vegetables
• Exercise: >30 min/day structured aerobic + resistance activity; improves insulin resistance independently of weight loss
• Weight loss: Even a 5-10% reduction in body weight in overweight/obese women significantly improves menstrual regularity, androgen levels, and metabolic parameters
• Stress management and behavioral modification included

Step 2: Pharmacological Treatment

A. Combined Oral Contraceptive Pills (COCPs) - First-Line Drug Therapy

• Androgens decrease within 2-3 months
• Choose pills with anti-androgenic or low-androgenic progestins:
  • Drospirenone (e.g., Yasmin/Yaz) - has anti-androgenic + anti-mineralocorticoid properties
  • Desogestrel, gestodene, norgestimate - low androgenic activity
  • Avoid norgestrel, norethindrone, norethindrone acetate (androgenic progestins)
• Also provides endometrial protection against hyperplasia (from chronic anovulation)

B. Metformin - For Insulin Resistance

• Oral biguanide; inhibits hepatic gluconeogenesis + increases peripheral glucose uptake
• Reduces insulin resistance, may restore spontaneous ovulation
• Dose: Start low - 500 mg OD with food → titrate up to 500 mg TDS or 850 mg BD or 1000 mg BD over weeks
• Extended-release (Metformin XR) has fewer GI side effects
• Important: Does not replace endometrial protection - if still anovulatory, periodic progestin-induced withdrawal bleeds are needed
• Benefits: modest weight loss, improvement in hyperandrogenism, reduced progression to T2DM

C. Spironolactone - For Hirsutism/Acne (Add-on or Alternative)

• Mechanism: Competitive androgen receptor blockade + inhibits 5α-reductase + suppresses testosterone synthesis
• Dose: 50-100 mg twice daily (up to 200 mg/day)
• Improvement in hirsutism begins at 3-6 months; maximal effect at 12 months
• 70-80% of women show at least modest improvement with ≥100 mg/day for 6 months
• Almost always combined with a COCP (synergistic + prevents menstrual irregularity that spironolactone causes)
• Key counseling point: Teratogenic (feminization of male fetus) - hence MUST use contraception. In unmarried women, always pair with a COCP
• Monitor potassium and creatinine periodically

D. For Acne (Additional Options)

• COCPs with drospirenone are effective for acne
• Topical retinoids, benzoyl peroxide for mild-moderate acne
• Oral antibiotics (doxycycline) for moderate-severe acne as bridge while waiting for hormonal effect
• Spironolactone 50-100 mg/day is effective for hormonal acne
• Isotretinoin for severe, refractory acne (requires pregnancy exclusion/contraception - coordinate with gynaecologist)

E. Inositol (Emerging/Adjunctive)

• Menstrual regularity
• Insulin resistance
• Androgen levels
• Ovarian function

Step 3: Monitoring & Investigations at Baseline

Summary Algorithm for a 22-Year-Old Unmarried Female

All patients → Lifestyle modification (diet + exercise)
     |
     ├── Menstrual irregularity + Acne/Hirsutism
     |        → COCP with anti-androgenic progestin (drospirenone preferred)
     |           ± Spironolactone 50-100mg BD if hirsutism prominent
     |
     ├── Metabolic concerns (obesity, IR, prediabetes)
     |        → Metformin (start 500mg OD, titrate to 1500-2000mg/day)
     |           + COCP if also anovulatory
     |
     ├── Both hormonal + metabolic
     |        → COCP + Metformin ± Spironolactone
     |
     └── Doesn't want hormonal pills
              → Metformin + Inositol + periodic progesterone
                (medroxyprogesterone 10mg × 10-14 days every 1-3 months)
                to induce withdrawal bleed + protect endometrium

Psychological Wellbeing

Long-Term Considerations

• Risk of endometrial hyperplasia/cancer is 2-6x higher with chronic anovulation - endometrial protection (COCPs or cyclic progesterone) is non-negotiable
• Annual/biennial monitoring of glucose, lipids
• PCOS symptoms often improve in the 30s-40s as LH pulsatility and androgen levels decrease with age
• Counsel about future fertility implications - ovulation induction (clomiphene, letrozole) available when pregnancy is desired, and early treatment now does not compromise future fertility
