Treatment Options for Polycystic Ovary Syndrome (PCOS)
The first-line treatment for PCOS should be lifestyle interventions focusing on a balanced dietary approach with an energy deficit of 30% or 500-750 kcal/day, combined with regular physical activity of at least 60 minutes daily. 1
Lifestyle Interventions
Lifestyle modifications form the cornerstone of PCOS management, particularly for patients who are overweight or obese:
Dietary Recommendations:
- Low glycemic index foods
- Anti-inflammatory diet patterns
- Adequate magnesium and zinc intake
- Limit calories from fat to 25-30%
- Limit saturated fat to <7%
- Avoid trans fats 1
- Target caloric intake: 1,200-1,500 kcal/day
Exercise Recommendations:
- 60 minutes of moderate to vigorous activity daily
- Weight training 3 times per week
- Set SMART goals (specific, measurable, achievable, realistic, timely)
- Implement self-monitoring techniques 1
A modest weight reduction of 5-10% can yield significant clinical improvements in metabolic parameters, menstrual regularity, and fertility outcomes. Health benefits can occur even without significant weight loss. 1, 2
Pharmacological Interventions
When lifestyle interventions alone are insufficient, medication may be necessary:
Insulin Sensitizers:
- Metformin: Start at 500 mg/day and gradually increase as tolerated
- Improves insulin sensitivity and reduces hyperandrogenism 1
Hormonal Therapy:
- Combined oral contraceptives (COCs): First-line treatment for menstrual irregularities and acne
- Not contraindicated in patients with type 2 diabetes 1
Anti-androgens:
- Spironolactone: Consider for patients resistant to first-line treatments
- Topical treatments: Eflornithine cream for facial hirsutism 1
Ovulation Induction (for fertility):
- Clomiphene citrate: Indicated for ovulatory dysfunction in women desiring pregnancy
- Most effective in PCOS patients with anovulation
- Should be started on or about the 5th day of the cycle
- Not recommended beyond a total of six cycles (including three ovulatory cycles) 3
- Contraindicated in patients with ovarian cysts (except PCOS), abnormal vaginal bleeding, or liver dysfunction 3
Monitoring and Screening
Regular monitoring is essential for PCOS management:
- Evaluate menstrual cycles every 3-6 months
- Screen for cardiovascular risk factors, including dyslipidemia
- Screen for anxiety and depression
- Monitor metabolic parameters annually
- Assess BMI and waist-hip ratio to evaluate central obesity 1
Important Considerations and Pitfalls
Ovarian Hyperstimulation Syndrome (OHSS):
- A serious potential complication of clomiphene citrate therapy
- Early warning signs: abdominal pain, distention, nausea, vomiting, diarrhea, weight gain
- Can progress rapidly within 24 hours to several days
- Use the lowest effective dose of clomiphene citrate to minimize risk
- PCOS patients may be unusually sensitive to clomiphene citrate 3
Visual Disturbances with Clomiphene:
- Visual blurring, scotomata, and other visual symptoms have been reported
- Discontinue treatment and seek prompt ophthalmological evaluation if visual symptoms occur 3
Adherence Challenges:
Long-term Risks:
By following this comprehensive approach to PCOS management, focusing first on lifestyle modifications and adding pharmacological interventions when necessary, patients can experience significant improvements in both short-term symptoms and long-term health outcomes.
