Treatment Options for Polycystic Ovary Syndrome (PCOS)
Lifestyle modifications combined with appropriate pharmacological interventions should be the cornerstone of PCOS management, with specific approaches tailored based on the patient's reproductive goals and symptom presentation. 1
First-Line Treatment: Lifestyle Modifications
Lifestyle interventions are recommended for all patients with PCOS, with particular emphasis on those with excess weight:
Weight Management:
Dietary Approach:
- Focus on low glycemic index foods
- Incorporate anti-inflammatory diet patterns
- Ensure adequate magnesium and zinc intake
- Limit calories from fat to 25-30%
- Limit saturated fat to <7%
- Avoid trans fats 1
Physical Activity:
Behavioral Strategies:
Pharmacological Management Based on Treatment Goals
For Menstrual Irregularities and Hyperandrogenism:
Combined Oral Contraceptives (COCs):
- First-line treatment for menstrual irregularities and acne
- Not contraindicated in patients with type 2 diabetes 1
Anti-androgens:
- Consider spironolactone for patients resistant to first-line treatments
- Topical treatments like eflornithine cream can be used for facial hirsutism 1
For Women Planning Pregnancy:
- Ovulation Induction:
Clomiphene Citrate:
- First-line medication for ovulation induction
- Approximately 80% of PCOS patients ovulate with clomiphene, with half achieving pregnancy 1
- Important safety consideration: Monitor for visual symptoms (blurring, scotomata) which require immediate discontinuation 4
- Caution: Risk of Ovarian Hyperstimulation Syndrome (OHSS), particularly in PCOS patients who may be unusually sensitive to gonadotropin 4
Metformin:
If first-line treatment fails:
- Consider low-dose gonadotropin therapy to induce monofollicular development with lower risk of ovarian hyperstimulation 1
Monitoring and Evaluation
- Evaluate menstrual cycles every 3-6 months
- Monitor metabolic parameters annually
- Assess body mass index (BMI) and waist-hip ratio to evaluate central obesity
- Screen for:
Common Pitfalls and Caveats
Ovarian Hyperstimulation Risk: PCOS patients may be unusually sensitive to fertility medications. Start with the lowest recommended dose of clomiphene citrate and shortest treatment duration for the first course 4
Monitoring for OHSS: Early warning signs include abdominal pain/distention, nausea, vomiting, diarrhea, and weight gain. This condition can progress rapidly and become serious 4
Visual Side Effects with Clomiphene: Any visual symptoms during treatment require immediate discontinuation and ophthalmological evaluation 4
Adherence Challenges: Lifestyle interventions show clear benefits but retention and sustainability can be challenging, highlighting the need for behavioral support strategies 2, 3
Contraindications: Statins may improve lipid profiles and reduce systemic inflammation but are contraindicated in pregnancy 5
The evidence strongly supports a comprehensive approach to PCOS management, with lifestyle modifications as the foundation and appropriate pharmacological interventions based on the patient's specific needs and reproductive goals.
