Treatment Options for Polycystic Ovary Syndrome (PCOS) in Endocrinology

Lifestyle management is the first-line treatment for PCOS, with multicomponent interventions including diet, exercise, and behavioral strategies being central to improving metabolic, reproductive, and psychological outcomes. 1

First-Line Treatment: Lifestyle Modifications

Multicomponent Lifestyle Intervention

• Implement a comprehensive approach combining:
  • Dietary modifications
  • Regular physical activity
  • Behavioral strategies
  • Weight management (for those with excess weight)

Weight Management Goals

• Target 5-10% weight reduction in those with excess weight
• Energy deficit of 30% or 500-750 kcal/day (1,200-1,500 kcal/day)
• Consider individual energy requirements and activity levels 1

Physical Activity Recommendations

• Adults (18-64 years): Minimum 150 min/week moderate intensity or 75 min/week vigorous intensity exercise
• Include muscle-strengthening activities on 2 non-consecutive days/week
• Adolescents: At least 60 min/day moderate to vigorous activity 1

Dietary Approaches

• No specific diet is superior for PCOS
• Follow general healthy eating principles
• Options include low glycemic index foods, Mediterranean diet, or anti-inflammatory diets 2
• Avoid unduly restrictive or nutritionally unbalanced diets 1

Behavioral Strategies

• Implement SMART goal setting (specific, measurable, achievable, realistic, timely)
• Use self-monitoring techniques
• Include problem-solving, stimulus control, and relapse prevention strategies 1

Second-Line Pharmacological Treatments

For Menstrual Irregularities and Hyperandrogenism

• Hormonal contraceptives are first-line pharmacological treatment 3
  • Regulate menstrual cycles
  • Reduce androgen levels
  • Improve hirsutism and acne

For Insulin Resistance and Metabolic Abnormalities

• Metformin
  • Improves insulin sensitivity
  • Helps regulate menstrual cycles
  • Limited benefit for hirsutism or acne 3
  • Consider for women with metabolic risk factors or diabetes risk

For Infertility

• Clomiphene citrate is first-line therapy for ovulation induction 3, 4
  • Starting dose: 50 mg daily for 5 days
  • If no ovulation occurs, increase to 100 mg daily for 5 days
  • Do not exceed 100 mg/day for 5 days
  • Limit treatment to three ovulatory cycles if pregnancy not achieved
  • Monitor for visual symptoms and ovarian hyperstimulation syndrome 4

Special Considerations

Monitoring and Follow-up

• Regular assessment of weight, metabolic parameters, and reproductive function
• Monitor for psychological issues (anxiety, depression, body image concerns)
• Screen for cardiovascular risk factors and diabetes 1

Potential Complications to Monitor

• Ovarian hyperstimulation syndrome with clomiphene (abdominal pain, distention, nausea, vomiting) 4
• Visual disturbances with clomiphene (blurring, scotomata) 4
• Long-term metabolic and cardiovascular risks 5

Common Pitfalls to Avoid

1. Focusing only on fertility without addressing metabolic risks

   • PCOS requires long-term management beyond fertility concerns 5

2. Overlooking psychological impact

   • Address anxiety, depression, and body image concerns 1

3. Inadequate monitoring during pharmacological treatment

   • Clomiphene requires careful monitoring for ovarian enlargement and visual symptoms 4

4. Expecting immediate results

   • Lifestyle changes require time and consistency to show benefits 6

5. One-size-fits-all approach

   • Consider ethnic-specific BMI categories and cultural factors 1

The evidence strongly supports starting with lifestyle interventions for all women with PCOS, with pharmacological treatments added based on specific symptoms and treatment goals. Combination approaches (lifestyle plus appropriate medications) often yield the best outcomes for managing this complex endocrine disorder 6.
