Treatment Options for Polycystic Ovary Syndrome (PCOS)
Multicomponent lifestyle intervention including diet, exercise, and behavioral strategies is the first-line management for PCOS, particularly for those with excess weight, to reduce weight, central obesity, and insulin resistance. 1
Lifestyle Management
Dietary Approaches
- No specific diet type has proven superior; focus should be on individual preferences while maintaining a healthy balanced diet 2
- For weight loss, aim for an energy deficit of 30% or 500-750 kcal/day (1,200-1,500 kcal/day) 2
- Avoid unduly restrictive or nutritionally unbalanced diets 2
- Achievable goals such as 5-10% weight loss in those with excess weight yield significant clinical improvements within 6 months 1
Physical Activity Recommendations
- At least 150 minutes/week of moderate intensity physical activity or 75 minutes/week of vigorous intensity activity for prevention of weight gain 2
- For modest weight loss, recommend at least 250 minutes/week of moderate intensity activities 2
- Include muscle-strengthening activities on 2 non-consecutive days/week 2
- Both aerobic and resistance exercises have shown benefits in PCOS 2
- Minimize sedentary, screen, or sitting time 2
Behavioral Strategies
- Implement SMART (specific, measurable, achievable, realistic, timely) goal setting and self-monitoring 1
- Include behavioral strategies such as goal-setting, self-monitoring, stimulus control, problem-solving, assertiveness training, slower eating, reinforcing changes, and relapse prevention 1
- Consider comprehensive behavioral or cognitive behavioral interventions to increase engagement and adherence 1
- Address psychological factors such as anxiety, depression, body image concerns, and disordered eating 1
Pharmacological Management
For Ovulatory Dysfunction
- Clomiphene citrate is indicated for the treatment of ovulatory dysfunction in women with PCOS desiring pregnancy 3
- Treatment should be properly timed in relation to ovulation 3
- Long-term cyclic therapy is not recommended beyond a total of about six cycles 3
- Patients should be carefully evaluated before treatment to exclude pregnancy, ovarian cysts (except in PCOS), abnormal vaginal bleeding, and liver dysfunction 3
For Metabolic Abnormalities
- Metformin may help improve insulin sensitivity and metabolic parameters in women with PCOS 4
- Orlistat may assist with weight loss and improve lipid and glucose metabolism 4
Special Considerations
Monitoring and Follow-up
- Regular monitoring of weight and waist circumference is recommended 2
- Ongoing assessment during weight loss and maintenance is important 1
Ethnic-Specific Considerations
- Ethnic-specific BMI and waist circumference categories need to be considered when optimizing lifestyle and weight 1, 5
- Ethnic groups with PCOS who are at high cardiometabolic risk require greater consideration for lifestyle intervention 1, 5
Benefits Beyond Weight Loss
- Healthy lifestyle may contribute to health and quality of life benefits even in the absence of weight loss 1, 6
- Lifestyle modifications not only improve biochemical, hormonal, and anthropometric parameters but also reduce long-term risks of metabolic and cardiovascular diseases 6
Common Pitfalls and Caveats
- Many women with PCOS describe significant difficulty losing weight; treatment options should be started early to avoid unnecessary delays 7
- Obesity exacerbates PCOS phenotype including infertility and reduces efficacy of fertility treatments 7
- Health professional interactions should be respectful, patient-centered, and considerate of individual preferences and cultural differences 1, 2
- Untreated PCOS can lead to long-term consequences including adverse pregnancy outcomes, increased risk of endometrial cancer, and type 2 diabetes mellitus 4
