Treatment Options for Polycystic Ovary Syndrome (PCOS)
Lifestyle management is the first-line treatment for PCOS, with multicomponent interventions including diet, exercise, and behavioral strategies being most effective for improving hormonal outcomes, general health, and quality of life. 1
First-Line Treatment: Lifestyle Interventions
Dietary Approaches
- No specific diet 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
- Recommend at least 150 minutes/week of moderate intensity physical activity or 75 minutes/week of vigorous intensity activity 2
- Include muscle-strengthening activities on 2 non-consecutive days/week 2
- For greater health benefits, aim for at least 250 minutes/week of moderate intensity activities 2
- Both aerobic and resistance exercises have shown benefits in PCOS 2, 3
- 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 and self-monitoring
- Stimulus control and problem-solving
- Assertiveness training and slower eating
- Reinforcing changes and relapse prevention 1
- Address psychological factors such as anxiety, depression, body image concerns, and disordered eating 1
Medical Management Options
For Ovulatory Dysfunction/Infertility
- Clomiphene citrate is indicated for treatment of ovulatory dysfunction in women with PCOS desiring pregnancy 4
- Should be started on or about the 5th day of the cycle once ovulation has been established
- Long-term cyclic therapy is not recommended beyond a total of about six cycles
- Caution: May cause ovarian hyperstimulation syndrome (OHSS), which can progress rapidly and become serious 4
Special Considerations
- Ethnic-specific BMI and waist circumference categories need consideration when optimizing lifestyle and weight 1, 5
- Ethnic groups with PCOS who are at high cardiometabolic risk require greater attention for lifestyle intervention 1, 5
- Healthy lifestyle may contribute to health and quality of life benefits even without weight loss 1
- Regular monitoring of weight and waist circumference is recommended 2
Common Pitfalls and Caveats
- Patients with PCOS often describe significant difficulty losing weight; persistence with lifestyle modifications is essential 6
- Avoid focusing solely on weight loss as the goal; improvements in insulin sensitivity and hormonal balance can occur even with modest lifestyle changes 3
- Be aware of potential ovarian enlargement and cyst formation with clomiphene therapy, which usually regress spontaneously after discontinuing treatment 4
- Visual symptoms during clomiphene therapy require immediate discontinuation and ophthalmological evaluation 4
- Long-term management is necessary to reduce risks of metabolic-related diseases and endometrial cancer 7
The evidence strongly supports multicomponent lifestyle intervention as the cornerstone of PCOS management, with medical therapies like clomiphene added specifically for ovulatory dysfunction when pregnancy is desired.
