PCOS and Nutrition

While the causes of PCOS remain unclear, most experts believe insulin plays a major role in its development. The majority of PCOS patients have decreased insulin insensitivity, causing high levels of insulin or what is commonly known as insulin resistance. Approximately 50% of women affected by PCOS are overweight.

Risk Factors
Insulin resistance places an individual at increased risk for:
• Abnormal carbohydrate metabolism – raising the likelihood of developing type II diabetes
• Heart disease due to:
– Increased levels of LDL or “bad” cholesterol
– Decreased levels of HDL or “good” cholesterol
– Increased levels of triglycerides
– Increased blood pressure
• Significant weight gain and difficulty losing weight
• Low self-esteem

Lifestyle Modifications

Diet
Diet and exercise have been established as the first line of defense against PCOS. Studies show that a 5%-10% weight loss may substantially improve the metabolic and reproductive abnormalities associated with PCOS while lowering the risk of heart disease and type II diabetes. A registered dietitian (RD) can help customize a balanced diet, low in fat and moderate in carbohydrates, to help you achieve and maintain your weight loss goals. The RD will evaluate your current diet, lifestyle and risk factors and
establish a nutrition plan specific to your individual needs.
The following factors will be considered:
• Current height and weight
• Ideal body weight (IBW)
• Age, overall health and medical history
• Current medications or supplements taken
• Current eating patterns, food preferences and dietary customs

Exercise
Evidence clearly supports the importance of physical activity for women affected by PCOS; exercise may be just as important as diet in treating the disorder. Both aerobic exercise and strength conditioning can be effective in:
• Improving lipid levels
• Improving insulin insensitivity
• Lowering blood pressure
• Improving self-esteem
• Managing weight
• Aiding in prevention and treatment of chronic disease

An RD can help develop a customized exercise plan based on your preferences and lifestyle pattern.
