    Unique Challenges forWomen with PCOS

    Yo-yo dieters

    Hypoglycemia common

    Hormonal aberrations

    Dermatological concerns

    Higher prevalence of eating disorders

    Impaired levels of ghrelin & leptin

    Increased anxiety, depression, bipolar, suicide

    What is the best dietcomposition ?

    Low-Fat Diets

    exaggerate postprandial glycemia

    increase TG, decrease HDLconcentrations

    promote higher consumption of refinedcarbohydrates

    Low vs. High Protein Diets

    28 overweight or obese PCOS women

    High protein (40% CHO, 30% Pro, 30% Fat) vs.Low Protein (55% CHO, 15% PRO, 30% Fat)

    Both diets 1400 calories for 3 months

    Weekly nutrition classes; exercise 3x/wk

    Results: No significant difference was found!

    Both groups lost weight, improved insulin,testosterone, menstrual function and other labs.

    Very Low-Calorie Diets

    114 obese women with PCOS

    500 calories/day for 4 weeks

    1,000 calories/day for 7 months

    Results: 54% lost > 5% of body weight,11.8% remained at pretreatment weight;both groups showed improvements intestosterone levels.

    What is the best dietcomposition ???

    For Reducing Insulin & Weight:

    Lower intake of carbohydrates

    Almost all whole grain, high fiber Avoidance of sweetened beverages

    Spread evenly throughout the day

    Eat frequently (every 3-5 hours)

    Protein matching at all meals and snacks

    Rich intake omega-3s

    For Heart Health

    Daily fat intake 35-45% of total daily calories

    No more than 7% saturated fat. Transfatsshould be eliminated

    Up to 20% of daily calories frommonounsaturated fatty acids, and up to 10%polyunsaturated fatty acids

    Consume fatty fish 2x/week

    Fish oil supplement

    Plant sterols

    Red wine

    Protein

    Lean, protein-rich foods with all meals andsnacks

    Experimenting for optimal foodcombinations

    Benefits of Protein

    Delays postprandial response

    Decreases hunger

    Increases satiety Decreases ghrelin

    Increases Thermic Effect of Food

    Preserves LBM

    Protein Intake & Fertility

    Nurses Health Study-18,000 nurses Highest-protein group had 41% more ovulatory

    infertility.

    Women with the highest intake of animal proteinhad 39% more ovulatory infertility than thosewith the lowest.

    Those who consumed the most plant-basedproteins had the lowest amount of infertility. exceptions were for eggs, dairy, and fish which were

    found to increase fertility.

    Supplements WithInsulin-Sensitizing Properties

    D - chiro inositol

    Chromium

    Cinnamon

    N-acetyl cysteine

    Alpha lipoic acid

    Magnesium

    Vitamin D3 Omega-3 fatty acids

    Role of Exercise

    3-month exercise program vs. hypocaloric diet

    19 sedentary women with PCOS

    SET: 25% improvement of insulin sensitivity

    without weight loss.

    improved fertility and menstrual cyclicity thanthose who followed a hypocaloric diet.

    SET group also had greater improvements inwaist circumference and insulin resistance

    despite only a smaller reduction in weight.

    Barriers to Physical Activity

    Size

    Muscular shape

    Its exercise!

    The Role of The Dietitian inTreating PCOS

    Empathetic, supportive, encouraging approach

    Provide education on PCOS and insulinresistance

    Education on healthy diet and exercise

    Encourage a healthy approach to eating andexercise rather than focusing on weight loss

    Assess symptom severity (including eatingdisorder behaviors)

    Assess medication compliance

    The Importance of NutritionCounseling for PCOS

    In a study on the effects of exercise andnutritional counseling in women withPCOS, Bruner et al (2006) found thatnutritional counseling, with or withoutexercise, decreased insulin levels andimproved both metabolic and reproductiveabnormalities associated with PCOS.

    The Nutrition Assessment

    Screen any woman for PCOS Provide appropriate referral information

    Screen for distorted eating

    Review lab results Assess diet

    Educate patient and parents about PCOS Insulin resistance Connection to symptoms Long-term risks Role of diet and exercise

    Assess readiness for change

    Tell me what your periods are like. Are they heavy,irregular, absent, etc.?

    What types of foods do you crave and when do you

    crave them? Do you ever feel lightheaded, dizzy, nauseous, orirritability that gets better when you eat?

    Have you ever been told by your physician or healthcareprovider that you have any abnormal lab values?

    Can you tell me about any excessive body hair thatyouve dealt with?

    Do you have dry/rough elbows, skin tags, or any darkpatches that look dirty on your body?

    Does anyone in your family have polycystic ovarysyndrome?

    Questions to ask a patientsuspected of PCOS: Tools

    Food records

    Mindful eating exercises

    Food models and labels

    Handouts

    How food affects insulinlevels

    Food exchanges

    Managing hypoglycemia

    Scale vs. waistcircumference

    Lab results

    PCOS in Pregnancy

    Higher risk for:

    Gestational diabetes

    -GDM ~ 3.5% in general population

    -GDM in PCOS estimated to be 20-50%

    -Early OGTT

    Miscarriage

    Neonatal intensive care stays

    Other Concerns in Pregnancy

    Multiple babies

    Food fears

    Emotional Concerns

    Weight gain

    Body image issues

    PCOS & Pregnancy

    Should be considered a state of GDM:

    -Moderate intake of carbohydrates

    -Even distribution of carbohydrates-Protein matching

    Daily exercise, preferably after meals

    Patient education of risks

    Appropriate weight gain

    Metformin in Pregnancy

    Unique Concerns:PCOS & Lactation

    Insufficient milk

    production

    Failure of breast

    tissue to develop

    Insulin resistance

    Adherence due to

    size

    Overabundance of

    milk production

    Guidelines To Establish AdequateMilk Supply in PCOS:

    Pump after feedings for 10-15 minutes on

    each breast in the first 2 weeks of initiatingnursing

    Frequent feedings with full drainage

    Adequate diet and fluid intake

    Extra breast stimulation by frequentnursing or pumping sessions is crucial

    Resources prior to birth

    Safety: Metformin & Lactation

    61 nursing infants and 50 formula fed infants

    born to mothers with PCOS

    took an average of 2.55 grams of Metformin per

    day throughout pregnancy and lactation

    Infants followed birth-6 mo.

    Metformin had no adverse health risks in

    regards to growth or motor-social development.

    Glueck C et al. J Pediatr2006;148:628-32.

    PCOS in Adolescence

    Adolescence is the most vulnerable and

    influential stage of PCOS.

    It is in adolescence when symptoms of PCOS

    first start to present themselves.

    Changes can be made to diet and lifestyle thatcould prevent the worsening of symptoms later

    in life and prevent the onset of many health

    complications.

    Obstacles Affecting Treatment

    Proper diagnosis/ Lab profile

    Patient readiness

    Mental status Anxiety, Depression, Eating disorders

    Social involvement

    Family involvement

    Resistance to exercise

    In Summary

    PCOS is a very complex, under-treated andunder-recognized epidemic

    Early detection and treatment are key

    Diet plays an important role in the treatment of

    PCOS

    RDs can offer lifestyle counseling on weight loss

    and diet to improve insulin resistance to reducethe risk of chronic disease within the PCOSpopulation
