Effects of Exercise on Polycystic Ovary Syndrome

Few patients discuss polycystic ovary syndrome (PCOS) in orthopedic manual therapy, but one lady left a lasting impression. She was adopted and did not know her family’s medical history or her genetics. At 18, she had a baby as a result of rape. At 34, she was married and diagnosed with POCS. She struggled with infertility, anxiety, obesity, and hypertension. Although I saw her for cervicalgia, the exercise aspect of her therapy had potential to impact her overall well-being and possibly improve her PCOS symptoms.

Polycystic Ovary SyndromePericleous & Stephanides (2018) reviewed 10 studies that considered the effects of resistance training on PCOS symptoms. Some of these symptoms include the absence of or a significant decrease in ovulation and menstruation, which can lead to infertility; obesity, which in turn can affect cardiovascular health and increase the risk of diabetes, insulin resistance, and metabolic syndrome; and, mental health problems. Research has shown resistance training benefits include lowering body fat, improving insulin resistance and glucose metabolism, and increasing insulin sensitivity in type II diabetes. Although it has been documented that obesity and insulin resistance can exacerbate PCOS symptoms, resistance training is not a common recommendation in healthcare settings for patients with PCOS . Studies have shown diet and exercise are essential to improve cardiac and respiratory health and body makeup in patients with PCOS, as the combination improves the Follicle-stimulating hormone (FSH), sex hormone-binding globulin (SHBG), ovulation, testosterone levels, and weight loss. One systematic review found that weight loss can improve PCOS symptoms without consideration of diet; however, most other studies find intake of various macronutrients (protein, fat, carbohydrates) may lead to different results, and the effects of resistance training can only be optimized with appropriate dietary changes. These authors concluded caloric consumption and macronutrient habits must be considered in conjunction with resistance training to determine the greatest impact on improving PCOS symptoms.

Benham et al., (2018) also performed a recent systematic review to assess the role exercise can have on PCOS. Fourteen trials involving 617 females of reproductive age with PCOS evaluated the effect of exercise training on reproductive outcomes. The data published did not allow the authors to quantitatively assess the impact of exercise of reproductive in PCOS patients; however, their semi-quantitative analysis allowed them to propose exercise may improve regularity of menstruation, the rate of ovulation, and pregnancy rates in these women. Via meta-analysis, secondary outcomes of body measurement and metabolic parameters significantly improved after women with PCOS underwent exercise training; however, symptoms such as acne and hirsutism (excessive, abnormal body hair growth) were not changed with exercise. The authors concluded exercise does improve the metabolic health (ie, insulin resistance) in women with PCOS, but evidence is insufficient to measure the exact impact on the function of the reproductive system.

Increasing our knowledge about comorbidities such as PCOS, regardless of our practice setting, can help us provide better education to the patients we treat. Perhaps exercise compliance can increase when patients are told multiple long-term benefits, not just immediate symptom relief. More often than not, a patient’s 4-6 week interaction with us could motivate and promote healthy lifestyle changes.

Menopause, Weight Gain, and Pelvic Health

The new year is here and with it, lots of motivational posting about exercise and weight loss…but how is this desire for ‘new year, new you’ affecting peri-menopausal women with urinary dysfunction? It has been established that the lower urinary tract is sensitive to the effects of estrogen, sharing a common embryological origin with the female genital tract, the urogenital sinus. Urge urinary incontinence is more prevalent after the menopause, and the peak prevalence of stress incontinence occurs around the time of the menopause (Quinn et al 2009). Zhu et al looked at the risk factors for urinary incontinence in women and found that some of the main contributors include peri/post-menopausal status, constipation and central obesity (women's waist circumference, >/=80 cm) along with vaginal delivery/multiparity.

Could weight loss directly impact urinary incontinence in menopausal women? In a word – yes. ‘Weight reduction is an effective treatment for overweight and obese women with UI. Weight loss of 5% to 10% has an efficacy similar to that of other nonsurgical treatments and should be considered a first line therapy for incontinence’ (Subak et al 2005) But do these benefits last? Again – yes! ‘Weight loss intervention reduced the frequency of stress incontinence episodes through 12 months and improved patient satisfaction with changes in incontinence through 18 months. Improving weight loss maintenance may provide longer term benefits for urinary incontinence.’ (Wing et al 2010)

The other major health issues facing women at midlife include an increased risk for cardiovascular disease, Type 2 Diabetes and Bone Health problems – all of which are responsive to lifestyle interventions, particularly exercise and stress management. In their paper looking at lifestyle weight loss interventions, Franz et al found that ‘…a weight loss of >5% appears necessary for beneficial effects on HbA1c, lipids, and blood pressure. Achieving this level of weight loss requires intense interventions, including energy restriction, regular physical activity, and frequent contact with health professionals’. 5% weight loss is the same amount of weight loss necessary to provide significant benefits for urinary incontinence at midlife.

Successful weight management depends on nutritional intake, exercise and psychosocial considerations such as stress management, but for the menopausal woman, hormonal balance can also have an effect on not only bladder and bowel dysfunction but changing metabolic rates, thyroid issues and altered weight distribution patterns. As pelvic rehab therapists, we are all aware that pelvic health issues can be a barrier to exercise participation but sensitive awareness of the other particular challenges facing midlife women can make the difference in developing a beneficial therapeutic alliance and a journey back to optimal health.
