Can what I eat and how I move help my Polycystic Ovary Syndrome?
What is PCOS?
Polycystic Ovary Syndrome (PCOS) affects around 10% of Australian women in their reproductive years. This is due to hormonal changes.
This ‘syndrome’ is linked to a range of health issues for affected women, trans or non-binary people. In the short term, those with PCOS may have reduced fertility and difficulty conceiving. In the longer-term obesity, diabetes and cardiovascular disease are more likely for people with PCOS.
Normally the ovaries produce large amounts of the female hormone oestrogen, lesser amounts of the male hormone testosterone, and the pregnancy hormone progesterone (which is only produced in greater amounts after ovulation and during pregnancy). In PCOS, testosterone levels are often mildly increased.
The causes of PCOS are unknown. In some cases, it seems to run in the family whereas for other women the condition only occurs when they are above their most healthy weight.
Women who have PCOS may experience:
- Irregular menstrual cycles – menstruation may be less frequent due to less frequent ovulation, and may be either heavier or lighter than average.
- Amenorrhoea – some women with PCOS do not menstruate, in some cases for many years.
- Infertility – related to less frequent, incomplete or absent ovulation.
- Increased body hair (hirsuitism)
- Obesity
- Acne
There may also be long-term health risks. Recent research suggests that PCOS is related to insulin resistance and the development of type 2 diabetes. Some women with PCOS develop type 2 diabetes, especially if they are overweight.
What is the latest research on PCOS and lifestyle changes?
Recently, new international evidence-based guidelines for the assessment and management of PCOS were released. This large body of work documented results from studies around the world and gives direction for the best treatment steps to take.
A take home message from these guidelines is the important role of ‘lifestyle management’ as the first line of therapy for PCOS and outline the clear benefits that result from a very achievable weight loss and increase in physical activity.
Do I have to get back to my ‘healthy’ BMI range for me to see improvements in my health?
No, the good news is that research shows that achieving a loss of just five to ten percent of your body weight, whatever weight you are at now, has significant effects for fertility and symptom management in women with PCOS. What might this look like? For most women, it is a loss of only 4 to 5 kg. Further health benefits come from greater losses, and are enhanced by increasing physical activity.
How active do I have to be to get health benefits?
A good goal is at least half an hour of moderate-intensity physical activity on most, preferably, all days. You do not have to do it all at once. Your exercise can be spread over the day, in ten minute blocks. Try three ten minute walks, or two fifteen-minute periods of activity.
What does moderate-intensity activity mean? Moderate-intensity means you are exercising at a comfortable pace. A good guideline is the “talk test” – you should be able to maintain a conversation easily without being short of breath.
What happens if I am already in my healthy BMI range?
Maintaining your weight in the healthy range can help prevent symptoms and longer term health risks for women with PCOS. Being a healthy weight is a balancing act: having a good knowledge of nutrition is important, but we also need to understand the reasons for why we eat, how we eat, what we eat, who we eat with and where we choose to eat. Believe it or not, there is a lot more to reaching and maintaining a comfortable weight than counting up kilojoules!
