Polycystic ovarian syndrome is a complex hormonal condition involving many different aspects of our physical and mental health. This is why your specialist GP is the best person to diagnose and manage this disorder.
Women with PCOS can present with a range of symptoms and signs including:
Women with PCOS commonly have high levels of insulin, or male hormones known as ‘androgens’, or both. The cause of this is unclear, but insulin resistance is thought to be the key problem driving this syndrome, and this is why a diet low in carbohydrate is the cornerstone of managing PCOS.
In some women, PCOS runs in the family, whereas for others, the condition only occurs when they are overweight.
Diagnostic criteria for Rotterdam diagnosis of polycystic ovary syndrome.
Two of the following three criteria are required:
Other causes must be excluded such as congenital adrenal hyperplasia, androgen secreting tumours, Cushing syndrome, thyroid dysfunction and hyperprolactinaemia
There are a number of different definitions of PCOS, however the Rotterdam consensus is the most widely accepted in Australia, Europe and Asia and was the definition used for the Evidence-based guideline for the assessment and management of polycystic ovary syndrome developed by the PCOS Australian Alliance in 2011 (and updated in 2015). The information presented here is taken directly from the guideline.
1. Irregular menstrual cycles (Oligo/Anovulation)
In adolescent women (<18 years), after two years of irregular cycles (>35 or <21 days) following the onset the first period (menarche), polycystic ovary syndrome should be considered and appropriate assessment should be undertaken. As polycystic ovary syndrome is a diagnosis of exclusion, other causes of irregular cycles (such as thyroid dysfunction or hyperprolactinemia) need to be considered and excluded prior to the diagnosis of polycystic ovary syndrome.
High levels of androgens can cause effects seen in PCOS such as excessive hair growth, or abnormal patterns of masculine hair growth (hirsutism). In order to explore this, blood tests calculating the amount of testosterone in the blood can be performed. However people on the combined oral contraceptive pill will have a low level of testosterone, so it may be necessary to stop the pill for 3 months in order to check the testosterone levels. During this time other forms of contraception need to be looked at.
3. Polycystic ovaries
Polycystic ovaries are checked by ultrasound. Interestingly you do not need to have multiple cysts or follicles for the diagnosis of PCOS if there are irregular periods and signs of hyperandrogenism. Performing an ultrasound on younger adolescents can also give us a false impression of PCOS as there are many more follicles in younger women.
It is important that all the symptoms of PCOS are addressed and managed long term, to avoid associated health problems. PCOS is a long-term condition and long-term management is needed.
Lifestyle changes – such as eating a healthy diet low in carbohydrate and introducing regular physical activity into your weekly routine can have a positive effect on your health in so many ways. For women who have PCOS, a healthy lifestyle can lead to an improvement in symptoms, particularly if your new lifestyle helps you to lose weight.
You don’t even have to lose much weight to feel the benefit. Studies suggest that just 5 to 10 per cent weight loss can: restore normal hormone production – which can help regulate periods and improve fertility improve mood reduce symptoms such as:
It can also reduce your risk of developing type 2 diabetes and cardiovascular disease.
Medical treatments for PCOS
Medical treatments for PCOS treatments include:
If you have been suffering from irregular periods, have hair growth or thinning hair that concerns you, or weight loss is a particular issue (or a combination of the three) then it is important to exclude PCOS as a cause. As there are great ways to manage and live a healthy life, it is important to have clarity around the diagnosis.
