PCOS in Australia: Symptoms, Diagnosis, and Treatment Options Online
%20Medium.jpeg)
Polycystic ovary syndrome is a hormonal condition that affects the ovaries and, in most cases, the body's broader metabolic function. Despite its name, not every woman with PCOS has visible cysts on her ovaries. The term "polycystic" refers to the appearance of multiple small follicles on the ovaries, which are partially developed eggs that have not been released during ovulation. These are visible on ultrasound but are not true cysts in the way most people understand the term.
At its core, PCOS involves an imbalance in reproductive hormones. Women with the condition typically have higher than normal levels of androgens, which are sometimes referred to as male hormones, though they are present in all women in smaller amounts. This hormonal imbalance disrupts the normal ovulatory cycle, which is why irregular or absent periods are one of the hallmark features. The condition also has a strong metabolic component. Research published by the Androgen Excess and PCOS Society has established that the majority of women with PCOS demonstrate some degree of insulin resistance, meaning the body's cells do not respond as efficiently to insulin, which can lead to higher circulating insulin levels and a cascade of metabolic effects.
The internationally recognised diagnostic framework for PCOS is the Rotterdam criteria, endorsed by the European Society of Human Reproduction and Embryology and the American Society for Reproductive Medicine, and adopted in the Monash University international PCOS guidelines. Under these criteria, a diagnosis requires the presence of at least two of the following three features: irregular or absent ovulation, which typically presents as irregular or absent periods; clinical or biochemical signs of hyperandrogenism, such as excess hair growth, acne, or elevated androgen levels on blood tests; and polycystic ovaries identified on ultrasound. Importantly, other conditions that can cause similar symptoms, such as thyroid disorders, congenital adrenal hyperplasia, and hyperprolactinaemia, must be excluded before a diagnosis of PCOS is made.
What makes PCOS particularly significant from a long-term health perspective is its metabolic dimension. The World Health Organization recognises PCOS as a condition that carries increased risk of type 2 diabetes, cardiovascular disease, and endometrial abnormalities over time. This does not mean that every woman with PCOS will develop these conditions. It means that early diagnosis and ongoing management are genuinely important, not only for symptom relief but for long-term health outcomes.
The symptoms of PCOS vary considerably between individuals, which is one of the primary reasons the condition is so frequently missed. Some women experience a cluster of obvious signs from adolescence onward. Others may have only one or two subtle indicators that do not immediately point to a hormonal condition. Understanding the full range of symptoms can help women recognise patterns that might otherwise be dismissed.
Irregular or absent periods are one of the most common presenting features. This may look like cycles that are consistently longer than 35 days, periods that arrive unpredictably, or months where menstruation does not occur at all. Some women with PCOS have always had irregular cycles and assume this is simply how their body works. While cycle variation exists on a spectrum, persistently irregular periods warrant a conversation with a GP, as they may indicate that ovulation is not occurring regularly.
Excess hair growth, known clinically as hirsutism, affects a significant proportion of women with PCOS. This typically appears on the face, particularly the chin, upper lip, and jawline, as well as the chest, abdomen, and back. It is driven by elevated androgen levels and is one of the symptoms that women most frequently report as affecting their self-esteem and daily quality of life. Conversely, some women with PCOS experience thinning hair on the scalp, following a pattern similar to androgenic hair loss, which can be equally distressing.
Persistent acne, particularly along the jawline and chin, is another androgen-driven symptom. Unlike typical adolescent acne, PCOS-related acne often continues well into a woman's twenties and thirties and may not respond to standard over-the-counter treatments. It is one of the symptoms that most commonly leads women to seek medical advice, though the underlying hormonal cause is not always identified at the first appointment.
Weight gain and difficulty losing weight are reported by many women with PCOS, particularly around the abdomen. This is closely linked to the insulin resistance that accompanies the condition. The relationship between weight and PCOS is complex and bidirectional: insulin resistance can make weight gain more likely, and excess weight can in turn worsen insulin resistance and hormonal imbalance. It is important to note that PCOS affects women across the full weight spectrum. Not all women with the condition carry excess weight, and a healthy weight does not exclude the possibility of PCOS.
Other symptoms include darkening of the skin in areas such as the neck, groin, and underarms, which is a clinical sign called acanthosis nigricans and is associated with insulin resistance. Mood changes, including increased anxiety and low mood, are also reported at higher rates among women with PCOS, a connection that is explored further below.
The key point is that not all women with PCOS will have all of these symptoms. The condition presents along a spectrum, and the combination and severity of symptoms varies from person to person. This variability is precisely why a thorough clinical assessment is essential for diagnosis.
There is no single test that confirms polycystic ovary syndrome. Diagnosis is a clinical process that involves a combination of history-taking, physical examination, blood tests, and sometimes imaging. A GP is typically the first point of contact and is well positioned to initiate this assessment.
The process usually begins with a detailed conversation about your menstrual history, including the regularity of your cycles, any changes over time, and when your periods first became irregular. Your GP will also ask about symptoms such as hair growth, acne, weight changes, and any difficulty conceiving if that is relevant to your situation. Family history matters too, as PCOS has a genetic component and tends to run in families. If a close relative has been diagnosed with PCOS, type 2 diabetes, or metabolic syndrome, this information helps your GP build a complete clinical picture.
Blood tests are a central part of the diagnostic workup. Your GP will typically order tests to measure androgen levels, including total testosterone and dehydroepiandrosterone sulphate (DHEA-S), which are the hormones most directly implicated in symptoms such as hirsutism and acne. The ratio of luteinising hormone (LH) to follicle-stimulating hormone (FSH) is often assessed, as an elevated LH-to-FSH ratio is a common finding in PCOS, though it is not required for diagnosis. Fasting insulin and glucose levels are important for identifying insulin resistance, which influences both treatment decisions and long-term health monitoring. Your GP will also order thyroid function tests and prolactin levels to rule out other conditions that can mimic the symptoms of PCOS. In some cases, additional tests such as a lipid profile and HbA1c may be included to assess broader metabolic health.
Pelvic ultrasound may be ordered to look for the characteristic appearance of polycystic ovaries, which involves twelve or more follicles measuring two to nine millimetres in diameter, or an increased ovarian volume. However, as the Monash PCOS guidelines note, ultrasound is not required for diagnosis if both irregular ovulation and hyperandrogenism are already present. In adolescents, ultrasound findings can be unreliable, and the guidelines recommend against using ultrasound as a primary diagnostic tool in this age group.
Diagnosis is ultimately made by your GP or specialist by applying the Rotterdam criteria, confirming the presence of at least two of the three features, and excluding other conditions that could explain the symptoms. Because PCOS is a diagnosis of exclusion, thoroughness matters. A GP who takes the time to investigate properly can save a woman years of uncertainty.
There is currently no cure for polycystic ovary syndrome, but the condition can be well managed with the right approach. Treatment is tailored to the individual based on which symptoms are most prominent, whether fertility is a current priority, and what the metabolic picture looks like. The goal is to manage symptoms, reduce long-term health risks, and support quality of life. All treatment decisions are made by your GP or specialist based on your individual clinical circumstances.
Lifestyle and Dietary Approaches
Lifestyle modification is considered a first-line intervention for PCOS across all major clinical guidelines, including the Monash international evidence-based guidelines. Regular physical activity, even modest increases in movement, has been shown to improve insulin sensitivity, support hormonal regulation, and reduce cardiovascular risk factors in women with PCOS. The evidence does not point to a single best type of exercise. What matters most is consistency and sustainability, whether that means walking, swimming, resistance training, or any activity that fits into your life.
Dietary approaches focus on improving insulin sensitivity and supporting a healthy weight where relevant. The RACGP and Jean Hailes for Women's Health recommend a balanced, whole-food approach that limits highly processed foods and refined carbohydrates, which can exacerbate insulin resistance. There is no single "PCOS diet" endorsed by clinical guidelines, and women should be cautious of restrictive approaches promoted online that lack an evidence base. A GP or accredited practising dietitian can help develop a sustainable eating plan tailored to your needs.
For women who are carrying excess weight, even a modest reduction of five to ten per cent of body weight has been associated with meaningful improvements in menstrual regularity, ovulation, androgen levels, and metabolic markers. This is a well-established finding in the PCOS literature and is one of the reasons lifestyle management is emphasised so strongly. However, it is equally important to acknowledge that weight management in the context of PCOS can be genuinely difficult due to the metabolic factors at play, and women should not be made to feel that their condition is a consequence of personal choices.
Hormonal Treatment
Hormonal treatment plays a central role in managing several of the most common PCOS symptoms. The oral contraceptive pill is frequently prescribed to regulate menstrual cycles in women who are not currently trying to conceive. By providing a regular hormonal cycle, it helps protect the endometrial lining from the thickening that can occur when ovulation is absent for prolonged periods, which is an important consideration for long-term reproductive health. The oral contraceptive pill also reduces circulating androgen levels, which can improve symptoms such as acne and hirsutism over time.
Anti-androgen medications may be prescribed in conjunction with hormonal contraception for women experiencing significant hirsutism or acne that has not responded to other treatments. These medications work by blocking the effects of androgens at the tissue level. They are not used during pregnancy and are typically prescribed alongside contraception for this reason. Your GP will discuss the benefits, potential side effects, and duration of treatment as part of a shared decision-making process.
Metabolic Management
For women with demonstrated insulin resistance, insulin-sensitising agents may be considered. These medications work by improving the body's response to insulin, which can in turn reduce circulating insulin levels, lower androgen production, and improve menstrual regularity. The decision to prescribe insulin-sensitising agents is a clinical one, based on the results of your blood tests and your overall metabolic profile. Your GP will monitor your response and adjust the approach as needed.
Fertility Support
PCOS is one of the most common causes of anovulatory infertility, meaning infertility related to the absence of regular ovulation. For women who are trying to conceive, the approach to treatment shifts. Ovulation induction, which involves the use of specific medications to stimulate the ovaries to release an egg, is typically the first-line fertility treatment for PCOS. This is managed by a GP with relevant experience or, more commonly, by a fertility specialist or reproductive endocrinologist. The process requires careful monitoring, including blood tests and ultrasound, to ensure the treatment is both safe and effective. Your GP can initiate the referral and coordinate care with the specialist team.
The relationship between PCOS and mental health is well established in the clinical literature, yet it remains one of the most under-addressed aspects of the condition. Research published by the Australian Institute of Health and Welfare and findings from the Monash PCOS guidelines indicate that women with polycystic ovary syndrome experience significantly higher rates of anxiety, depression, and psychological distress compared to the general population. These are not incidental associations. They reflect both the direct hormonal and metabolic effects of the condition and the cumulative emotional toll of living with symptoms that affect appearance, fertility, and daily functioning.
Body image concerns are particularly prevalent among women with PCOS. Symptoms such as hirsutism, acne, weight gain, and hair thinning affect areas of appearance that carry significant social weight, and the distress associated with these changes should not be underestimated. Research from Beyond Blue highlights that women managing visible chronic health symptoms are at elevated risk of social withdrawal, reduced self-esteem, and disordered eating patterns. For women with PCOS, the pressure to manage weight in the context of insulin resistance can create a particularly difficult relationship with food and exercise, one that deserves clinical attention rather than dismissal.
The emotional burden of a PCOS diagnosis itself can also be significant. For women who receive the diagnosis while trying to conceive, the news that their condition is a common cause of infertility can be deeply confronting. For younger women, learning that they have a lifelong condition with no cure can feel overwhelming, particularly if the diagnosis comes after years of unexplained symptoms and inconclusive investigations.
What matters is that mental health is not treated as a secondary concern. The Monash international PCOS guidelines explicitly recommend routine screening for anxiety and depression in all women diagnosed with the condition. Your GP can assess your mental health alongside your physical symptoms and, where appropriate, create a Mental Health Care Plan under Medicare, which provides access to subsidised sessions with a psychologist. This integrated approach, where the same clinician understands both the hormonal and the emotional dimensions of your experience, is how comprehensive PCOS care is meant to work.
If you have recognised yourself in any part of this guide, the most useful thing you can do is start a conversation with a GP who has the time and the context to listen properly. That is what Abby Health is built for.
Abby Health is an online-first clinic with more than 300 clinicians available seven days a week, 365 days a year. You can book a consultation from wherever you are in Australia, whether that is a capital city, a regional centre, or a remote community where getting in to see a GP can mean waiting weeks. The consultation takes place over a secure video call with a GP who has access to your health history, so you do not need to repeat your story every time you seek care.
For women concerned about PCOS, a consultation through Abby Health can serve as the starting point for a thorough assessment. Your GP can take a detailed history, order the appropriate blood tests and imaging, interpret the results in the context of your symptoms, and develop a management plan tailored to your situation. If hormonal treatment, insulin-sensitising agents, or a referral to a specialist such as an endocrinologist or fertility specialist is appropriate, your GP can initiate that pathway. If mental health support is needed, your GP can create a Mental Health Care Plan and refer you to a psychologist as part of a coordinated approach.
Continuity of care is central to managing a condition like PCOS, which requires ongoing monitoring and adjustment over time. Our rebooking data shows that three in four patients see the same clinician again, which means the GP who orders your initial blood tests is the same GP who reviews the results, adjusts your treatment, and follows your progress over the months and years ahead. That continuity is not a convenience. It is the foundation of effective chronic disease management.
Consultations are bulk billed for eligible patients, which means there may be no out-of-pocket cost for your appointment. Cost should not be the reason someone puts off investigating symptoms that have been affecting their life for months or years.
If you are ready to take that step, you can book a consultation through our Women's Health clinic today. You do not need a referral. You just need to show up. And if you are also experiencing symptoms such as pelvic pain or painful periods, our guide on endometriosis: when to see a doctor and how telehealth can help may also be a useful starting point.
