Polyendocrine Metabolic Ovarian Syndrome (PMOS, formerly PCOS) is a common, long-term hormonal condition that affects around 8–13% of people of reproductive age, depending on how it’s diagnosed.
PMOS (PCOS) can feel confusing — especially because it doesn’t look the same for everyone. Symptoms vary. Experiences differ. And for many people, the path to diagnosis isn’t always straightforward.
In this article, we’ll explain what PMOS (PCOS) is, how it affects the body, the signs to look out for, and how it’s diagnosed and managed. Our goal is to provide clear, evidence-based information so you can better understand your symptoms and know what support options are available.
What Is PMOS (PCOS)?
Polyendocrine Metabolic Ovarian Syndrome (PMOS, formerly PCOS) is a common hormonal condition affecting people of reproductive age — and yes, it can start as early as the teenage years. It doesn’t just impact periods. PMOS (PCOS) can influence ovulation, fertility, skin, metabolism and long-term health.
At its core, PMOS (PCOS) is a complex hormonal and metabolic condition involving higher levels of androgens (male-type hormones), disrupted ovulation, and often insulin resistance. In simple terms? Hormones aren’t communicating as smoothly as they should.
And despite the name, you don’t actually need to have cysts on your ovaries to have PMOS (PCOS).
The good news: PMOS (PCOS) is highly manageable. With the right medical support, personalised lifestyle strategies, and, when appropriate, medication, most people can significantly improve symptoms and protect their long-term health.
What are the Signs and Symptoms of PMOS (PCOS)?
How to Tell If You Might Have PMOS (PCOS)
The signs and symptoms of PMOS (PCOS) vary from person to person, but they usually trace back to hormone imbalance and irregular ovulation. PMOS (PCOS) doesn’t just affect your periods — it can influence your skin, metabolism, fertility and overall wellbeing.
Common signs and symptoms include:
- Irregular periods: Periods may be infrequent, very far apart, unpredictable, or absent altogether. Some people experience heavier or prolonged bleeding when they do occur.
- Difficulty falling pregnant: PMOS (PCOS) can interfere with regular ovulation, which can make conception more challenging (though not impossible).
- Higher androgen symptoms: Elevated androgens (male-type hormones) can show up as acne, often around the jawline or chin, increased facial or body hair (hirsutism), or thinning hair on the scalp.
- Weight changes or difficulty losing weight: Insulin resistance is common in PMOS (PCOS) and can make weight changes more likely and weight loss more challenging. Importantly, PMOS (PCOS) occurs across all body sizes — and weight is not the cause of the condition.
- Polycystic ovaries on ultrasound: Some people will have enlarged ovaries with multiple small follicles (often called “polycystic ovaries”). Not everyone with PMOS (PCOS) has these, again, despite what the former name suggests.
Other associated symptoms of PMOS (PCOS) may include:
- Fatigue
- Mood changes or anxiety
- Darkened skin patches (often on the neck or underarms)
- Skin tags
- Increased risk of insulin resistance or type 2 diabetes
People with PMOS (PCOS) do have a higher long-term risk of certain health conditions, particularly when symptoms are not well managed. These can include:
- Type 2 diabetes
- Higher cholesterol levels
- Cardiovascular disease
- Endometrial hyperplasia (thickening of the uterine lining)
It’s important to keep this in perspective. Not everyone with PMOS (PCOS) will develop these conditions, and risk varies widely depending on individual factors, overall health and treatment approach.
With early diagnosis, regular monitoring and a personalised management plan, most people can significantly reduce their long-term risks.
If you’re experiencing symptoms or have concerns, a GP or specialist, like one of our caring team at Hazel, can assess your menstrual history, hormone levels and, where needed, imaging to make an accurate diagnosis and guide next steps.
How Is PMOS (PCOS) Diagnosed?
Tests, Scans, and What to Expect
PMOS (PCOS) is most commonly diagnosed during a detailed chat with your doctor or general practitioner. A PMOS (PCOS) diagnosis is usually based on a combination of symptoms, medical history, blood tests, and, in certain cases, an ultrasound.
During your consultation, your doctor will aim to rule out other conditions that could cause similar symptoms, such as hyperprolactinaemia, thyroid disorders, and non-classical congenital adrenal hyperplasia (CAH).
In Australia, doctors often use the Rotterdam criteria to diagnose PMOS (PCOS). This scale requires two of the three criteria points to be met.
- Irregular or Absent Ovulation: This will be either irregular, infrequent, or consistently missed periods.
- Signs of Elevated Androgens: Otherwise known as male hormones, which can manifest in symptoms such as acne, excess facial/body hair, or hair thinning. Results can also be found in blood tests.
- Polycystic Ovaries on Ultrasound: Not all women with PMOS (PCOS) will have this, but your ovaries will appear enlarged with multiple small follicles.
In general, a PMOS (PCOS) assessment in Australia will involve:
- A detailed medical history breakdown usually encompasses your period cycle, symptoms, weight changes, and fertility concerns.
- A physical examination.
- Blood tests to check your hormone levels, blood sugar, thyroid function, and rule out other conditions that can look similar to PMOS (PCOS).
- Pelvic ultrasounds, if your doctor says it’s required
How Is PMOS (PCOS) Treated?
Medical and Lifestyle Treatment Options
PMOS (PCOS) is usually managed with a combination of medical treatment and lifestyle support — and no two care plans look exactly the same.
Your approach should be tailored to your symptoms, your goals, and your stage of life. Whether you’re focused on regulating cycles, improving skin, protecting metabolic health, or trying to conceive, treatment is never one-size-fits-all.
Because PMOS (PCOS) is a long-term hormonal condition, management is less about a quick fix and more about steady, sustainable support. The aim is to improve day-to-day symptoms, protect long-term health, and help you feel more in control of your body — not constantly negotiating with it.
Medical Options for PMOS (PCOS) in Australia:
There are a variety of medical treatment options for PMOS (PCOS) in Australia. The specific medication that is prescribed by a doctor will directly relate to your specific symptoms.
These medical treatments can include:
Regulating Periods
What It Is Used For:
- Combined oral contraceptive pill to regulate cycles and reduce androgen symptoms.
- Cyclic progesterone to protect the uterine lining
Managing Insulin Resistance
What It Is Used For:
- Metformin is commonly prescribed to improve insulin sensitivity
- May assist with cycle regulation
Treating Excess Androgen Symptoms

Is There a Cure For PMOS (PCOS)?
There’s currently no cure for PMOS (PCOS) — but it is a highly manageable condition with the right support.
PMOS (PCOS) doesn’t simply “go away,” but many people live full, healthy lives with well-managed symptoms. With early diagnosis, personalised treatment and regular monitoring, long-term risks such as type 2 diabetes and cardiovascular disease can be significantly reduced.
Management focuses on supporting hormonal balance, protecting metabolic health and improving day-to-day symptoms over time.
Is it Hard to Live With PMOS (PCOS)?
It can be. But it doesn’t have to be.
PMOS (PCOS) doesn’t just affect your periods; it can influence energy, mood, metabolism, skin, fertility and self-confidence. That’s a lot for one condition to juggle. And because symptoms don’t always show up neatly or consistently, it can sometimes feel frustrating or unpredictable.
But here’s the important part: with the right care, most people are able to manage PMOS (PCOS) well.
For many, that means a combination of medical support, sustainable lifestyle strategies, and regular check-ins to monitor long-term health. It’s less about overhauling your entire life and more about making informed, steady adjustments that work for your body.
With appropriate support, people with PMOS (PCOS) can and do live full, healthy lives.
