PCOS Is Now PMOS: Understanding the New Name, Symptoms, Diagnosis and Treatment

For many years, Polycystic Ovary Syndrome (PCOS) has been one of the most widely recognised hormonal conditions affecting women.

Women searching online for information about PCOS may now encounter a new term: Polyendocrine Metabolic Ovarian Syndrome (PMOS).

The move towards the term PMOS reflects a broader understanding of this complex condition. Rather than viewing PCOS as a problem affecting only the ovaries or fertility, modern medical care recognises that the condition can involve multiple interconnected areas of health, including hormones, ovulation, insulin sensitivity, metabolism, weight, cardiovascular risk, mental health and reproductive health.

For women who have previously been diagnosed with PCOS, the most important message is reassuring:

The change in terminology does not mean that you suddenly have a different medical condition.

The underlying condition and the symptoms you experience have not suddenly changed. Instead, the terminology is intended to better communicate the complex and whole-body nature of the condition.

At Crown St Medical Centre in Surry Hills, our GPs provide comprehensive women’s health care for women experiencing symptoms associated with PMOS and PCOS, including irregular periods, fertility concerns, acne, excessive hair growth, hair thinning, weight changes and metabolic health concerns.

Whether you live in Surry Hills, Darlinghurst, Paddington, Redfern, Waterloo, Woollahra or the surrounding inner Sydney suburbs, our doctors can help assess your symptoms, investigate possible hormonal and metabolic causes and develop an individualised management plan.

What Is PMOS?

PMOS stands for Polyendocrine Metabolic Ovarian Syndrome, a newer term being used to describe the condition traditionally known as PCOS, or polycystic ovary syndrome.

The condition is common and can affect approximately one in eight women worldwide, although estimates vary depending on the population studied and diagnostic criteria used.

PMOS can involve a combination of:

• Hormonal changes
• Irregular or absent ovulation
• Irregular menstrual cycles
• Increased androgen activity
• Insulin resistance
• Metabolic dysfunction
• Weight-related health concerns
• Fertility difficulties
• Acne
• Excess hair growth
• Scalp hair thinning
• Increased risk of prediabetes and type 2 diabetes
• Cardiovascular risk factors
• Mental health concerns

Not every woman with PMOS experiences all of these features.

The condition can look very different from one person to another.

One woman may primarily experience irregular periods and fertility problems. Another may have significant acne and unwanted hair growth. Someone else may have insulin resistance or metabolic abnormalities without being overweight.

This variation is one reason why PMOS requires personalised medical assessment rather than a “one-size-fits-all” approach.

Why Was PCOS Renamed PMOS?

The terminology surrounding PCOS has been debated for many years.

The traditional name, “polycystic ovary syndrome”, can create several misunderstandings.

Many Women With PCOS Do Not Have Ovarian Cysts

One of the most common misconceptions about PCOS is that a woman must have ovarian cysts to have the condition. This is not correct.

The ovaries seen on ultrasound in some women with PCOS may contain multiple small follicles rather than true ovarian cysts.

Furthermore, some women who meet diagnostic criteria for PCOS do not have polycystic-appearing ovaries on ultrasound.

Conversely, some women without PCOS may have ovaries with a polycystic appearance on imaging.

This means that an ultrasound alone cannot diagnose or exclude PCOS/PMOS.

The Name PCOS Can Overemphasise the Ovaries

The traditional name can also give the impression that the condition is primarily a disorder of the ovaries.

In reality, PMOS/PCOS is a complex endocrine condition involving interactions between reproductive hormones, androgen activity, insulin regulation and metabolism.

Women may also experience associated issues involving:

• Blood glucose regulation
• Insulin resistance
• Weight management
• Cholesterol
• Blood pressure
• Cardiovascular risk
• Mental health
• Sleep
• Fertility
• Endometrial health

The proposed PMOS terminology aims to communicate this broader perspective.

Metabolic Health Is an Important Part of PMOS

Insulin resistance and metabolic dysfunction are important considerations for many women with PMOS/PCOS.

Insulin resistance occurs when the body’s cells respond less effectively to insulin.

The body may compensate by producing more insulin.

Over time, this can contribute to:

• Prediabetes
• Type 2 diabetes
• Increased triglycerides
• Abnormal cholesterol
• Weight gain
• Difficulty losing weight
• Increased cardiovascular risk

However, it is important to remember that not every woman with PMOS is insulin resistant and not every woman with PMOS is overweight.

Women of all body sizes can have PMOS.

This is why good medical care should focus on the individual’s metabolic health rather than making assumptions based solely on weight or appearance.

What Does PMOS Stand For?

The proposed name highlights three broad aspects of the condition.

Polyendocrine

“Polyendocrine” reflects the involvement of multiple hormonal and endocrine pathways.

These may include interactions involving:

• Insulin
• Androgens
• Testosterone
• Oestrogen
• Progesterone
• LH
• FSH

The hormonal picture can be complex, and hormone levels can vary depending on age, menstrual cycle, medications and other health factors.

Metabolic

“Metabolic” highlights the importance of metabolic health.

Women with PMOS may have an increased risk of:

• Insulin resistance
• Prediabetes
• Type 2 diabetes
• Abnormal cholesterol
• High blood pressure
• Weight gain

This is one reason why modern PMOS care increasingly includes cardiovascular and metabolic screening.

Ovarian

The ovaries remain an important part of the condition.

PMOS/PCOS can affect:

• Ovulation
• Menstrual cycles
• Fertility
• Reproductive hormones

However, the ovaries are only one part of a much broader endocrine and metabolic condition.

PCOS vs PMOS: What Has Actually Changed?

The most important point is that the underlying condition has not suddenly changed.

The terminology and understanding of the condition are evolving.

Women who have previously been diagnosed with PCOS should not assume that their diagnosis is invalid or that they need to start their assessment again from scratch.

During the transition in terminology, patients are likely to continue seeing both PCOS and PMOS used in medical information and online searches.

This is particularly important because PCOS remains the term that many women know and use when searching for healthcare.

Traditional PCOS terminology	PMOS terminology
Focus often placed on ovaries	Broader whole-body perspective
Name may suggest ovarian cysts	Greater emphasis on endocrine and metabolic health
Often associated with fertility	Recognises reproductive and non-reproductive health
Metabolic risk may be overlooked	Greater emphasis on metabolic screening
Cardiovascular health may receive less attention	Cardiovascular risk is an important consideration
Mental health can be overlooked	Psychological wellbeing recognised as part of comprehensive care
Management may focus on symptoms	Greater focus on long-term, personalised health

The new terminology is intended to encourage a more comprehensive approach to care.

What Are the Symptoms of PMOS?

Symptoms can vary significantly.

Some women experience several symptoms, while others have only one or two.

Irregular Periods

One of the most common symptoms is an irregular menstrual cycle.

This may include:

• Infrequent periods
• Missed periods
• Unpredictable cycles
• Long gaps between periods
• Irregular ovulation

Some women may also experience prolonged or heavy bleeding.

It is important not to automatically assume that irregular periods are caused by PMOS. Other conditions, including thyroid disorders, elevated prolactin, pregnancy, perimenopause, significant stress and other hormonal conditions, may also cause menstrual changes.

Difficulty Conceiving

PMOS/PCOS can affect fertility because ovulation may occur less frequently or unpredictably.

This can make it more difficult to conceive.

However, a diagnosis of PMOS does not mean that a woman cannot become pregnant.

Many women with PMOS conceive naturally, while others may benefit from fertility treatment or ovulation-induction medication.

If you are trying to conceive, a GP can provide preconception advice and help determine whether further fertility assessment is appropriate.

Weight Changes

Some women with PMOS experience:

• Weight gain
• Increased abdominal fat
• Difficulty losing weight
• Changes in appetite

However, weight gain is not essential for a diagnosis.

Women with a lower, average or higher BMI can all develop PMOS/PCOS.

Acne

Hormonal acne can be associated with increased androgen activity.

It may affect:

• The jawline
• Chin
• Neck
• Chest
• Back

Persistent adult acne may warrant assessment, particularly when accompanied by irregular periods or increased facial hair.

Excess Hair Growth

Increased androgen activity may cause unwanted hair growth, particularly on the:

• Face
• Chin
• Upper lip
• Chest
• Abdomen

This is known medically as hirsutism.

Hair Thinning

Some women experience scalp hair thinning or female-pattern hair loss associated with androgen activity.

Fatigue

Fatigue is commonly reported by women with PMOS, although fatigue is not specific to the condition.

Other causes should be considered, including:

• Iron deficiency
• Thyroid disease
• Sleep problems
• Mental health conditions
• Diabetes
• Medication effects

Mental Health Symptoms

Women with PMOS/PCOS may experience increased rates of:

• Anxiety
• Depression
• Body image concerns
• Reduced self-esteem
• Psychological distress

Mental health should be considered an important part of comprehensive PMOS care.

How Is PMOS Diagnosed?

The diagnostic approach remains broadly based on the established diagnostic principles used for PCOS.

There is no single blood test or ultrasound that can diagnose PMOS.

Diagnosis involves looking at the overall clinical picture.

Your GP may consider:

Your Medical History

Your doctor may ask about:

• Menstrual cycles
• Age when symptoms began
• Fertility
• Weight changes
• Acne
• Excess hair growth
• Hair thinning
• Medications
• Family history
• Diabetes risk
• Cardiovascular risk

Hormonal Blood Tests

Depending on your symptoms, your GP may consider blood tests such as:

• Total testosterone
• Free testosterone or calculated free androgen index
• SHBG
• Other androgen testing when clinically indicated
• Thyroid function
• Prolactin

LH and FSH may sometimes be tested depending on the clinical situation, although they are not diagnostic tests for PMOS/PCOS on their own.

Your GP will determine which tests are appropriate based on your symptoms and medical history.

Metabolic Health Testing

Because metabolic health is an important component of PMOS/PCOS, your doctor may assess:

• Blood glucose
• HbA1c
• Lipid profile
• Diabetes risk

In some circumstances, an oral glucose tolerance test may be recommended.

This can be particularly important because women with PMOS/PCOS may have an increased risk of impaired glucose tolerance and type 2 diabetes.

Blood Pressure

Blood pressure should be assessed as part of cardiovascular risk management.

Women with PMOS/PCOS may have increased cardiometabolic risk, making regular monitoring important.

Pelvic Ultrasound

An ultrasound may be useful in some circumstances.

However, ultrasound is not always required to diagnose PCOS/PMOS.

A normal ultrasound does not automatically exclude the condition.

Likewise, polycystic-appearing ovaries do not automatically mean that a woman has PMOS/PCOS.

The diagnosis needs to be made in the context of the individual’s symptoms, clinical findings and appropriate exclusion of other causes.

Does the Diagnosis of PMOS Change the Treatment?

The core principles of treatment remain broadly similar to those used for PCOS.

However, the PMOS terminology encourages doctors and patients to think more broadly about long-term health.

Treatment should be based on:

• Your symptoms
• Your reproductive goals
• Your metabolic health
• Your cardiovascular risk
• Your mental wellbeing
• Your preferences
• Whether you are trying to conceive

Lifestyle Management for PMOS

Lifestyle management remains an important foundation of care.

This may involve:

Healthy Eating

There is no single “PMOS diet”.

A balanced eating pattern may emphasise:

• Vegetables
• Fruit
• Whole grains
• Legumes
• Lean protein
• Fish
• Nuts and seeds
• Healthy unsaturated fats

A Mediterranean-style dietary pattern can be a practical framework for many people.

The aim should be sustainable nutrition rather than extreme dieting.

Regular Physical Activity

Regular movement can support:

• Insulin sensitivity
• Cardiovascular health
• Fitness
• Mood
• Sleep
• Weight management

Exercise does not need to be complicated.

Depending on your preferences and physical health, activities might include:

• Walking
• Running
• Swimming
• Cycling
• Dancing
• Pilates
• Strength training

The most effective activity is often the one you enjoy and can maintain consistently.

Sleep

Poor sleep may contribute to:

• Fatigue
• Appetite changes
• Reduced insulin sensitivity
• Mood difficulties

If you have symptoms of sleep apnoea, such as loud snoring, witnessed pauses in breathing or excessive daytime sleepiness, discuss this with your GP.

Stress Management

Stress does not cause PMOS, but chronic stress can affect sleep, mood, eating patterns and overall wellbeing.

Your GP can help identify appropriate strategies and support if stress, anxiety or depression is affecting your health.

Weight Management and PMOS

Weight management can be an important component of care for women who are above their healthy weight, but it should always be approached sensitively.

The goal should not be to focus solely on the number on the scales.

A comprehensive plan may consider:

• Nutrition
• Physical activity
• Sleep
• Insulin resistance
• Metabolic health
• Medications
• Mental health
• Reproductive goals

Even modest improvements in weight and metabolic health can be beneficial for some women.

However, it is important to recognise that PMOS is not a condition that only affects women who are overweight.

Women who are lean can also experience insulin resistance, irregular periods, androgen excess and other features of PMOS.

At Crown St Medical Centre Surry Hills, our GPs can discuss personalised weight management strategies where appropriate.

Medications for PMOS

There is no single medication that treats every aspect of PMOS.

Treatment depends on your symptoms and health goals.

Combined Oral Contraceptive Pill

The combined oral contraceptive pill may be prescribed for appropriate patients to help:

• Regulate menstrual cycles
• Manage heavy or irregular bleeding
• Improve acne
• Reduce androgen-related symptoms

Suitability depends on individual medical history and cardiovascular risk factors.

Metformin

Metformin may be considered in some women, particularly where metabolic features or insulin resistance are relevant.

It may help improve insulin sensitivity and glucose regulation.

It is not suitable for everyone and should be prescribed based on individual circumstances.

Fertility Treatment

Women who are trying to conceive may benefit from:

• Preconception care
• Ovulation assessment
• Fertility investigations
• Ovulation-induction medication
• Fertility specialist referral

The appropriate approach depends on the individual’s circumstances.

Weight Management Treatments

For selected patients, evidence-based weight management medications may be considered as part of a broader treatment plan.

These medications are not appropriate for everyone and require individual medical assessment.

Women who are pregnant, planning pregnancy or breastfeeding may require specific advice regarding medication safety.

Why Early Diagnosis and Long-Term Monitoring Matter

PMOS/PCOS is a long-term condition.

Early assessment provides an opportunity to identify and manage potentially modifiable health risks.

Depending on the individual, these may include:

• Insulin resistance
• Prediabetes
• Type 2 diabetes
• High cholesterol
• High blood pressure
• Cardiovascular risk
• Endometrial abnormalities
• Fertility challenges
• Mental health concerns

The purpose of early assessment is not to make women anxious.

It is to give women information about their health and opportunities to take action early.

PMOS and Cardiovascular Health

One of the most important developments in the modern understanding of PMOS/PCOS is the recognition that cardiovascular health deserves attention.

Women with PMOS/PCOS may have a higher prevalence of cardiovascular risk factors, including:

• High blood pressure
• Abnormal cholesterol
• Insulin resistance
• Prediabetes
• Type 2 diabetes
• Excess weight

The 2023 international evidence-based guideline recommends cardiovascular risk assessment in women with PCOS, including a lipid profile at diagnosis and regular blood-pressure assessment.

This does not mean that every woman with PMOS will develop heart disease.

It does mean that cardiovascular prevention should form part of comprehensive care.

At Crown St Medical Centre, your GP can help assess your individual risk and discuss appropriate screening and prevention strategies.

PMOS, Fertility and Pregnancy

PMOS/PCOS can affect ovulation and therefore fertility.

However, a diagnosis does not mean that pregnancy is impossible.

Many women with PMOS conceive naturally, while others may require assistance.

If you are considering pregnancy, preconception care can be valuable.

Your GP may discuss:

• Folic acid
• Weight and metabolic health
• Medications
• Blood pressure
• Diabetes screening
• Lifestyle
• Fertility planning

Women with PMOS/PCOS may have an increased risk of certain pregnancy complications, including gestational diabetes and hypertensive disorders of pregnancy.

Good preconception and antenatal care can help identify and manage these risks.

When Should You See a GP About PMOS or PCOS?

Consider booking an appointment if you experience:

• Irregular or absent periods
• Difficulty becoming pregnant
• Persistent adult acne
• Excess facial or body hair
• Scalp hair thinning
• Unexplained weight changes
• Difficulty losing weight
• Concerns about insulin resistance
• A family history of diabetes
• A family history of PMOS/PCOS
• High blood pressure
• Abnormal cholesterol
• Concerns about your long-term cardiovascular health

Frequently Asked Questions About PMOS

Is PMOS the same as PCOS?

PMOS is a newer term being used to describe the condition traditionally known as PCOS. The underlying health condition has not suddenly changed. The terminology aims to better reflect its endocrine, metabolic and reproductive features.

Why was PCOS renamed PMOS?

The terminology is intended to address misconceptions that the condition is primarily about ovarian cysts. It also highlights the broader hormonal and metabolic aspects of the condition.

Can I have PMOS if I do not have ovarian cysts?

Yes. The presence of polycystic-appearing ovaries is not essential for diagnosis. Some women with PMOS/PCOS have normal-appearing ovaries on ultrasound.

Do I need an ultrasound to diagnose PMOS?

Not necessarily. Diagnosis is based on the overall clinical picture and appropriate exclusion of other causes. Ultrasound may be useful in selected circumstances but is not always required.

Can PMOS affect fertility?

Yes. Irregular ovulation can make conception more difficult for some women. However, many women with PMOS/PCOS conceive naturally or with appropriate fertility support.

Does PMOS cause weight gain?

PMOS/PCOS can be associated with weight gain and difficulty losing weight, but not every woman with PMOS is overweight. Women of all body sizes can have the condition.

Does PMOS increase the risk of diabetes?

Women with PMOS/PCOS have an increased risk of impaired glucose tolerance and type 2 diabetes, particularly when other risk factors are present. Appropriate glucose screening can help identify problems early.

Does PMOS increase heart disease risk?

PMOS/PCOS is associated with an increased prevalence of cardiovascular risk factors such as high blood pressure, abnormal cholesterol, insulin resistance and diabetes. This is why cardiovascular risk assessment is an important part of comprehensive long-term care.

Can PMOS be cured?

There is currently no single cure for PMOS/PCOS. However, symptoms and associated health risks can often be effectively managed with lifestyle measures, medication and appropriate medical care.

When should I see a doctor about PMOS?

Consider seeing your GP if you have irregular periods, fertility concerns, persistent acne, excess facial hair, hair thinning, unexplained weight changes or concerns about metabolic or hormonal health.
