PMOS (formerly PCOS): what it is, symptoms, causes and holistic treatment approach
The new name PMOS (formerly PCOS) finally reflects what many women have been experiencing all along.
Hormonal symptoms rarely exist on their own. Yet with PCOS, many women have long been told that the condition is mainly about ovarian cysts. In reality, many are struggling with symptoms like acne, irregular cycles, weight fluctuations, blood sugar imbalance, digestive issues, fatigue, inflammation, hair growth, or difficulty conceiving, even without visible cysts on their ovaries. This is exactly why the condition recently received a new name: PMOS, which stands for Polyendocrine Metabolic Ovarian Syndrome.
Many women searching for PCOS symptoms, PCOS gut health, or hormonal acne often find that these patterns are deeply connected.
As a holistic dietitian working with women with PCOS, I believe this shift represents something important. Because for many women, the previous name never fully reflected what was really happening inside the body. PMOS recognises that this condition is not only ovarian, but deeply connected to metabolism, insulin regulation, inflammation, hormones, stress psycholgy and overall health.
Many women searching for answers around PCOS symptoms, hormonal acne, irregular cycles or difficulty losing weight may actually be experiencing deeper metabolic and hormonal imbalances underneath.
In my work, I have never seen PCOS as an isolated hormonal condition, but rather as part of a wider pattern involving blood sugar regulation, gut health, inflammation, the nervous system, and the microbiome. I think it is positive that this broader perspective is now becoming more widely recognised.
In this article, you’ll discover:
why PCOS was renamed to PMOS
the key symptoms and underlying root causes of PMOS
the role of insulin resistance, gut health, and inflammation
why many women with PMOS do not have visible ovarian cysts
and how you can support your body through a more holistic, root-cause approach
Why PCOS was renamed to PMOS
The term PCOS (Polycystic Ovary Syndrome) has been criticised for years within the medical community because it often fails to describe the full condition accurately.
Many women diagnosed with PCOS:
do not actually have ovarian cysts
experience symptoms beyond the ovaries
primarily struggle with metabolic or hormonal symptoms
The new name, PMOS (Polyendocrine Metabolic Ovarian Syndrome), was introduced to better reflect the complexity of the condition and its broader impact on the body.
The term:
“polyendocrine” refers to multiple hormonal systems being involved
“metabolic” highlights the important role of insulin resistance and metabolism
“ovarian” still acknowledges the reproductive component
This shift also reflects growing scientific recognition that PCOS, now increasingly referred to as PMOS, is not simply a reproductive disorder, but a whole-body condition involving hormones, metabolism, inflammation, and often the gut microbiome as well.
Common PCOS symptoms in women (PMOS: common signs your body may be communicating)
PMOS symptoms can look very different from person to person. Some women mainly experience cycle irregularities, while others struggle more with skin issues, blood sugar imbalance, inflammation, or weight regulation.
PCOS (PMOS) hormonal and metabolic symptoms
Some of the most common symptoms include:
irregular or missing periods
disrupted or absent ovulation
acne or oily skin
increased facial or body hair growth
hair thinning or hair loss
weight gain or difficulty losing weight
blood sugar instability
fatigue and moments of low energy
cravings, especially for sugar or carbohydrates
Digestive and inflammatory symptoms in PCOS (PMOS)
What I often see in practice is that PMOS rarely affects hormones alone.
Many women also experience:
bloating
constipation or irregular bowel movements
food sensitivities
low-grade inflammation
fatigue after meals
microbiome imbalance
skin conditions such as acne or eczema
This is also why gut health often plays an important role in hormonal balance and PMOS. If you regularly experience digestive symptoms alongside hormonal symptoms, you may also find my article about digestive root causes helpful: ‘’The root causes of digestive issues (and what your body is trying to tell you, with holistic advice)’’.
Insulin resistance and PCOS (PMOS): one of the most important underlying drivers
One of the reasons behind the shift in name from PCOS to PMOS is the growing recognition that insulin resistance plays a central role in many cases of insulin resistance PCOS. Insulin is the hormone responsible for helping glucose move from the bloodstream into the cells.
When cells become less sensitive to insulin:
the body produces more insulin
blood sugar regulation becomes disrupted
inflammation often increases
androgen production may rise
Elevated insulin levels can directly stimulate the ovaries to produce more androgens, which may contribute to:
acne
excess hair growth
disrupted ovulation
irregular cycles
This is also why many women with PMOS experience symptoms even when they eat healthy or exercise regularly, as the underlying imbalance often needs a more specific approach to restore balance and harmony.
And because acne is one of the most common symptoms linked to increased androgen levels and insulin dysregulation in PMOS, you may be interested in my article about the connection between hormones, inflammation and acne:‘‘Why your acne won’t go away (and what you’re missing)’’.
PCOS (PMOS), inflammation and the gut microbiome: the connection explained
Emerging research increasingly shows that the gut microbiome plays an important role in hormonal and metabolic health.
Your gut microbiome influences:
inflammation levels
insulin sensitivity
estrogen metabolism
nutrient absorption
immune regulation
Research also suggests that women with PMOS often show altered gut microbial patterns compared to women without PMOS.
In practice, I often see that women with PMOS/PCOS also struggle with:
low microbial diversity
digestive symptoms
chronic stress
inflammation
blood sugar instability
This creates a cycle where the microbiome, metabolism, inflammation and hormones continuously influence one another. This is one of the reasons why purely symptom-focused approaches often do not lead to long-term improvement.
Why PCOS (PMOS) is not just a hormonal condition
What I see with my clients is that PCOS/PMOS is not only about the ovaries.
It is often connected to:
blood sugar regulation
chronic stress
nervous system dysregulation
gut microbiome imbalance
inflammation
sleep quality
suppressed emotions
perfectionism
lifestyle patterns
nutrient status
This is also why two women with the same diagnosis can experience completely different symptoms. For one woman, acne may be the dominant symptom. For another, it may be irregular cycles, fatigue, digestive issues, or fertility struggles.
Understanding your personal root causes is therefore essential.
Holistic support for PCOS (PMOS): supporting hormones, metabolism and gut health naturally
Instead of focusing only on suppressing symptoms, I always look at restoring communication and balance within the body.
Supporting blood sugar balance and insulin sensitivity in PCOS (PMOS)
Blood sugar regulation is one of the most important foundations in PMOS support.
Holistic support you can start today:
Eat balanced meals with protein, fibre, healthy fats and carbs
Avoid skipping meals or under eating
Include fibre-rich foods such as vegetables, legumes, oats, nuts and seeds
Prioritise protein at every meal, especially breakfast
Reduce ultra-processed foods and excess added sugars
Include cinnamon in meals or drinks for additional blood sugar support
Apple cider vinegar before meals can also help support more stable glucose responses
Some type of movement after your meals to support glucose regulation
Supporting the gut microbiome and reducing inflammation in PCOS (PMOS)
Supporting your gut microbiome positively influences hormonal balance, insulin sensitivity and inflammation.
Holistic support you can start today:
Eat a diverse range of plant foods
Include polyphenol-rich foods such as berries, pomegranate, green tea, herbs, beetroot, flax seeds and extra virgin olive oil
Include omega-3 rich foods such as fatty fish, walnuts, chia seeds and hemp seeds
Support digestion through mindful eating and chewing thoroughly
Reduce personal chronic inflammatory triggers where possible
Supporting the nervous system and stress regulation in PCOS (PMOS)
One of the most underestimated aspects of PMOS is the nervous system.
When the body experiences chronic stress:
cortisol levels may rise
insulin sensitivity may worsen
inflammation can increase
ovulation may become disrupted
Holistic support you can start today:
Prioritise sleep and recovery
Slow down your mornings
Practice breathing exercises before meals
Create moments of calm throughout the day
Choose movement that nourishes rather than exhausts your body. Yoga, pilates, strength training or walking are often more supportive than intense workouts.
PCOS (PMOS) and fertility: why hormones and metabolism matter together
PMOS can affect fertility because ovulation may become irregular or absent. Many women with PCOS also struggle with ovulation, which can make conception more difficult and is one of the main reasons why getting pregnant can feel challenging.
However, what is often overlooked is that fertility is closely connected to:
metabolism
inflammation
stress physiology
gut health
nutrient status
This is also why supporting your whole body often improves cycle health naturally. In practice, I regularly see that once blood sugar balance, inflammation and stress regulation improve, cycles often become more regular and conception may become possible again.
If you want to read more about this, you may also find my article “Why many of my clients get pregnant more easily: a holistic approach to women’s fertility”helpful.
Why a personalised approach to PCOS (PMOS) matters
PMOS is highly individual. Some women are primarily affected by insulin resistance. Others by inflammation, chronic stress, digestive dysfunction, or microbiome imbalance.
A one-size-fits-all approach often focuses mainly on symptom management rather than understanding what is driving your personal imbalance underneath.
This is why personalised guidance and testing can be valuable.
Looking at:
hormone patterns
microbiome balance
lifestyle factors
nervous system regulation
digestive function
inflammation markers
can help create a much more sustainable and personalised approach.
PMOS is not just a new name for PCOS: it reflects a new understanding of women’s health
For many women, the change from PCOS to PMOS feels validating. Because it acknowledges what they may have been experiencing for years that this condition affects far more than the ovaries alone.
Your hormones do not function separately from your metabolism, gut, nervous system or lifestyle.
Everything in the body is connected. This is exactly why a holistic approach matters.
Personalised and holistic support for PMOS (formerly PCOS)
PMOS is not just a hormonal diagnosis. It is often a message from the body that something deeper within your metabolism, hormones, gut health or nervous system needs support.
If you recognise yourself in these symptoms, it may be less about finding the perfect diet and more about understanding your unique root causes and nourishing your body.
As a holistic dietitian, I support women in identifying possible underlying drivers behind PMOS through personalised nutrition, lifestyle guidance, nervous system support and microbiome-focused testing.
If you would like support in understanding your body better and restoring balance and harmony in a more sustainable and holistic way, I would love to support you.
Consultations are online and worldwide available.
Looking forward to meeting you.
Love,
Nina
Frequently Asked Questions about PCOS (PMOS)
-
PCOS is often driven by a combination of insulin resistance, inflammation, hormonal imbalance, stress, and gut microbiome disruption. It is mostly not caused by one single factor, but rather a combination of metabolic and lifestyle-related influences.
-
Insulin resistance is common in PCOS/PMOS and can increase insulin levels in the body, which may stimulate the ovaries to produce more androgens. This can contribute to symptoms such as acne, irregular cycles, and difficulty ovulating.
-
A PCOS-supportive approach usually focuses on blood sugar balance, supporting gut health, hormonal balance and lowering inflammation. This includes protein-rich meals, healthy fats, fibre-rich foods, and reducing ultra-processed foods and sugar spikes.
-
Yes, many women with PCOS (PMOS) can conceive naturally. Supporting ovulation through blood sugar balance, stress regulation, gut health, and hormonal balance can significantly improve fertility outcomes.
-
Common signs include bloating, food sensitivities, acne, fatigue after meals, and irregular cycles. The gut microbiome plays an important role in hormone metabolism and inflammation regulation.
-
Yes. Many women see improvement in symptoms when focusing on root causes such as insulin resistance, stress, inflammation, sleep, and gut health rather than only treating symptoms. This is also what I see in practice when I help my clients.
