Polyendocrine Metabolic Ovarian Syndrome (PMOS) is a complex metabolic and hormonal condition that primarily affects women. The condition commonly becomes apparent during their reproductive years. It typically presents in ways such as irregular menstrual cycles, androgen excess, fertility issues, and metabolic dysfunction.
PMOS involves a complex interaction between increased insulin levels, insulin resistance, androgen production, ovarian function, and other factors, which can lead to irregular menstrual cycles and problems with fertility, blood glucose regulation, mood changes, and skin and hair issues.
PMOS is the updated name for what used to be referred to as PCOS, or Polycystic Ovarian Syndrome.
Why did the name change from PCOS to PMOS?
PCOS was changed to PMOS to reflect the broader metabolic and hormonal impact on the body than what was the previous consensus. The decision to rename the condition came from an international consensus process that involved 56 organizations and about 22,000 survey responses. The change was driven by years of research that showed PCOS was not just a disorder of the ovaries, but extended far beyond ovarian function. The condition affects multiple body systems, including hormone, metabolic, reproductive, dermatologic, and mental health systems, not just the ovaries.
The original name, PCOS, oversimplified the condition. It placed a disproportionate emphasis on the ovaries and “cysts”. However, the condition has more important and wide-reaching metabolic and systemic implications. You can have PMOS without ovarian “cysts”. Also, what is referred to as “cysts” are actually small, immature follicles rather than the typical type of ovarian cyst people tend to think of.
A PMOS diagnosis is based on a combination of symptoms, hormone levels, and sometimes ultrasound findings, not solely on the presence of cysts.
The name change from PCOS to PMOS reflects the broader hormonal and metabolic impact of the condition, which is consistent with the whole-person approach traditionally emphasized in naturopathic medicine. PCOS has always been a dysfunction of insulin regulation, androgen balance, ovarian function, and stress physiology. Now the name accurately reflects this dysfunction, putting more attention on the metabolic aspect of the condition than was previously.
The importance of recognizing the multi-system effects of PMOS is critical because it shifts the focus from a narrow diagnosis of ovarian dysfunction to a whole-body endocrine and metabolic disorder, something naturopathic doctors have long emphasized.
Does the name change from PCOS to PMOS mean the condition has changed?
No. The name change from PCOS to PMOS does not change the nature of the condition, especially from a naturopathic perspective. The diagnostic framework for PMOS in naturopathic medicine did not suddenly change.
Naturopathic medicine has long emphasized that PCOS is not just a reproductive disorder, but it isa condition that affects both hormone and metabolic functions. The bidirectional relationship between metabolic and hormone health in PMOS is a key concept that has always been highlighted by naturopathic medicine. For instance, insulin resistance drives hormonal imbalances, and hormonal imbalances can worsen metabolic health.
What does not change with the name change from PCOS to PMOS:
The condition is not a different disease.
Your existing PCOS diagnosis is not suddenly invalid.
You don’t need to start over with your medical history.
Existing treatments are not obsolete.
The terminology is changing, and healthcare systems will take time to adopt it.
Have Naturopathic treatments for PMOS changed along with the name?
No. Naturopaths are not treating PMOS any differently than when we referred to the condition as PCOS. The syndrome itself, its diagnosis, and its management remain the same in natural medicine.
From a naturopathic perspective, the change from PCOS to PMOS emphasizes the metabolic implications of the condition, which will now help other types of practitioners and patients to prioritize blood sugar stabilization, insulin management, and sugar intake. Naturopaths have the same treatment guidelines we’ve had all along.
What is the focus of a naturopathic approach for PMOS?
A naturopathic approach to PMOS takes a personal and holistic lens for each individual. We look at the whole person to identify which individual factors may be contributing to hormonal and metabolic imbalances and symptoms.
At Naturally Sue Wellness, our approach to treating PMOS aims to:
Regulate blood sugar levels and improve insulin resistance
Balance hormones
Ensure regular ovulation and menstrual cycles, and improve fertility
Strengthen lifestyle habits to optimize hormone balance and metabolic efficiency
We may include various strategies, including:
Therapeutic nutrition and dietary patterns
Insulin management and blood sugar stabilization
Nutritional supplementation
Herbal supplementation
Acupuncture
Physical activity & recovery
Strength training/muscle health
Stress reduction and meditation
Sleep hygiene
PMOS is complicated and complex, and everybody is different in what they need. A treatment approach that addresses your individual needs and root causes of symptoms is the best way to manage this condition and is key to long-term health.
The importance of the name change from PCOS to PMOS isn’t simply semantic—it reinforces what naturopaths have treated all along. Now other clinicians are paying attention to long-term metabolic health, not just reproductive symptoms.
PMOS isn’t just about periods, fertility, and cystic ovaries. In fact, ovarian function isn’t even a symptom for many individuals. PMOS is much more complex and is associated with increased cardiometabolic risks, like type 2 diabetes and insulin resistance. The name change from PCOS to PMOS simply reflects these broader health implications.
