What Actually Changed, and What Did Not

The condition itself has not changed. Our bodies are the same. The symptoms are the same. Existing treatment plans, prescriptions, and referrals remain valid.

What changed is the name, and the name mattered enormously. The old name, polycystic ovary syndrome (PCOS), led millions of women to believe their ovaries were covered in dangerous, bursting cysts. They were not. Those dark spots on ultrasounds are undeveloped follicles, eggs that could not mature and be released properly because of hormonal and metabolic disruption throughout the whole body. Not cysts.

The new name, Polyendocrine Metabolic Ovarian Syndrome, tells a far more honest story:

• Poly-endocrine: Multiple hormones are involved, not just reproductive ones
• Metabolic: The condition deeply affects insulin, blood sugar, energy, and weight
• Ovarian: The ovaries are involved, but they are not the whole story

This consensus was built with responses from over 14,000 women and health professionals worldwide, using modified Delphi methods and nominal group technique workshops across all world regions. The new name was the nearly unanimous choice of clinicians, researchers, and patient advocates.

Why South Asian Women Have Been Carrying an Extra Burden?

Here is what nobody says loudly enough: South Asian women are disproportionately affected by PMOS, and disproportionately underdiagnosed.

Research consistently shows that women of South Asian descent experience higher rates of insulin resistance and more severe metabolic symptoms, often at lower body weights than Western diagnostic criteria were built to catch. A study published in the Journal of Obstetrics and Gynaecology found that polycystic ovaries were present in 52% of South Asian women studied in the UK, compared to 22% in predominantly Caucasian populations. South Asian women with PMOS also show higher insulin concentrations and lower insulin sensitivity, yet the old diagnostic criteria, built largely on Western bodies, frequently missed them.

Here is how PMOS specifically shows up in our communities, and why it so often goes unrecognised:

• Acanthosis nigricans (dark patches on the neck, underarms, or inner thighs) is a visible sign of insulin resistance that is often dismissed as a hygiene issue
• Hirsutism (excess facial and body hair) carries real cultural shame, especially when elders frame it as a beauty problem rather than a health signal
• Irregular periods that get normalised, with “some women are just like that” being the common response while years pass without a diagnosis
• Weight gain that does not respond to eating less because when insulin is dysregulated, standard dieting advice does not apply
• Fatigue, brain fog, and sugar crashes that get labelled as stress or laziness

Globally, an estimated 70% of people with PMOS remain undiagnosed. In South Asian communities, where cultural barriers around discussing women’s health, historic under-investment in women’s research, and ethnic-specific metabolic differences all converge, that number is likely even higher.

The Insulin Resistance Connection South Asian Women Need to Know About

Insulin resistance is the central metabolic feature of PMOS for most people who have it, and it is where the South Asian story gets particularly critical. South Asians are genetically predisposed to insulin resistance at lower BMIs. This means a South Asian woman with PMOS can have completely normal fasting glucose, a normal A1C, and a body weight her doctor considers healthy, and still have significant insulin dysregulation driving her symptoms. The standard tests often miss it. The standard cut-offs were not designed with her in mind.

Research from South India found that nearly half of women with PCOS met metabolic syndrome criteria despite having lower mean BMIs than their Western counterparts. This observation underscores the need for ethnicity-specific diagnostic approaches, since South Asian women are predisposed to insulin resistance even at weights that Western medicine considers safe.

This is exactly why the “M” in PMOS matters so much. It shifts attention from “do we see cysts?” to “how is the metabolism functioning?”, a question far more relevant for South Asian women who have been told for years that their labs look fine.

On the treatment side, metformin has long been used to address the insulin piece. More recently, GLP-1 receptor agonists (the class of medications that includes semaglutide and tirzepatide) are showing significant promise in regulating menstrual cycles, reducing androgen levels, and improving the full metabolic picture, often within weeks of starting, and often before any meaningful weight loss.

What the New Name Means for How We Navigate Care?

The renaming of PMOS is not just semantics. It is expected to shift several things in how care is delivered and accessed:

• Medical education: Future doctors will be trained to assess insulin resistance, thyroid function, cardiovascular risk, and mental health impacts together, not just irregular periods and ultrasound findings
• Research funding: With “metabolic” front and centre, there is a stronger case for funding PMOS research across cardiology, endocrinology, and psychiatry, not only gynecology
• Clinical conversations: There is now clearer language to bring to appointments. Asking for a full polyendocrine metabolic workup is a more complete and harder-to-dismiss framing than asking about ovarian cysts
• Policy and guidelines: The formal international guideline update is expected in 2028, with integration into disease classification systems and electronic health records globally

“My Ovaries Look Normal.” And Other Things That Kept Us Undiagnosed

One of the most common stories we hear at Sukoon: someone comes in with every classic PMOS symptom, jawline acne, irregular cycles, hair thinning, stubborn weight, fatigue after eating carbs, and they have been told repeatedly that because their ultrasound did not show “classic polycystic ovaries,” they do not have PCOS. The old name enabled that dismissal. The new one makes it harder to justify.

PMOS is diagnosed based on two of the following three Rotterdam criteria:

• Irregular or absent periods
• Signs of elevated androgens, either visible (acne, hirsutism) or confirmed through blood levels of testosterone
• Polycystic-appearing ovaries on ultrasound

Two of three is enough for diagnosis. The ovarian finding is not required. A woman with irregular periods and high testosterone who has “normal-looking” ovaries on ultrasound still qualifies for a PMOS diagnosis. Many South Asian women with the most metabolically severe presentations have been missed precisely because their imaging looked borderline. If this has been the experience, it was not imagined.

Eating with PMOS as a South Asian Woman in Canada

This is where most PMOS nutrition content gets it completely wrong for our community. The standard advice, cut carbs, avoid rice, swap roti for something else, is:

• Culturally disconnected from how South Asian families actually eat
• Unnecessarily extreme for most people with PMOS
• Missing the actual nutritional goal entirely

The goal is not to eliminate South Asian foods. The goal is to eat in a way that keeps insulin stable. Those are very different things, and it matters that we separate them.

What actually helps, without dismantling an entire food culture:

• Pair carbs with protein and fat: Dal with roti is not the problem. Roti alone is the problem. The fibre and protein in dal meaningfully slow the glucose response
• Do not skip meals: Irregular eating patterns worsen insulin dysregulation, which is the opposite of what someone with PMOS needs
• Prioritise sleep: Seven to eight hours of quality sleep is metabolic medicine. It is not optional when managing a condition rooted in hormonal dysregulation
• Add strength training: Muscle tissue is one of the most powerful sites of glucose uptake. Building it helps insulin sensitivity more than cardio alone for most people with PMOS
• Manage chronic stress: Cortisol directly worsens insulin resistance. For South Asian women carrying cultural pressure, immigration stress, and generational expectations, this piece is not a minor footnote

This is exactly the kind of support Sukoon Cares offers: culturally grounded, evidence-based, realistic for the life we are all actually living. Our registered dietitians understand South Asian eating patterns and will not ask anyone to stop eating the foods their family makes. We work with those foods, not against them.

What to Ask a Doctor Right Now?

If there is an existing PCOS diagnosis, or a strong suspicion of PMOS, here is a practical starting point for the next appointment. Ask for a full metabolic workup, not just a pelvic ultrasound. This should include:

• Fasting insulin (not just fasting glucose, which can look normal even with significant insulin resistance)
• HbA1c (three-month blood sugar average)
• Lipid panel (cholesterol and triglycerides)
• TSH (thyroid function, which is closely intertwined with PMOS symptoms)
• Free and total testosterone (the androgen piece)
• LH and FSH (hormonal signalling from the brain to the ovaries)
• Vitamin D (deficiency is closely linked to insulin resistance and is extremely common in Canada)
• AMH (anti-Mullerian hormone, particularly relevant for fertility planning)

If a doctor says labs are “fine” while multiple PMOS symptoms are present, it is worth pushing back. Ask specifically about fasting insulin and post-meal glucose response. A normal A1C does not rule out insulin resistance in the context of PMOS, especially for South Asian women.

Frequently Asked Questions About PMOS

Is PMOS more serious than PCOS?

PMOS is not a new, more serious condition. It is the same condition previously called PCOS, renamed to better reflect what it actually is: a multi-system hormonal and metabolic disorder. The new name sounds more complex because the condition always was more complex than the old name suggested. Nothing about any individual’s health picture has changed overnight.

Do medical records need to be updated?

No immediate action is needed. The 2028 international guideline update will formally integrate the new name into clinical systems globally. In the meantime, both PCOS and PMOS will be used interchangeably. Existing diagnoses, prescriptions, and referrals remain completely valid.

Will insurance cover PMOS treatment differently?

Not immediately. But the broader framing of PMOS as a metabolic condition, rather than a purely gynecological one, is expected to support coverage for a wider range of interventions over time, including metabolic medications. It is worth watching as guidelines update.

Can someone with PMOS still get pregnant?

Yes. Research shows that women with PMOS who want to conceive do so without IVF or fertility intervention. For those who need support, ovulation induction with medications like letrozole is highly effective. The key is connecting with a provider early, before actively trying to conceive, so insulin resistance and cycle regularity can be addressed upfront.

Is PMOS the same as PCOD?

PCOD (Polycystic Ovarian Disease) is an older, looser term still widely used in South Asian medical communities, particularly in India and Pakistan. It typically refers to ovaries that appear polycystic on ultrasound, without necessarily including the full hormonal and metabolic picture. PMOS is the complete, clinically recognised diagnosis that captures the whole body system. They overlap significantly but are not identical, and PMOS is now the accurate, internationally endorsed framing. Our team at Sukoon often sees this terminology confusion firsthand, and we are here to help navigate it.

How is PMOS diagnosed in Canada?

Diagnosis follows the Rotterdam criteria: two of three features (irregular periods, elevated androgens, polycystic ovarian appearance on ultrasound). A full workup should include fasting insulin, thyroid function, testosterone levels, and a pelvic ultrasound. Family physicians can initiate this; endocrinologists and registered dietitians can support ongoing management. Registered dietitian services at Sukoon Cares are often covered by extended health insurance plans in Canada.

The Answer Was Never Just About Our Ovaries

For every South Asian woman who was told her irregular periods were just stress, her

acne was just diet, her weight gain was just discipline: this rename is a small but real acknowledgment that the medical system was working with an incomplete picture.

The condition was always metabolic. It was always hormonal. It was always more than ovaries.

At Sukoon Cares, we work with South Asian women navigating exactly this intersection of identity, body, and health. Whether someone has a brand-new PMOS diagnosis, or has been managing this for years without the right support, our team is here to help build a plan that actually fits real life, including the food, the schedule, and the culture.
