In case you missed seeing this article. I’m resharing it.
A Kimberley pharmacist explains what the shift to PMOS means – and how individualized treatment is changing outcomes
For decades, a diagnosis that didn’t fit left millions of women cycling through appointments, second-guessing their symptoms and walking away without real answers.
Polycystic o***y syndrome – PCOS – was named for what early researchers observed in affected ovaries: clusters of small, fluid-filled sacs they mistook for cysts.
The label stuck for decades, even as the science moved on and clinicians came to understand the condition as something far broader – a complex hormonal and metabolic disorder with effects reaching well beyond the ovaries.
That changed in May 2026, when an international consensus published in The Lancet officially renamed the condition polyendocrine metabolic ovarian syndrome, or PMOS – the result of a 14-year global process involving 56 medical societies and more than 22,000 clinicians, researchers and patients across six continents.
For Michelle Gray, pharmacist, owner of Gray’s Compounding Pharmacy in Kimberley and certified master in hormone replacement therapy, the name change is long overdue.
“The old name sent people – and sometimes their doctors – looking in the wrong direction,” Michelle says. “PMOS is a hormonal and metabolic condition. When we understand it that way, we can actually start addressing the root causes.”
The condition doesn’t present the same way in everyone, which has contributed to years of missed and delayed diagnoses.
Slender women can have PMOS just as readily as those carrying extra weight – a fact that makes proper testing essential.
At Gray’s, the approach begins with comprehensive hormone testing before any recommendations are made.
Among the supplements Michelle works with, myo-inositol and D-chiro-inositol have some of the strongest evidence behind them.
In women with PMOS, the conversion between the two compounds is often impaired, disrupting insulin sensitivity, androgen levels and ovulation. Supplementing in the clinically studied 40:1 ratio helps restore that physiological balance.
Berberine is another option for women dealing with insulin resistance and blood sugar dysregulation – both common features of PMOS.
The plant-derived compound works through pathways similar to metformin, supporting more effective insulin use and healthier metabolic function.
For some women, chasteberry may also have a role, working through the pituitary gland to help reduce elevated prolactin that can interfere with cycle regularity – though its suitability depends on an individual’s full hormonal picture.
“Every woman’s hormonal profile is different,” Michelle says. “What works well for one person may not be right for another. That’s why we test first and make recommendations based on what we actually find.”
Anti-androgen support, dietary changes and targeted lifestyle guidance round out the toolkit – all calibrated to each patient’s individual results and goals.
For those eager to start the conversation, hormone consultations are available at Gray’s Pharmacy and can be booked online at grayspharmacy.ca/consultations.
