In a significant shift for women’s health, polycystic ovary syndrome (PCOS) has been renamed polyendocrine metabolic ovarian syndrome (PMOS), prompting calls for the NHS to swiftly update its online resources. This change comes after a collaborative effort spanning 14 years, involving medical professionals, advocacy groups, and individuals affected by the condition. Yet, as it stands, the NHS website has yet to reflect this important update, raising concerns about accessibility and clarity for patients navigating their healthcare options.
A Name Change Years in the Making
The new designation for PCOS, which is estimated to impact around one in eight women, aims to provide a more comprehensive understanding of the condition’s complexities. Neelam Heera-Shergill, the CEO of the charity Cysters, expressed her enthusiasm for the change but emphasised the necessity for immediate action.
“As an organisation deeply rooted in reproductive and health justice, we welcome discussions that better encapsulate the realities faced by those living with PMOS,” she stated. “However, any name change must transcend mere symbolism. Communities deserve clear, accessible, and timely information so that they are not left confused or struggling to obtain the support they need.”
Heera-Shergill highlighted that the lack of updated resources could disproportionately affect individuals from marginalised backgrounds, who often face additional barriers in accessing healthcare.
Transitioning to PMOS: Challenges Ahead
Despite the positive reception of the name change, the announcement comes with a three-year transition period during which both healthcare professionals and patients will need to adapt. Caroline Andrews, a trustee of the charity Verity, acknowledged the complexities involved.

“The NHS is undergoing significant changes, particularly with a new health secretary in place following Wes Streeting’s resignation,” she remarked. “Additionally, the renewed Women’s Health Strategy for England is being launched, and the National Institute for Health and Care Excellence (NICE) is set to release its first standalone guidelines for PMOS later this year. We understand that the NHS needs time to manage these transitions effectively.”
Andrews pointed out that careful and thoughtful implementation is crucial to ensure that the healthcare system can accommodate these changes while maintaining the quality of care.
Experts Weigh In on the Name Change
Prof Channa Jayasena, a reproductive endocrinology expert at Imperial College London, welcomed the updated terminology, viewing it as a vital step towards enhancing both understanding and treatment of the condition.
“This initiative is a tremendous advancement in acknowledging the seriousness of PMOS,” he said. However, he also cautioned that the transition to the new name will require time for widespread awareness and education among healthcare professionals.
Dr Sophie Williams from the University of Derby, who focuses on the intersection of PCOS and mental health, expressed concern regarding the potential confusion during the transition period.
“When the NHS website continues to reference polycystic ovary syndrome, it might lead the public to question the reliability of the information they receive,” she articulated. “The NHS website is often the first port of call for health advice, and it is essential that this resource remains trustworthy.”
To mitigate confusion, Williams suggested the possibility of maintaining dual webpages, one for each term, or including a notice about the name change on the existing page to guide patients effectively.
The NHS Responds
In light of these developments, a spokesperson for the NHS stated, “We routinely review and update content on the NHS website to ensure it reflects the latest clinical advice and will carefully consider these recommendations.” They assured that ongoing efforts to improve women’s healthcare would continue, focusing on increasing choice, reducing waiting times, and delivering more community-based care.

Why it Matters
The renaming of PCOS to PMOS represents more than just a change in terminology; it embodies a broader movement towards greater understanding and support for women’s health issues. As patients and advocates alike await updated information from the NHS, the urgency for clear and accessible resources has never been more critical. Ensuring that all individuals, particularly those from underserved backgrounds, can navigate their healthcare journey with confidence and clarity is essential for fostering trust and improving health outcomes in the long run.
