After more than a decade of global consultation, polycystic ovary syndrome (PCOS) has been renamed. The condition, which affects as many as one in eight women, is now called polyendocrine metabolic ovarian syndrome (PMOS).
Why the Name Change?
Campaigners argued that the old name focused too narrowly on the ovaries, while the condition involves broader metabolic and endocrine issues. High levels of androgens cause symptoms such as excess hair, weight gain, and irregular periods. The new name aims to reflect the systemic nature of the disorder.
Impact on Patients
According to the Guardian’s science correspondent Nicola Davis, the renaming could reduce stigma and improve diagnosis. Rachel, a campaigner from the charity Verity, explains that the change brings fresh hope for millions of women, as it may lead to better understanding and treatment.
The global effort to rename PCOS was described as unprecedented, involving patients, clinicians, and researchers worldwide. The new name, PMOS, emphasizes the polyendocrine and metabolic aspects, potentially shifting focus toward holistic care.
