What health risks are associated with undiagnosed PCOS according to Canadian research?

Canadian research indicates PCOS increases risks of hypertension, kidney disease, depression, anxiety, and significantly, heart disease by 30-50% earlier.

What new developments are happening in PCOS research and care in Canada?

Alberta launched a clinical pathway for PCOS, and the University of Calgary's EMBRACE lab is developing patient tools with a PCOS Patient Advisory Council.

PCOS Hidden Danger: Canadian Study Reveals Health Risks

Polycystic Ovary Syndrome (PCOS), a hormonal imbalance affecting one in 10 Canadian women, is significantly underdiagnosed. This lack of recognition carries severe health consequences, with affected women facing a 20 to 40 percent greater risk of long-term health issues, including heart disease, hypertension, and mental health conditions.

The most critical concern is the heightened risk of cardiovascular disease, which is 30 to 50 percent more likely and occurs three to four years sooner in women with PCOS. This poses a significant threat, as cardiovascular disease is a leading cause of death globally. The financial and healthcare burden on affected women is substantial, often compounded by systemic failures in diagnosis and treatment.

Despite these challenges, progress is being made. An International PCOS Guideline published in 2023 promotes an individualized approach to treatment. In Canada, Alberta has launched a clinical pathway to improve PCOS recognition and care. Research labs like EMBRACE at the University of Calgary are actively working with patient advisory councils to develop tools and find solutions, aiming to improve screening, management, and outcomes for women with PCOS.
