Polycystic ovary syndrome (PCOS) is often viewed mainly as a fertility or metabolic issue, but new research suggests the condition may carry a much deeper long-term health risk. In one of the largest studies of its kind, researchers found that women with PCOS faced a significantly higher risk of developing heart disease — including women who were considered normal weight and did not have Type 2 diabetes.
The study followed more than 127,000 women with PCOS across Denmark, Finland and Sweden over an average of 10 years. Researchers found that women with the condition had a 32% greater risk of heart disease overall.
Surprisingly, women with PCOS who maintained a normal weight still showed about a 40% increased risk, suggesting that the condition itself — not just obesity or diabetes — may directly affect cardiovascular health. Researchers pointed to hormone imbalances, particularly elevated testosterone levels, as one possible driver behind blood vessel dysfunction and rising blood pressure.
The findings add to growing concerns that PCOS may be more complex than previously believed. Researchers say the condition may involve multiple long-term disease patterns extending far beyond reproductive health alone. As awareness grows, the study highlights the importance of early monitoring and a more individualized approach to women’s health — especially for those who may appear healthy on the surface but still carry hidden cardiovascular risks.
