Early Menopause: Health Risks & What to Know | Before 40

A novel study indicates that early or premature menopause – defined as occurring before age 40 – is linked to a significantly increased risk of heart disease, with disparities observed across racial groups.

Researchers found that women experiencing menopause early face a 41% higher risk of heart disease compared to those who enter menopause at a typical age, according to findings published March 19, 2026, in JAMA Cardiology. The increased risk is even more pronounced among Black women, who are three times more likely to experience menopause before the age of 40, and face a 39% increased risk.

The study underscores that early menopause is not simply a reproductive endpoint, but a potential health indicator requiring medical attention. “When menopause happens before age 40, women still have more than half of their lifetime ahead of them,” explained Dr. Priya Freaney, assistant professor of cardiology at Northwestern University Feinberg School of Medicine in Chicago. “Understanding the cumulative risks over their lifetime of developing heart disease associated with blockage is critical.”

Experts suggest that genetic factors, smoking, autoimmune diseases, and intensive medical treatments like chemotherapy can contribute to early menopause. The decline in estrogen associated with menopause is believed to play a key role in the increased cardiovascular risk.

Beyond heart disease, early menopause is likewise associated with an increased risk of osteoporosis. Women can lose up to 20% of their bone density within 5 to 7 years after menopause, increasing their susceptibility to fractures.

Medical professionals emphasize the importance of early diagnosis and consultation with physicians to explore treatment options. Hormone therapy may be considered in specific cases, alongside lifestyle modifications aimed at mitigating long-term health risks associated with early estrogen deficiency.
