Summary

79% of adults with high blood pressure lack control.
Most uncontrolled cases aren't treated with medication.
Uncontrolled BP increases risks for heart disease and dementia.

A recent study indicates that a vast majority of American adults, approximately 79%, are not effectively managing their high blood pressure. This uncontrolled condition places millions at a heightened risk for severe health problems, such as heart disease and dementia. The findings, published on February 2, 2026, in the Journal of the American Medical Association, analyzed health data from over 3,200 individuals.

Further analysis revealed that 61% of those with uncontrolled blood pressure are not adhering to prescribed antihypertensive medications. Experts suggest that many of these individuals could achieve their blood pressure goals with medication and lifestyle adjustments, as their readings are only slightly above target.

The study debunked the notion that lack of healthcare access is the primary reason for uncontrolled blood pressure, noting that most affected individuals have health insurance and regular care access. Doctors emphasize that uncontrolled high blood pressure can lead to stroke, heart attacks, and organ damage if not properly managed.
