Nearly Half of Americans Have Hypertension, Yet Most Are Untreated or Uncontrolled
New NHANES data from 2021–2023 show 47% of Americans over 20 have hypertension, with 79% of those cases uncontrolled; among the uncontrolled, about 61% aren’t taking blood-pressure medications. Experts say many could reach the 130/80 target with medication and lifestyle changes, but awareness gaps and access issues hinder treatment, contributing to 664,470 deaths in 2023. The findings underscore the need for broader screening and better treatment uptake to improve cardiovascular health.
