The American Heart Association (AHA) and the American College of Cardiology (ACC) have released the first updated blood pressure guidelines since 2017, calling for earlier and more aggressive treatment of high blood pressure and recommending that people abstain from alcohol. These changes reflect growing evidence that stricter control of blood pressure reduces risks of heart disease, kidney disease, type 2 diabetes, stroke, and dementia.
Nearly half of U.S. adults have elevated blood pressure. The definition of blood pressure categories remains the same: normal is below 120/80 mm Hg, elevated is 120–129/80 mm Hg, and high is 130/80 mm Hg or higher. The key shift is that individuals with systolic blood pressure between 130 and 139 mm Hg will now be encouraged to adopt healthy lifestyle changes first. If these do not bring improvement within three to six months, medication will be recommended. In 2017, medications were generally advised only when systolic readings were above 140.
Lifestyle changes emphasized in the new guidelines include maintaining a healthy weight, adopting a heart-healthy diet such as the DASH diet, limiting salt, increasing potassium intake, managing stress, and getting at least 150 minutes of moderate physical activity per week. Resistance training is also encouraged. A major change concerns alcohol: past guidance allowed up to one drink per day for women and two for men, but the new guidelines highlight evidence linking alcohol to higher blood pressure and recommend abstinence as the ideal. For those who still choose to drink, limits remain below one daily for women and below two for men.
The updated guidelines also place greater emphasis on women’s health, particularly during pregnancy. High blood pressure in pregnancy can harm both the parent and baby, and it raises long-term risks of elevated blood pressure. Preventing hypertension in this group is therefore a new priority.
Sodium reduction is again strongly encouraged, with recommendations to keep daily intake under 2,300 mg and ideally near 1,500 mg. Substituting potassium-based salts is one strategy to achieve this. For people with overweight or obesity, losing at least 5% of body weight is recommended, while more severe cases may require medications or surgery.
Ultimately, the guidelines stress prevention through lifestyle changes. While they acknowledge that maintaining these habits can be difficult in modern food environments, experts emphasize that consistent changes to diet, exercise, and alcohol consumption can significantly reduce the burden of high blood pressure and its life-threatening consequences.
