New Blood Pressure Guidelines Urge Caution and Lifestyle Changes

The next time you’re at the doctor’s office for a blood pressure check, you might notice a shift in how your provider approaches high readings. And if you enjoy unwinding with a glass of wine or a cocktail, you might want to rethink that. Recent guidelines from the American Heart Association and the American College of Cardiology advise, well, you might want to consider not drinking at all.

These heart organizations routinely analyze the latest research to assist medical professionals in managing high blood pressure effectively, but this update is their first since 2017. Given that heart disease remains the leading cause of death worldwide, controlling blood pressure is crucial. It can also reduce risks for kidney disease, type 2 diabetes, and even dementia.

Almost half of U.S. adults have blood pressure readings above the normal range. However, the target numbers remain unchanged: normal is under 120/80 mm Hg, and elevated ranges from 120-129/80 mm Hg. If your pressure hits 130/80 mm Hg or higher, expect your doctor to recommend some lifestyle changes.

To clarify, blood pressure is gauged in millimeters of mercury, noted as mm Hg. A reading includes a higher number, or systolic, and a lower number, or diastolic; the former reflects the force of blood when the heart beats, while the latter measures pressure when the heart relaxes.

Typically, high blood pressure sneaks up without noticeable symptoms. Yet, it puts extra strain on your blood vessels and heart, ultimately forcing both to work harder. If left untreated, chronic high blood pressure can damage arteries and elevate the risk of heart attacks or strokes.

The new guidelines suggest that for systolic readings in the 130 to 139 range, your medical provider should first advocate for lifestyle changes. If those adjustments don’t lower your pressure within three to six months, then medication may be necessary. This diverges from 2017’s guidance, which recommended medication at any systolic level above 140.

“We’re looking to more aggressively control blood pressure to improve outcomes for more people and lessen risks for cardiovascular diseases, strokes, and kidney diseases,” said Dr. Daniel Jones, chair of the writing committee for these guidelines. Interestingly, it’s now recognized that lowering blood pressure can also lower the risk of dementia.

The guidelines advocate lifestyle changes such as achieving a healthy weight, opting for a heart-healthy diet, cutting down on salt, managing stress, and getting at least 150 minutes of moderate exercise weekly, alongside some resistance training.

Another noteworthy change is the recommendation to avoid alcohol altogether, a departure from the previous suggestion allowing up to one drink daily for women and two for men. Dr. Jones pointed out a growing body of evidence indicating that alcohol adversely affects blood pressure.

“Many people enjoy their drinks, and while we acknowledge that, it’s important to make informed choices,” stated Jones, who is also an emeritus professor at the University of Mississippi School of Medicine. The guidelines call abstinence ideal, but if you do drink, aim for less than one for women and less than two for men.

Moreover, there is increasing recognition of the links between high blood pressure and dementia risk, and new emphasis on monitoring blood pressure for those considering or currently pregnant, given potential impacts on both the pregnancy and future health.

As for dietary recommendations, the guidelines still endorse the DASH diet, which emphasizes fruits, vegetables, whole grains, lean proteins, and healthy fats while minimizing sugar and unhealthy oils.

Jones reiterated the importance of limiting sodium intake, recommending under 2,300 mg each day, and ideally aiming for 1,500 mg. Increasing potassium is also advised, especially through potassium-enriched salt substitutes in home cooking.

For individuals who are overweight or obese, losing at least 5% of body weight is recommended. Those with more severe obesity may benefit from clinically proven interventions such as diet, exercise, or medications like GLP-1s, with surgery being an option for more extreme cases.

Jones acknowledges that managing blood pressure isn’t easy but emphasizes that implementing these suggestions can significantly enhance health. “The thing is, the first recommended steps for both prevention and treatment are about diet. Yet, we live in a tough food environment, making it challenging to maintain low sodium and adequate potassium levels. But if you’re committed to these changes, they do produce results,” he said. “It’s tough, but it works.”
