High blood pressure, often called the “silent killer,” poses significant health risks for people of all ages, but effective prevention and management strategies exist. Hypertension occurs when the force of blood against artery walls is consistently too high, forcing the heart to work harder and increasing the risk of heart disease, stroke, and other conditions. It is the leading risk factor for stroke and heart conditions such as coronary artery disease, heart failure, and atrial fibrillation. Emerging evidence also links high blood pressure to cognitive decline and dementia, underscoring the need for awareness and proactive management.
Anyone can develop high blood pressure, making regular checkups essential. The American Heart Association recommends blood pressure measurements at annual physicals for all age groups, including children and young adults. Those with risk factors—such as excess weight, diabetes, high cholesterol, smoking, lack of physical activity, alcohol consumption, and a diet high in sodium and low in potassium—may require more frequent monitoring. Alarmingly, nearly half of U.S. adults have high blood pressure, and about 75% of those do not have it under control. Because it typically shows no symptoms, many are unaware of their condition.
To obtain an accurate reading, individuals should sit in a chair with back support and feet flat on the ground, using a validated, automatic, cuff-style upper-arm monitor. After removing clothing over the arm and resting for at least five minutes, the arm should be extended and supported at heart level while remaining quiet and still. Multiple readings should be taken and recorded at the same time each day. For most adults, a normal blood pressure reading is less than 120/80 mm Hg.
If diagnosed with high blood pressure, quick action can significantly lower the risk of heart attack and stroke. A healthcare professional can design a treatment plan that may include lifestyle changes and medication. Prevention is also possible through small steps such as eating a heart-healthy diet, staying active, and maintaining a healthy weight. For those already diagnosed, maintaining a healthy weight by engaging in at least 150 minutes of moderate activity per week and eating a balanced diet rich in fruits, vegetables, lean protein, and whole grains is crucial. Even losing 5% of body weight can improve blood pressure. Reducing or avoiding alcohol and tobacco, along with stress-reducing activities like meditation, breathing control, or yoga, are also beneficial. Adhering to prescribed medications is often essential for effective control. For more information on blood pressure management, visit heart.org/bp.
