High blood pressure, also called hypertension, becomes more common as people grow older. If it is not controlled, it can increase the risk of heart attacks, strokes, heart failure, kidney disease, and other serious health problems.
At the same time, lowering blood pressure too much can also cause problems, especially in older adults.
When blood pressure drops too low, people may feel dizzy or lightheaded. Some may faint or lose their balance, increasing the risk of falls and broken bones. Because these injuries can greatly affect a person’s independence and quality of life, doctors try to find a treatment plan that protects both the heart and overall well-being.
For many years, doctors recommended keeping the top blood pressure number, known as systolic blood pressure, below 140 mmHg. This target was considered a good way to lower the risk of heart disease while avoiding too many side effects from treatment.
More recently, however, researchers have questioned whether even lower blood pressure might provide greater protection.
One of the most influential studies on this topic is the Systolic Blood Pressure Intervention Trial, better known as the SPRINT trial. The study included adults over 50 years of age who had a higher risk of heart disease but did not have diabetes. Researchers compared people whose systolic blood pressure was treated to below 140 mmHg with those whose target was below 120 mmHg.
The results showed that participants in the lower blood pressure group had fewer heart attacks, fewer strokes, and fewer deaths related to heart disease. These findings suggested that more intensive blood pressure treatment could improve long-term health and help some people live longer. The study changed the way many experts think about blood pressure goals.
However, the research also found important downsides. People aiming for a systolic blood pressure below 120 mmHg were more likely to experience dizziness, fainting, kidney problems, and low blood pressure. These side effects were especially important for older adults because they increased the risk of falls and other complications.
Because of these findings, many experts no longer believe there is one perfect blood pressure target for every person over 60. Instead, doctors recommend considering each person’s age, overall health, medical conditions, medicines, and risk of side effects. Treatment should be tailored to the individual rather than following the same goal for everyone.
For many healthy older adults, keeping systolic blood pressure between 120 and 130 mmHg may provide a good balance between lowering the risk of heart disease and avoiding unwanted side effects.
However, some people, including those with diabetes, kidney disease, or other medical conditions, may need different treatment goals. Decisions should always be made together with a healthcare professional.
Medicine is only one part of controlling blood pressure. Eating a balanced diet, reducing salt intake, staying physically active, maintaining a healthy weight, limiting alcohol, avoiding smoking, and managing stress can all help improve blood pressure naturally. Regular check-ups also allow doctors to adjust treatment as health needs change over time.
The most important message is that successful blood pressure treatment is not about reaching one magic number. It is about finding the safest and most effective target for each individual. By working closely with their healthcare team and maintaining healthy lifestyle habits, older adults can lower their risk of serious disease while continuing to enjoy active and independent lives.
