High blood pressure, also called hypertension, is one of the most common health problems around the world.
It affects millions of adults and can quietly damage the body for many years before any symptoms appear.
Because of this, high blood pressure is often called the “silent killer.”
If it is not treated, it can increase the risk of heart attacks, strokes, heart failure, kidney disease, and vision problems.
Fortunately, modern medicines and healthy lifestyle habits have helped many people control their blood pressure and live longer, healthier lives.
Doctors usually treat high blood pressure with medicines such as diuretics, ACE inhibitors, beta-blockers, calcium channel blockers, and angiotensin receptor blockers, also known as ARBs.
Each type works in a different way to lower blood pressure.
Among these, ACE inhibitors and ARBs are especially popular because they not only lower blood pressure but also protect the heart and kidneys in many patients, particularly those with diabetes or heart disease.
However, new research suggests that scientists still have much to learn about how these medicines affect the body over many years. Researchers at the University of Virginia have discovered that long-term use of medicines that target the renin-angiotensin system may cause unexpected changes inside the kidneys. Their findings were published in the journal JCI Insight.
The research team was led by Dr. Maria Luisa Sequeira Lopez. They focused on special kidney cells called renin cells. These cells are an important part of the body’s natural system for controlling blood pressure. They help produce renin, a hormone that starts a chain of reactions that helps regulate blood pressure, fluid balance, and the amount of salt in the body.
The scientists found that when ACE inhibitors or ARBs are used for a long time, renin cells may begin to behave differently. Instead of remaining in their normal location, some of these cells move into the walls of blood vessels inside the kidneys.
As more renin cells build up there, the walls of the blood vessels may become thicker and less flexible. Over time, these changes could reduce blood flow inside the kidneys and may affect how well the kidneys work.
This discovery is important, but it should not cause people to stop taking their blood pressure medicines. The study does not show that these medicines are unsafe or that everyone who takes them will develop kidney problems.
In fact, ACE inhibitors and ARBs have saved countless lives by lowering the risk of heart attacks, strokes, and serious complications from high blood pressure. For many people, their benefits are much greater than any possible risks.
Instead, the study highlights the need for more research. Scientists want to understand why these kidney changes happen, whether they occur in all patients or only some people, and whether new treatments could prevent them. Future studies may also help doctors decide which patients would benefit most from different types of blood pressure medicines.
If you have high blood pressure, the best thing you can do is continue taking your medicine exactly as prescribed unless your doctor tells you otherwise.
Regular medical check-ups are also important because they allow your healthcare provider to monitor your blood pressure, kidney function, and overall health. Checking your blood pressure at home with a reliable monitor can also help you and your doctor see how well your treatment is working.
Healthy lifestyle habits remain a key part of blood pressure control. Eating more fruits, vegetables, whole grains, and low-fat dairy foods, reducing salt intake, exercising regularly, maintaining a healthy weight, avoiding smoking, limiting alcohol, getting enough sleep, and managing stress can all help lower blood pressure naturally. These habits also improve heart health and reduce the risk of many other diseases.
The new findings remind us that treating high blood pressure is about much more than lowering the numbers on a blood pressure monitor. The goal is to protect the entire body, including the heart, brain, kidneys, and blood vessels, for many years to come.
As researchers continue to learn more about these medicines, doctors will be able to make treatment even safer and more effective. For now, patients should stay informed, attend regular check-ups, and work closely with their healthcare team to find the treatment plan that is best for them.
If you care about high blood pressure, please read studies that early time-restricted eating could help improve blood pressure, and natural coconut sugar could help reduce blood pressure and artery stiffness.
For more health information, please see recent studies about added sugar in your diet linked to higher blood pressure, and results showing vitamin D could improve blood pressure in people with diabetes.
