High blood pressure, also known as hypertension, affects millions of people around the world. It happens when blood pushes too hard against the walls of the arteries over a long period.
If it is not controlled, it can damage the heart, brain, kidneys, and other organs, raising the risk of heart attacks, strokes, and kidney failure.
For many people, blood pressure can be lowered with healthy eating, regular exercise, weight control, and medicines.
However, some people continue to have high blood pressure even though they take several blood pressure medicines. This condition is known as resistant hypertension and needs careful medical attention.
Resistant hypertension is more than simply having high blood pressure. It may mean that the current treatment plan is not working as expected or that another hidden problem is keeping blood pressure high. Finding the reason is important because this condition greatly increases the risk of serious heart and blood vessel diseases.
Before diagnosing resistant hypertension, doctors first make sure the blood pressure readings are accurate. Some people experience ‘white coat hypertension,’ where their blood pressure rises only during a visit to the doctor’s office because they feel nervous. Blood pressure can also appear high if it is not measured correctly or if medicines are not taken as prescribed.
If resistant hypertension is confirmed, doctors often begin by looking at everyday habits. Reducing salt in the diet can make a meaningful difference because too much sodium causes the body to hold extra fluid, increasing blood pressure. Regular physical activity also helps keep the heart and blood vessels healthy and can naturally lower blood pressure over time.
Doctors also check for other medical conditions that can make blood pressure difficult to control. Being overweight, kidney disease, and obstructive sleep apnea are common examples. Treating these conditions may improve blood pressure as well. For example, many people with sleep apnea see improvements after using a CPAP machine during sleep.
Medicines remain an important part of treatment. Sometimes the key is choosing the right combination of drugs rather than simply adding more medicines. Diuretics help the body remove extra salt and water, and research has shown that spironolactone can be especially effective for many people with resistant hypertension.
When lifestyle changes and medicines are still not enough, doctors may consider newer treatment options. One of the most promising is renal denervation, a procedure that uses radiofrequency energy to reduce nerve signals connected to the kidneys. Early clinical studies suggest it may help lower blood pressure in some patients who have not responded well to standard treatments.
Understanding resistant hypertension is important because controlling blood pressure can greatly reduce the risk of heart disease and stroke.
Anyone whose blood pressure remains high despite treatment should speak with their healthcare provider about possible causes and treatment options. With the right plan, many people can achieve better blood pressure control and improve their long-term health.
