High Blood Pressure (Hypertension)
Treatment Overview
Treatment for high blood pressure depends on the severity of the disease and whether you have other health problems, such as heart failure or diabetes, or you are pregnant. Your doctor may want you to try lifestyle changes first, including losing weight, increasing activity, and eating a balanced diet. If your blood pressure is above a certain level, your doctor may prescribe medicine along with the lifestyle changes.
Some people may only need lifestyle changes to control their high blood pressure, while others need medicine as well. Either way, treating high blood pressure usually is a lifelong process.
Treatment of primary high blood pressure, especially moderate or severe high blood pressure, decreases the risk of heart failure, coronary artery disease, heart attack, abnormal heartbeats, stroke, and kidney disease, and it reduces the risk of death from these conditions.
Overall, goals of treatment are to:
- Prevent death and disease associated with high blood pressure (heart disease, stroke, and kidney disease). High blood pressure is associated with 35% of heart disease caused by coronary artery disease and 49% of all cases of heart failure.9
- Reduce systolic blood pressure below 140 millimetres of mercury (mm Hg) and diastolic blood pressure below 90 mm Hg. Studies have shown that lowering high blood pressure even further can lower the risk of death in people with diabetes and coronary artery disease.10, 11 Lowering blood pressure in people with kidney disease can help keep the kidneys working. In these people, blood pressure should be lowered to less than 130/80 mm Hg.
- Control other risk factors, such as smoking, lack of exercise, and high cholesterol, that can lead to complications such as a heart attack and stroke.
- Minimize side effects of medicines.
- Live a full and active life.
Initial treatment
If you fall into the high-normal range (130–139/85–89), your doctor will likely recommend lifestyle changes, including:
- Losing excess weight.
- Exercising.
- Limiting alcohol to 2 drinks
a day for men, and 1 drink a day for women.
- Cutting back on salt.
- Quitting smoking.
- Following the Dietary Approaches to Stop Hypertension (DASH) diet.
This eating plan is a low-fat and low-saturated-fat diet that emphasizes eating more fruits, vegetables, whole grains, and low-fat dairy foods. For more information, see:
If you have high blood pressure (140–159/90–99 mm Hg) and you do not have any organ damage or other risk factors for heart disease (this is called uncomplicated high blood pressure), your doctor will likely recommend lifestyle changes and possibly medicines. Most people with high blood pressure will need two or more medicines, including a thiazide-type diuretic, to lower their blood pressure to below 140/90 mm Hg, which is the goal for people with uncomplicated hypertension. If you have other conditions, such as diabetes, heart failure, or chronic kidney disease, your goal blood pressure is lower: 130/80 mm Hg. For more information, see:
If your blood pressure is 160–179/100–109 mm Hg or higher, you may need to try various combinations of medicines to find what works best for you. You will also need to make aggressive lifestyle changes.

Treatment of secondary high blood pressure varies depending on the cause. For example, treatment of high blood pressure caused by kidney disease will also include treating the kidney problem. If you have secondary high blood pressure, you may have to take blood pressure medicine long term, even if the underlying condition is treated.
For more information, see the high blood pressure guidelines from Canadian and U.S. expert committees.
People with high blood pressure who require special treatment considerations include:
Ongoing treatment
Most cases of high blood pressure cannot be cured but can be controlled with lifestyle changes and medicine. Treatment is a lifelong process.
You may need to try several different medicines or combinations of medicines, such as ACE inhibitors and diuretics, before finding the right combination that lowers your blood pressure to a safe level. If you have secondary high blood pressure, you may need treatment for the underlying condition. For more information on medicines, see:
You may need to work with a registered dietitian to successfully follow the Dietary Approaches to Stop Hypertension (DASH) diet. For more information, see:
It is important to follow the lifestyle changes your doctor recommends for the rest of your life to reduce your risk of heart disease and stroke.
People with heart disease and high blood pressure have a high risk for future heart problems and need aggressive treatment.12
Treatment if the condition gets worse
Untreated high blood pressure can lead to fatal heart attacks or strokes. The higher your blood pressure, the greater your risk for these complications. Lowering blood pressure reduces the risk of damaging blood vessels and developing atherosclerosis.
As your high blood pressure rises, you may need to take higher doses of medicine or a combination of medicines. Many people take a combination of several medicines.

What to Think About
In older adults, even small decreases in systolic blood pressure may be enough to prevent complications, if their diastolic blood pressure is normal.
People who have high blood pressure are encouraged to make lifestyle changes and stick with them for the rest of their lives to reduce their blood pressure. Lifestyle changes such as eating a low-fat diet, quitting smoking, and exercising will help reduce the overall risk of heart disease and stroke and may reduce blood pressure significantly.
