Hypertension, or high blood pressure, is a silent threat affecting millions of Canadians. Often showing no symptoms, it can significantly increase your risk of heart disease, stroke, kidney disease, and other serious health complications. Raising awareness and understanding of hypertension is crucial for prevention, early detection, and effective management. This guide will provide you with essential information about hypertension in Canada, empowering you to take control of your health.
What is hypertension?
So, what exactly is hypertension? Hypertension occurs when the force of your blood against your artery walls is consistently too high. This sustained pressure can damage your heart, blood vessels, and other organs over time. Blood pressure readings are expressed with two numbers: systolic (the pressure when your heart beats) and diastolic (the pressure when your heart rests between beats). A normal blood pressure reading is typically below 120/80 mmHg. Hypertension is generally diagnosed when readings consistently reach 140/90 mmHg or higher.
Several factors can contribute to the development of hypertension. These include:
- Age: The risk of hypertension increases with age.
- Family History: Having a family history of hypertension increases your risk.
- Lifestyle Factors: Unhealthy lifestyle choices such as a diet high in sodium, lack of physical activity, excessive alcohol consumption, and smoking can significantly contribute to the development of hypertension.
- Obesity: Being overweight or obese increases the risk of hypertension.
- Underlying Conditions: Certain medical conditions, such as kidney disease and sleep apnea, can also contribute to hypertension.
What can hypertension cause?
The insidious nature of hypertension lies in its lack of early warning signs. You might feel perfectly fine while high blood pressure is silently damaging your body. Left untreated, hypertension can lead to serious health complications, including:
- Heart Disease: Hypertension strains your heart, increasing the risk of heart attack, heart failure, and stroke.
- Stroke: High blood pressure can weaken blood vessels in the brain, increasing the risk of rupture and stroke.
- Kidney Disease: Damaged blood vessels can impair kidney function, potentially leading to kidney failure.
- Vision Loss: Hypertension can damage blood vessels in the eyes, leading to vision problems and even blindness.
- Peripheral Artery Disease (PAD): High blood pressure can contribute to the narrowing of arteries in your limbs, leading to pain, numbness, and even amputation.
- Sexual Dysfunction: Hypertension can affect blood flow to the sexual organs, leading to difficulties.
What are the signs of hypertension?
So, what are the signs of hypertension to be aware of? While many people with high blood pressure experience no symptoms at all, some may exhibit the following:
- Severe Headaches: Persistent and severe headaches, especially those that are different from your usual headache pattern, could indicate a hypertensive crisis. Don’t dismiss recurrent, intense headaches.
- Nosebleeds: Frequent nosebleeds, particularly those that are difficult to stop, can sometimes be a sign of uncontrolled high blood pressure. While nosebleeds are often benign, it’s worth investigating if they occur frequently and are accompanied by other potential symptoms.
- Dizziness: While dizziness can be caused by various factors, persistent or severe dizziness, especially when accompanied by other symptoms like headaches or blurred vision, warrants a medical checkup.
- Blurred Vision or Visual Disturbances: High blood pressure can damage the blood vessels in the eyes, leading to blurred vision, double vision, or even vision loss. Any sudden changes in vision should be addressed immediately by a medical professional.
- Shortness of Breath: In some cases, untreated hypertension can lead to heart failure, which can cause shortness of breath, especially during physical activity or when lying down.
- Chest Pain: While chest pain is a common symptom of heart problems, it can also be associated with severe hypertension, particularly if it’s accompanied by other symptoms like shortness of breath or dizziness.
It’s important to remember that experiencing one or more of these symptoms doesn’t automatically mean you have hypertension. However, if you regularly experience any of these issues, or if you are at risk for high blood pressure due to factors like age, family history, obesity, or unhealthy lifestyle choices, it’s crucial to consult your doctor and have your blood pressure checked regularly.

Taking Control: Prevention and Management Strategies
While some risk factors for hypertension, such as age and family history, are beyond your control, you can significantly reduce your risk and manage existing hypertension through lifestyle modifications and, when necessary, medication.
Lifestyle Modifications:
- Healthy Diet: Adopt a heart-healthy diet that is rich in fruits, vegetables, and whole grains. Limit your intake of sodium, saturated fats, and cholesterol. The Dietary Approaches to Stop Hypertension (DASH) diet is a well-researched and effective dietary pattern for lowering blood pressure.
- Regular Exercise: Aim for at least 150 minutes of moderate-intensity aerobic exercise or 75 minutes of vigorous-intensity aerobic exercise per week. Activities like brisk walking, jogging, swimming, and cycling are excellent choices.
- Weight Management: Maintaining a healthy weight is crucial for managing blood pressure. If you are overweight or obese, losing even a small amount of weight can have a significant impact.
- Limit Alcohol Consumption: Excessive alcohol consumption can raise blood pressure. Limit yourself to no more than one drink per day for women and two drinks per day for men.
- Quit Smoking: Smoking damages blood vessels and increases the risk of hypertension and other cardiovascular diseases. Quitting smoking is one of the best things you can do for your health.
- Manage Stress: Chronic stress can contribute to high blood pressure. Find healthy ways to manage stress, such as yoga, meditation, or spending time in nature.
- Monitor Blood Pressure at Home: Regular home blood pressure monitoring can help you track your progress and identify any potential problems. Consult with your doctor or pharmacist about the best way to monitor your blood pressure at home.
Medication:
In addition to lifestyle modifications, your doctor may prescribe medication to help lower your blood pressure. There are several types of antihypertensive medications available, including:
- Diuretics: These medications help your body eliminate excess sodium and water.
- ACE Inhibitors: These medications block the production of a substance that narrows blood vessels.
- Angiotensin II Receptor Blockers (ARBs): These medications block the action of a substance that narrows blood vessels.
- Beta-Blockers: These medications slow down your heart rate and lower blood pressure.
- Calcium Channel Blockers: These medications relax blood vessels.
It’s crucial to take your medication as prescribed and to follow up with your doctor regularly to monitor your blood pressure and adjust your medication as needed. Never stop taking your medication without consulting with your doctor first.
