Understanding Hypertension: Causes, Symptoms, and Treatment Options in the GTA

Introduction

Hypertension, or high blood pressure, is one of the most common and dangerous health conditions affecting residents in Brampton, Mississauga and Milton. Often referred to as the “silent killer,” hypertension can lead to serious cardiovascular problems such as heart disease, stroke, and kidney failure if left untreated. 

What is Hypertension?

Hypertension is a condition where the force of the blood against the walls of your arteries is consistently too high. Blood pressure is measured in millimeters of mercury (mmHg) and is recorded with two numbers:

• Systolic pressure (the top number) measures the pressure in your arteries when your heart beats.
• Diastolic pressure (the bottom number) measures the pressure in your arteries between heartbeats.

A normal blood pressure reading is typically around 120/80 mmHg. Hypertension is generally diagnosed when readings are consistently 130/80 mmHg or higher. Left untreated, high blood pressure can lead to heart disease, kidney damage, and other serious health complications.

Causes of Hypertension

Hypertension may develop due to a combination of lifestyle factors, underlying health conditions, and genetic factors. Here are some common causes and risk factors for hypertension:

1. Unhealthy Diet: High salt intake, excessive consumption of processed foods, and a diet high in unhealthy fats can contribute to high blood pressure.
2. Lack of Physical Activity: Sedentary lifestyles can lead to weight gain and contribute to high blood pressure.
3. Excessive Alcohol Consumption: Drinking too much alcohol can raise blood pressure.
4. Obesity: Carrying excess weight puts additional strain on the heart and increases the risk of hypertension.
5. Stress: Chronic stress and anxiety can temporarily increase blood pressure, and over time, may contribute to long-term hypertension.
6. Smoking: Smoking damages blood vessels and raises blood pressure.
7. Family History: Hypertension can run in families, meaning your genetic makeup may play a role in your risk.

Symptoms of Hypertension

Hypertension is often called a “silent” condition because it usually doesn’t present obvious symptoms. Many people with high blood pressure feel perfectly fine, which is why it’s crucial to have regular check-ups. However, in severe cases, individuals with uncontrolled hypertension may experience symptoms like:

• Headaches
• Dizziness or lightheadedness
• Shortness of breath
• Chest pain
• Nosebleeds
• Fatigue

If you experience any of these symptoms, it’s important to see a healthcare provider immediately for a thorough assessment.

The Risks of Untreated Hypertension

Untreated hypertension can significantly increase your risk of serious health complications, including:

• Heart Disease: High blood pressure can lead to the hardening of the arteries (atherosclerosis), heart attack, heart failure, and other cardiovascular issues.
• Stroke: High blood pressure can damage and weaken blood vessels in the brain, leading to the increased risk of stroke.
• Kidney Damage: Hypertension can damage the kidneys and lead to kidney disease or kidney failure.
• Vision Loss: Damage to the blood vessels in the eyes can cause vision problems and even blindness.

Managing Hypertension: Treatment Options

The good news is that hypertension can be managed effectively with lifestyle changes and medication. Here are the key treatment options for hypertension:

1. Lifestyle Modifications

A healthy lifestyle is the foundation of managing and preventing hypertension. The following changes can significantly reduce your risk of developing high blood pressure or help control an existing diagnosis:

• Eat a Healthy Diet: Focus on a balanced, low-sodium diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats. The DASH (Dietary Approaches to Stop Hypertension) diet is particularly effective in lowering blood pressure.
• Exercise Regularly: Engaging in regular physical activity—such as walking, jogging, cycling, or swimming—helps reduce blood pressure and improve heart health. Aim for at least 30 minutes of exercise most days of the week.
• Limit Alcohol Consumption: If you drink alcohol, do so in moderation. Excessive alcohol intake can elevate blood pressure.
• Quit Smoking: Smoking contributes to the narrowing of blood vessels and raises blood pressure. Quitting smoking can help lower your blood pressure and improve overall cardiovascular health.
• Manage Stress: Practice stress-reducing techniques such as meditation, yoga, or deep breathing exercises to help keep your blood pressure under control.

2. Medications for Hypertension

For some individuals, lifestyle changes alone may not be enough to manage blood pressure. In such cases, medication may be prescribed. Common types of medications used to treat hypertension include:

• Diuretics: Help reduce the amount of fluid in your blood vessels, which lowers blood pressure.
• ACE Inhibitors: Relax blood vessels by blocking the enzyme that narrows them, improving blood flow.
• Beta-Blockers: Reduce the heart rate and the heart’s workload, lowering blood pressure.
• Calcium Channel Blockers: Relax and widen the blood vessels, which can help lower blood pressure.
• Angiotensin II Receptor Blockers (ARBs): Help relax blood vessels and reduce blood pressure.

Your healthcare provider will work with you to determine the most appropriate medication based on your individual health needs.
