Hypertension, or high blood pressure, is a common health condition affecting about one in five adults in Canada. Alarmingly, around one-third of those with hypertension have uncontrolled blood pressure, and nearly one-fifth are unaware they have the condition. Because hypertension can lead to atherosclerosis – a major risk factor for premature death before age 65 – it is extremely important to be aware if your blood pressure is high and to take steps to manage it effectively.

Understanding the Risk Factors

If you are concerned that you or someone you care about may have hypertension, it is important to have your blood pressure measured and to also understand the risk factors. While your healthcare team can help assess your individual risk, common contributing factors include:

• Family history (genetics): Hypertension often runs in families and is more common in some populations due to genetic and environmental factors.
• Age: The risk of hypertension increases with age, particularly in women over the age of 55.
• Dietary habits: Eating a diet high in sodium or low in potassium can significantly raise blood pressure
• Excess body weight: Carrying extra body fat increases strain on the heart and blood vessels
• Low physical activity: Regular movement is essential for heart health and for maintaining a healthy blood pressure.
• Alcohol intake: Frequent or excessive alcohol consumption is linked to increased blood pressure.
• Smoking: Tobacco use damages blood vessels and contributes to hypertension
• Chronic stress: Ongoing stress can contribute to long-term elevated blood pressure.
• Underlying health conditions: Conditions such as diabetes, kidney disease, or sleep apnea are closely linked to hypertension.

If you identify with one or more of these risk factors, speak with a healthcare provider or your pharmacist to help you manage your individual risks.

What Is Your Blood Pressure?  

Blood pressure is measured using two numbers. For example, a reading of 120/80 mm Hg is considered healthy for most individuals. The systolic pressure (top number) indicates the pressure when your heart contracts and pushes blood into your arteries. The diastolic pressure (bottom number) reflects the pressure when your heart relaxes and fills with blood. If either number is higher than optimal, corrective steps should be taken.

High blood pressure causes damage to blood vessels over time, especially if left untreated. This can lead to complications such as stroke, heart attack, eye problems, dementia, kidney disease, heart failure, or erectile dysfunction.

The ideal blood pressure target varies depending on your personal health profile:

• For most people: below 140/90 mm Hg
• For individuals with diabetes: below 130/90 mm Hg
• For some people who are at high risk for heart disease: below 120 mmHg systolic

Your healthcare provider will guide you on the target that is right for you.

Monitoring Your Blood Pressure

Measuring your blood pressure at home can help you keep track of how well its being managed. Hypertension Canada has compiled a list of validated home monitors that meet current accuracy standards including a wide variety of models of arm and wrist monitors. View the list at https://hypertension.ca/public/recommended-devices. Or while shopping in store, look for recommended models with Hypertension Canada’s logo on the package. If you need help, your London Drugs pharmacist can help you select a monitor that will meet your personal needs.

When to take measurements

• Before taking your blood pressure medication
• Before breakfast or at least two hours after a meal
• After emptying your bladder and bowel if needed
• One hour after drinking coffee or smoking
• At least thirty minutes after exercise

How to measure blood pressure

• Sit quietly for 5 minutes before testing
• Sit upright with your back supported
• Keep your legs uncrossed and your feet flat on the floor
• Apply an appropriate sized blood pressure cuff on your bare arm, with lower edge of cuff 3 cm (1 inch) above the elbow
• Support your arm on a surface with middle of the cuff at heart level
• Avoid talking, moving, or distractions during the measurement and breathe normally
• Take 2 readings, one minute apart

How Can We Help?

You can’t treat a problem if you don’t know you have it. Raising awareness is the first step.

This spring and summer, select London Drugs locations will host Hypertension Awareness Clinics in partnership with Hypertension Canada, to help you learn more and to check your blood pressure. As part of your appointment, you may also choose to share your anonymous results with a global hypertension study conducted by the International Society of Hypertension. To date more than 100 countries have participated and more than 6 million individuals have been screened.

Speak to your London Drugs Pharmacist for advice on how to test your blood pressure and interpret the results. To find an appointment at a London Drugs Hypertension Awareness Clinic in your area, visit https://pharmacy.londondrugs.com/health-clinics/hypertension-awareness-clinics or ask at the pharmacy counter.

Even though high blood pressure produces no symptoms, it puts millions of Canadians at risk of health problems including heart attacks, strokes, and kidney failure. That’s why hypertension is often referred to as the ‘silent killer’, and it’s the leading risk factor for death worldwide. Nearly one-quarter of Canadian men (24%) and women (23%) have the condition, according to the latest stats. Fortunately, a simple blood pressure screening can prevent serious health risks and even death.

May 17th is World Hypertension Day

With World Hypertension Day on May 17^th, London Drugs pharmacists are reminding us all to get checked. This small action could be lifesaving if you’re one of the 7.5 million Canadians who have hypertension, or the 7.4 million more who have high blood pressure that will lead to hypertension without preventative action.

“Diagnosis and awareness of hypertension is critical to preventing future stroke, heart attack, and premature death,” says Gianni Del Negro, a Pharmacist at London Drugs. “A simple five-minute blood pressure check, easily accessible in the pharmacy, could help avoid the serious and deadly complications associated with hypertension.”

Detection of Hypertension is Easy

Luckily, detection of hypertension is straightforward and treatments are simple yet effective. London Drugs pharmacies offer complimentary blood pressure screening via in-store blood pressure kiosks, and pharmacists are available to discuss the results and answer any questions patients may have. They can also offer suggestions to minimize risk factors, which may include discussing changes to diet, fitness or lifestyle.

“Pharmacists are the most accessible health-care providers and we can offer advice for those who have high blood pressure or who are at risk,” explains Del Negro. “The sooner people are screened, the sooner we can begin working with them, and their physician, to find ways to reduce their risk.”

Home Monitors for Hypertension

Sharing readings from a home monitor with a pharmacist or physician is another way to monitor your health. At-home blood pressure monitors including those from Homedics, LifeSource, and Omron can help track your readings. Omron’s arm blood pressure monitor and wrist blood pressure monitor can even wirelessly transfer readings and track results with the free Omron Wellness App on your mobile device.

If you think you’re too young to start tracking your blood pressure, think again. New research shows that the vast majority (84%) of Canadians who have hypertension, are aware that they have the condition. Yet the research revealed the need for more awareness among younger Canadians; those aged 20 to 39 were much less likely to be aware of being hypertensive (65%) than those in older age groups. They were also less likely to be treated (55%) or to have their hypertension controlled (51%).

“This information underlines the importance of hypertension awareness and accessible blood pressure screenings to ensure Canadian adults, young and old, get their blood pressure checked,” says Del Negro.
