Hypertension or high blood pressure is the leading cause of preventable early death globally. It’s preventable because hypertension, once diagnosed, can be treated. Effective and early treatment reduces the risk of having a cardiovascular event such as a heart attack or stroke.
In Canada, over half of adults are hypertensive or pre-hypertensive, primarily due to aging, genetics and lifestyle factors like diet and a sedentary lifestyle.
The most important step you can take is to measure and monitor your blood pressure regularly and create a plan with your doctor to treat your blood pressure if it gets too high. Knowledge is power. Understanding how your body works (or when it needs a tune-up) can help you make proactive, empowered and personalized decisions about your health and well-being.
Hypertension Fast Facts
What is blood pressure?
Blood pressure is the force blood exerts against blood vessels after the heart pumps it. This force created by the heart is important to circulate blood throughout the body. When blood pressure is taken two values are recorded; systolic (SBP) and diastolic blood pressure (DBP). When you receive a blood pressure reading it will be recorded with two numbers, like so, 120/80 mmHg, and verbalized as “120 over 80”. The first number is your SBP and the second number is your DBP.
What do systolic blood pressure and diastolic blood pressure mean?
What is hypertension?
Hypertension occurs when there is too much pressure in the blood vessels. This can happen for several reasons; the most common cause is the stiffening of blood vessels due to aging and/or build-up of atherosclerotic plaques. With increased stiffness or blockages, the heart must work harder to push blood through the arteries. When there is too much force, the blood vessels can become damaged, increasing the risk for various health issues including heart attacks and stroke.
How high is too high?
The first line treatment for patients with moderate risk is lifestyle modification. Hypertension Canada names physical activity, weight reduction, smoking cessation, reduced sodium intake and other dietary changes as key lifestyle modifications. These healthy behaviours are critical at all stages of hypertension care but can be the sole intervention for those at moderate risk.
A medical doctor will typically begin pharmaceutical treatment for hypertension when blood pressure levels reach 140/90 mmHg or greater. Treatment may be started at lower numbers if an individual has other health conditions such as diabetes or a history of stroke.
In some cases, a medical doctor will give a patient a window of time to decrease their blood pressure with lifestyle modifications before pharmaceutical treatment is initiated. This depends on personal medical history and risk factors.
PreCardix®, a natural ACE inhibitor, is a great addition for those in the moderate risk category or for those given that window of time to reduce their blood pressure before pharmaceuticals are initiated. PreCardix® is clinically proven to lower blood pressure safely and effectively within eight weeks without serious side effects.
Hypertension Canada recommends the following actions be taken based on blood pressure readings.
What causes hypertension?
Hypertension Canada breaks down the risk factors or causes of hypertension into two categories:
Managing these factors, can help decrease your blood pressure. The table below illustrates the impact modifying these factors has on blood pressure. If you are feeling overwhelmed by making many changes all at once, start with one or two interventions and add more when you are ready. PreCardix® is a great way to kick-start these lifestyle changes. In clinical research, 89% of participants experienced a significant blood pressure lowering effect of >5mmHg. Each small step is helpful when it comes to hypertension and may also give you the boost in energy and confidence to take on more healthy habits.
To put these values in perspective a 5mmHg reduction in blood pressure leads to a:
This shows how many opportunities we have to positively impact our heart health and overall wellbeing!
While we can’t change these factors, we can delay and positively influence their impact. Knowing you have a family history of hypertension may inspire you and your doctor to start monitoring your blood pressure at an earlier age and incentivize you to make changes to any of the modifiable risk factors discussed above! Even making one change can significantly decrease your risk of developing hypertension.
Why does blood pressure change throughout the day?
Blood pressure naturally fluctuates throughout the day. It is typically lowest when you are sleeping or relaxing and highest in the morning or when you are under physical stress, including exercising. If you’re monitoring your blood pressure at home make sure to take it at the same time each day, preferably in the morning when it’s highest. Check out this blog for more information on understanding your numbers.
Should I take my blood pressure at home?
Monitoring your blood pressure is an important healthy habit to get into whether you have hypertension or not. It becomes especially important as you age and if you have other risk factors for developing hypertension like those listed above. If you take your blood pressure consistently you can identify unusual changes like higher than normal values or significant swings. If either of these trends are identified it’s important to consult your doctor. Stroke and heart attack can be avoided by properly managing hypertension. Follow this guideline for correct blood pressure monitoring at home and record your results with our simple blood pressure tracking app.
What do I do if I get a high blood pressure reading?
If your reading is slightly or moderately higher than usual, take it a few more times and record the results. Contact your doctor with this information to verify if it’s a concern or not. If your blood pressure exceeds 180/120 mmHg, wait 5 minutes and then take the reading again. If your reading remains high you may be experiencing a hypertensive crisis and should contact your doctor immediately.
Measure, plan and monitor.
Whether you currently have high blood pressure or are looking to reduce your risk of developing it, there are simple steps you can take. Working to improve your modifiable risk factors through diet, exercise, clinically supported natural health products like PreCardix® and well-managed chronic conditions can be tremendously beneficial for your overall health.
Taking daily blood pressure readings will give insight into your body and help identify any deviations from your normal before major problems arise. Understanding what hypertension is and what your blood pressure readings mean will help you make empowered decisions about your health.
