Why it is important to get checked

Hypertension is usually discovered fortuitously during a routine examination, but the first time someone finds out that they have high blood pressure is often when they are taken to hospital because it has led to a stroke or a heart problem.

Indeed, hypertension is said to be a silent disease that can be fatal, because it often has no warning signs or symptoms. Yet up half to the people with hypertension may be unaware they have it, as they do not exhibit signs or symptoms. This is why hypertension is considered as a global public health issue.
The only way to know whether a person has hypertension is by having their blood pressure checked.For that very reason, it is recommended that you get your blood pressure checked routinely at least every 5 years if you are over 40 years of age, or more often if you have high blood pressure, in accordance with your health care team.1,2,3

How can hypertension affects your body?

When you have hypertension, your heart has to work harder to ensure the flow of blood around your body. Over time, this high pressure can gradually weaken your heart and damage artery walls, leading to changes in blood flow. All these situations lead to an increased risk of developing cardiovascular disease (stroke, heart disease, and heart failure). Other parts of the body, including the kidneys, limbs, and eyes, may also suffer damage.5

Once you know that you have high blood pressure, the good news is that you and your doctor can take steps to control it.

How often should I see my GP about hypertension?

Depending on your age, once every 2 years is considered adequate. Still, if you are over 40 years of age, once a year is a safer option. If you have already been diagnosed with abnormal blood pressure, tests should be more frequent, as per your doctor’s recommendations.14
