If the pressure in heating pipes becomes too high, the boiler gives a message. But the pipe system in our body only gives complaints when it is too late. How do you know if your blood pressure is still healthy? Do you notice


1. What exactly is blood pressure?

blood pressure

Our blood circulation is a kind of artwork. On average, we have about 5 liters of blood that is circulated through the system of blood vessels to the smallest blood vessels. Every time the heart contracts, the blood is

vigorously sprayed through the vessels, like the water through the garden hose. This creates pressure on those vessels: blood pressure.

When the heart squeezes, the blood pressure is highest and the upper pressure is measured. When the heart is at rest, the blood pressure is the lowest and the negative pressure is measured.

2. When is it too high?

If the upper pressure is on average above 140 and the under pressure is above 90 (140/90 mmHg), there is a high blood pressure or hypertension.

sliding scale, healthy blood pressure is 120 over 80. With every point increase, the risk of death and health problems such as stroke and dementia increase. This risk is considerably smaller if you bring and keep the upper

pressure under 140. The elderly guidelines for health care are exempted: they aim for an upper pressure of a maximum of 150, provided that the blood pressure is lowered brought. “

3. What happens to your vessels if the blood pressure is too high?

Ideally, the walls of the arteries are smooth and elastic. For such lean blood vessels, it is no problem to widen if more blood needs to pass through, for example if you ride hard. But blood vessels can stiffen and then they

absorb pressure changes less well. If the vessel walls are less flexible, a blood vessel gives more resistance. It does not stretch itself, so the blood has to pass through a narrower tube. With the result: a higher blood

pressure in the entire body.

4. Do you notice anything?

Nothing. That is precisely the problem. High blood pressure does not cause symptoms in itself, but it is a cause of other health problems.

5. What are the consequences?

The longer the arteries are under high pressure, the less flexible and elastic they become. This increases the resistance in the arteries. This creates a vicious circle: the high blood pressure strengthens itself. Eventually, the

artery wall becomes damaged and, for example, arterial calcification can occur.

The heart muscle also suffers from high blood pressure. The heart constantly has to ‘pump’ against the high pressure and as a result the muscle becomes overloaded.

Blood pressure expert Wilko Spiering: “The most feared complication of high blood pressure is stroke , heart attacks, cardiac arrhythmia and heart failure are common, high blood pressure is by far the most important cause of

death worldwide, and ten million people die every year from diseases that are caused by high blood pressure. . ” In addition to damage to the heart and blood vessels, high blood pressure can also lead to damage to the

kidneys and eyes. Blood vessels can also rupture due to the constantly high pressure.
