Blood pressure: a brief introduction
If you have ever been to the doctor, your blood pressure will certainly have been measured. Blood pressure is the pressure of the blood against the walls of your arteries. It is expressed in two numbers: the systolic (upper) value and the diastolic (lower) value. But what do these numbers actually mean?
The meaning of the numbers
The systolic value indicates how much pressure your heart generates when it pumps blood into your body. A normal systolic value is 120 mmHg. The diastolic value measures the pressure in the arteries when the heart relaxes between beats. A normal diastolic value is 80 mmHg. The unit of measurement for blood pressure is mmHg, which is millimeters of a column of mercury that rises as the pressure is transferred to the column of mercury. Hg is the chemical abbreviation for mercury.
A blood pressure value of 120/80 mmHg is therefore considered "normal". But if one of these values is regularly too high, it is known as high blood pressure or hypertension. Conversely, blood pressure that is too low, known as hypotension, can also cause health problems.
Why is the right blood pressure so important?
Consistently high blood pressure can lead to cardiovascular disease, kidney damage and other serious health problems. On the other hand, low blood pressure can lead to dizziness, lightheadedness and fainting. The right balance is therefore crucial for your health.
What can you do?
If you have your blood pressure checked regularly and eat a healthy diet, get enough exercise and reduce stress, you are well on the way to keeping your values in the green zone. However, if you are concerned or already have problems, you should definitely speak to a doctor. They can help you find the best measures for your specific situation.
