Many people still believe that there is a connection between blood pressure and dizziness. Why? And if so, what is the link between dizziness and blood pressure? The following article will help us understand more about this issue.

1. What is high blood pressure?

High blood pressure is a common disease in the elderly, obese or people with certain medical conditions such as diabetes, high blood fat or genetic factors.
Blood pressure increases when the force exerted on the artery walls of the blood increases, the pressure of the blood is so high that the heart has to work harder to get enough blood to supply and pump around the body. High blood pressure can cause a stroke.
Normal blood pressure is 120/80 mmHg (systolic/diastolic pressure).
If your blood pressure is between 120/80 mmHg and 139/89 mmHg it is called prehypertension (at risk of high blood pressure). If the blood pressure level is 149/90 mmHg or higher, it is called high blood pressure.

2. What is low blood pressure?

Low blood pressure usually has a systolic pressure of less than 90 mmHg and a diastolic pressure of less than 60 mmHg.
Patients with low blood pressure due to certain medical conditions often have a sudden drop in blood pressure that is normal or may be pre-existing high, usually from 30-40 mmHg.
Low blood pressure greatly affects health, especially for the elderly.

3. The relationship between dizziness and blood pressure

Low blood pressure and high blood pressure both have a connection with feeling dizzy. However, only some people experience dizziness due to high blood pressure or low blood pressure, the majority of which are caused by other causes.
Dizziness and low blood pressure: Some people with low blood pressure (ie less than 100 mmHg) may feel dizzy. This case of dizziness and low blood pressure needs to be examined by a doctor to find out the cause.
However, if this is your regular blood pressure, that is, whether you are dizzy or not, your blood pressure is similar, then your dizziness has nothing to do with blood pressure.
In addition, some medications used to control blood pressure such as Alpha blockers (controlling blood flow during stress can cause orthostatic hypotension when getting out of bed or rising from a sitting position). Due to the temporary hypotensive effect of the drug, dizziness occurs.
Dizziness and high blood pressure: Some diseases that occur when high blood pressure such as cardiovascular diseases, vestibular cochlear, ... can make patients feel dizzy. In addition, patients who have had a stroke due to high blood pressure will also have symptoms of dizziness.
As can be seen, the main association between dizziness and blood pressure is that uncontrolled blood pressure leads to dizziness along with other symptoms. Only a small number of cases of dizziness are caused by high or low blood pressure, while the majority are caused by other causes. Often cases involving dizziness and blood pressure are few and resolve quickly.
