When blood flows in the blood vessels, it can produce a certain amount of pressure on the walls of the blood vessels, which can promote the flow of blood in the blood vessels, and this dynamic is called blood pressure. It is only due to some factors that stimulate, many people will have an increase in blood pressure, this phenomenon is called high blood pressure.
Once the blood pressure is high, it will cause people to feel dizzy or headache. It's just that there are many people with high blood pressure whose blood pressure values are in a stable state in their daily lives, but there will still be repeated dizziness, what is going on?
Why do I still feel dizzy with normal blood pressure?
First, dietary factors
For people with high blood pressure, there are many reasons why blood pressure is at a normal level and still dizziness occurs, especially when there is no adjustment of eating habits, it is very likely that this condition will occur.
If you eat too much meat food every day, or sweets, and spicy foods, it will cause the blood flow rate to become slower. Blood vessels are also stimulated as a result, most likely causing spasms. Then even if the blood pressure value does not change significantly, it will cause the patient to have repeated dizziness or headaches.
Second, the drinking factor
There are many patients with high blood pressure who like to drink, because alcohol has the effect of dilating blood vessels and accelerating blood flow rate, so after drinking alcohol for a period of time, the blood pressure value of hypertensive patients will not rise, and there will be a decline.
However, in the process of decreasing blood pressure, there will be a phenomenon of low perfusion of the brain, which will cause a series of abnormalities such as dizziness, headache or nausea.
In addition, if the blood pressure value of the hypertensive population does not rise, but there will still be repeated dizziness, usually due to insufficient cerebral blood supply.
What is cerebral insufficiency?
1. Definition of disease
Insufficient blood supply to the brain is a phenomenon caused by a disorder in the circulation of the cerebral arteries, resulting in a decrease in the amount of blood flowing to the cerebral arteries. For healthy people, every 100 grams of brain tissue requires about 40 to 60 milliliters of arterial blood support per minute.
Once the blood supply to the cerebral arteries is lower than the normal demand, it will cause insufficient blood supply and oxygen supply to the brain, resulting in a series of uncomfortable symptoms. There are many reasons for cerebral blood supply deficiency, in addition to cervical spondylosis, heart disease, diabetes, hyperlipidemia, hypertension people also have insufficient cerebral blood supply phenomenon.
2. Symptoms of the disease
For people with insufficient cerebral blood supply, due to insufficient blood supply and oxygen supply to the cerebral arteries, people will have repeated dizziness, dizziness and headache problems, and will also be accompanied by easy to yawn during the day, drowsiness, excessive fatigue, as well as sleep disorders at night, easy to anxiety, depression, difficulty concentrating and other problems.
In addition, insufficient blood supply to the brain will cause some nerve functions to be abnormal, which will make people's hands and feet and faces appear numb or stiff and weak. If the optic nerve is compressed, it will cause people to have decreased vision, blurred vision, and even sudden and transient blindness.
All in all, for people with high blood pressure, if the blood pressure value is in the normal range, but dizziness will still occur, it is generally related to poor diet and drinking factors. In addition, if people with hypertension suffer from insufficient cerebral blood supply, they will repeatedly appear a series of abnormal symptoms such as dizziness, headache, and vision loss in daily life.
So when these symptoms appear, it is necessary to quickly go to the hospital for a series of tests. Under the guidance of a doctor, give corresponding treatment, and adjust the habits of diet, mentality, work and rest, etc., in order to maximize the improvement of dizziness and achieve the effect of maintaining their own health.
