The carotid artery is one of the important components of the human body, and the main job of this part is to provide blood to the brain.
It is understood that from the definition point of view, the carotid artery can be divided into left carotid artery and right carotid artery, they have a fork in the part of the connection with the brain, if the part is obstructed, then it is easy to form atherosclerosis, and then form a plaque accumulation, so that the blood supply in the body is affected, and cause the problem of arterial stenosis.
This is a very serious cerebrovascular disease, but due to the lack of understanding of it in most patients;
Therefore, it is difficult to detect the disease in the first time and treat it, so that the condition worsens, causing harm to the patient's physical health, and causing the following problems.
First, the blood supply to the brain is insufficient
When patients suffer from this disease, atherosclerotic plaques will occur at the carotid artery site, which will narrow the blood vessels and greatly reduce blood flow, so that blood cannot enter the brain in time, which will lead to the problem of insufficient blood supply to the brain.
In the long run, once the blood supply to the brain is less than the blood required for basic brain activities, then the oxygen inside the brain will be undersupplied, and there will be a shortage of nutrients in the brain;
As a result, the patient has a series of uncomfortable symptoms, such as dizziness, tinnitus and memory loss, and if it is severe, it will also cause the patient to have stiff limbs, speech difficulties and other manifestations.
Second, cognitive decline
Not only that, but as carotid artery stenosis becomes more severe, the patient's cognitive ability will also decline.
Compared with ordinary people, patients with carotid artery stenosis will have different degrees of weakening of their ability to learn, remember and exercise.
If the patient cannot treat it in time, then the patient's daily life will be seriously harmed. Therefore, patients should pay special attention to it in normal times.
3. Ischemic lesions of the eye
Because the carotid arteries also supply blood to the eye while supplying blood to the brain, when a patient suffers from carotid artery stenosis disease, the eye will also have some abnormalities due to insufficient blood supply, such as ischemic lesions in the eye.
The main manifestation of this problem is vision loss, patients often feel that the eyes are very sore, and in severe cases, it will also lead to transient vision loss and visual field defects.
4. Cerebral infarction
In addition, as the case of carotid atherosclerosis becomes more and more serious, these plaques will gradually fall off;
The plaque that falls off can form a blood clot at the carotid artery, hindering the blood vessels in the brain and eventually causing cerebral infarction, which happens to be one of the main causes of stroke.
Therefore, patients with carotid artery stenosis are much more likely to develop brain obstruction and stroke than other patients.
Not only that, in addition to stroke, some patients may also have problems such as hemiplegia, and if they are severe, they may even be life-threatening.
These are the four main hazards caused by carotid artery stenosis. It can be seen that carotid artery stenosis will cause great harm to the human body, and patients should not only detect this disease in time, but also prevent it in advance to reduce the probability of disease.
Specifically, patients should try to maintain a good diet and living habits, do not fish and meat, and do not stay up late, so as not to cause unnecessary stimulation to blood vessels.
In addition, patients should strengthen daily exercise, promote metabolism, and better maintain the patency of blood vessels, thereby preventing the occurrence of diseases.
Once it is found that the patient has some abnormal phenomena, such as inexplicable headaches, dizziness, etc., then it is necessary to go to the hospital in time to receive examination and treatment, so as not to miss the best treatment time.
