Mild carotid artery sclerosis is not serious, but if it is allowed to develop there are also causes of carotid artery sclerosis, such as hypertension, hyperlipidemia, smoking and abnormal lipid metabolism caused by diabetes. This condition may accelerate the development of carotid artery sclerosis, resulting in narrowing or occlusion of the blood vessels within a short period of time, which is more serious and may directly endanger the brain, leading to transient ischemic attacks, transient dizziness, syncope, blackouts or large cerebral infarction. Patients with hypertension and hyperlipidemia should strictly control and monitor their blood pressure and blood lipids to prevent further aggravation of carotid atherosclerosis and to prevent the disease from developing significantly in the future.
