Inadequate blood supply to the carotid arteries does not usually cause high blood pressure. Inadequate blood supply to the carotid arteries is usually not associated with high blood pressure. Causes of high blood pressure can be family history, stress, glomerulonephritis, aortic valve insufficiency, overweight and obesity. Carotid artery insufficiency is mostly caused by atherosclerosis, which may lead to insufficient blood supply to the brain, resulting in symptoms such as dizziness, fatigue, headache, tinnitus, etc., which may lead to stroke in severe cases, but in the vast majority of cases, it does not lead to an increase in blood pressure. If a patient is diagnosed with carotid artery insufficiency and has elevated blood pressure, it is recommended that the patient seek medical attention to determine the cause of the hypertension and inform the doctor of the history of carotid artery insufficiency, and to administer medication and other treatments under the doctor’s guidance.
