Insufficient oxygen and blood supply to the head can be divided into physiological and pathological, physiological can be relieved after resting, and pathological is usually considered to be related to cerebral embolism, vertebral artery cervical spondylosis, blood pressure abnormality, etc., as follows:
1. Physiological: poor blood circulation caused by excessive mental tension and anxiety, sleep disorders, etc. can cause symptoms of cerebral ischemia and hypoxia such as dizziness and fatigue, which can be relieved by adjusting the mood, resting and relaxing.
2. Pathologic:
(1) Cerebral embolism: the thrombus dislodged from the heart, vascular plaque and other emboli block the cerebral blood vessels, manifested as headache, hemiparesis, and even coma and other symptoms, generally require cardiac monitoring, intravenous urokinase and other thrombolytic therapy, oral aspirin and other anti-platelet aggregation drugs, and in severe cases, if necessary, surgical treatment.
(2) Vertebral artery cervical spondylosis: caused by degenerative cervical spine disease, manifested by dizziness, nausea, tinnitus and other symptoms of cerebral ischemia and hypoxia, drug treatment includes mannitol to reduce cerebral edema, nimodipine and other calcium channel blockers to improve the cerebral circulation, eszopiclone and other sedative drugs, physical therapy, including heat therapy, ultrasound therapy, traction, and so on, and in severe cases, surgical treatment can be considered.
(3) Abnormal blood pressure: low blood pressure leads to insufficient cerebral perfusion can appear dizziness, blurred vision and other symptoms of cerebral ischemia and hypoxia, general physiological supplementation can be, if severe anemia caused by the need for blood transfusion; long-term hypertension can cause cerebral vascular ischemia, atherosclerosis, cerebral blood supply is insufficient, generally need to take omesartan, benedryl and other antihypertensive drugs.
If the patient has symptoms of cerebral hypoxia and blood supply insufficiency, it is recommended to go to the hospital, clarify the cause of the disease, and follow the doctor’s instructions for treatment.
