Buzzing in the head of the elderly may be caused by atherosclerosis, which generally occurs in middle-aged and elderly patients, most of whom have a history of hyperlipidemia, diabetes and hypertension, and can be treated with oral Cipro, Ginkgo biloba drops and vitamin E to soften blood vessels and improve blood circulation, as well as oral glutathione, while controlling the patient’s blood lipids, blood sugar and blood pressure. When blood pressure is elevated, levamlodipine and amlodipine besylate can be taken orally. If blood sugar is elevated, metformin can be used to lower sugar, and if the effect is not good, byproterenol and repaglinide can be added at the same time, and insulin can be used to lower sugar if necessary. In case of elevated blood lipids, oral statins are usually taken, commonly used are simvastatin, resulvastatin and atorvastatin. If the patient has the above risk factors, oral aspirin can also be administered if necessary for anti-platelet aggregation therapy to prevent the patient from cerebral infarction.
