Insufficient blood supply to the brain can cause insufficient blood flow to the arteries in the ear, thus causing a high-pitched tinnitus sensation. Its treatment mainly focuses on the causes of tinnitus, such as improving blood microcirculation, stabilizing blood pressure and stabilizing blood lipids for medication. 1. Improvement of blood circulation: blood volume expanding drugs such as dextrose can be used. This drug can reduce platelet adhesion and increase plasma osmotic pressure, thus expanding blood volume, of which low molecular and small molecular dextrose has better effect on improving blood microcirculation. However, there may be adverse reactions such as allergy, fever and coagulation disorders during administration. 2. Stabilize blood pressure: you can eat a diet with less salt and low fat, and if you have high blood pressure, you should take medication on time, such as amlodipine, and pay attention to the adverse reactions such as redness, palpitation and abdominal pain after taking it. 3. Stabilization of blood fat: If there is an increase in blood fat, you can first adjust the diet, eat less animal fats, egg yolks and other foods, if you reach the standard of high blood fat, you can take drugs such as simvastatin orally. Reactions such as nausea, rash and indigestion may occur after taking simvastatin. It is recommended to take the medication under the professional guidance of a doctor to avoid wrong medication.
