Dizziness caused by high blood pressure should be measured standardly, in a sitting or lying position, and when changing position, it should be left for 3 minutes before measurement. If the usual blood pressure control is possible and this measurement is much higher than the usual blood pressure, dizziness is caused by excessive blood pressure, resulting in inadequate blood supply to the brain. It is necessary to lie down immediately and remove factors such as transient exertion and emotional excitement. If the blood pressure still continues to increase, it is necessary to temporarily take short-acting antihypertensive drugs such as captopril orally, plus rest, to gradually bring the blood pressure back to normal. If blood pressure control is usually unsatisfactory and dizziness occurs frequently, it is necessary to adjust the medication for hypertension, which can be combined with two antihypertensive drugs, as well as monitoring blood pressure and lifestyle adjustment, paying attention to salt reduction, fat reduction and less fried food. If you do not get dizzy, increase your exercise and lose weight, your blood pressure will stabilize and your dizziness will gradually disappear.
