The causes of sudden high blood pressure include physiological factors and pathological factors, of which pathological factors such as primary or secondary hypertension need to be treated with medications such as propranolol, amlodipine and other medications as prescribed by the doctor, and surgical treatment if necessary. 1. For people whose blood pressure is within the normal range, the sudden appearance of high blood pressure may be caused by emotional excitement or strenuous exercise, which is a physiological situation, and the blood pressure can return to normal after resting or calming down for a period of time, and usually does not need treatment. 2. The treatment of essential hypertension mainly includes general treatment and medication, of which the general treatment includes weight reduction, lowering the intake of sodium in food and moderate exercise. For patients with second-degree hypertension and above or hypertension combined with diabetes mellitus, medication is usually given, such as diuretics such as hydrochlorothiazide, β-receptor antagonists such as propranolol, and calcium channel blockers such as amlodipine. 3. If the increase in blood pressure is caused by aldosterone adenoma, it is usually possible to remove the adenoma through surgery to achieve the purpose of relieving clinical symptoms; and if the increase in blood pressure is caused by pheochromocytoma, it is also treated through surgical removal. Therefore, if you find a sudden increase in blood pressure, it is recommended to go to the hospital as soon as possible for a clear diagnosis and standardized treatment under the guidance of the doctor.
