High pressure, 150. Low pressure, 120. Is that serious?

High pressure of 150mmHg and low pressure of 120mmHg, i.e. blood pressure of 150/120mmHg. If you are in this blood pressure state for a long period of time, it is considered to be grade 3 hypertension, which is more serious and should be treated immediately.
Long-term severe hypertension will damage the heart and blood vessels, making it easy to develop hypertensive heart disease, cerebral hemorrhage, chronic renal failure, and retinopathy. In order to reduce the probability of cardiovascular and cerebrovascular diseases caused by hypertension, antihypertensive treatment should generally be administered.
The use of antihypertensive treatment should take the principles of small dosage, giving priority to the choice of long-acting preparations, combined use of drugs, individualization, and the treatment of hypertension should be balanced with the control of blood glucose, blood lipids, uric acid and so on. Meanwhile, for the elderly, patients with a long course of disease or hypertension with complications, the rate of blood pressure reduction should be moderately slow.
If there is any abnormality in blood pressure, standardized antihypertensive treatment should be carried out under the guidance of the doctor, and do not blindly take antihypertensive drugs on your own.
