Hypertension is classified into 1-3 levels according to the level of blood pressure measurement, the higher the level, the higher the blood pressure is divided into two parts: high pressure for normal people is 90-140 mmHg, low pressure is 60-90 mmHg, hypertension level 3 means that the high pressure is already greater than 180 mmHg, low pressure is already greater than 110 mmHg, which is the highest level. In addition to grading by the level of blood pressure, sometimes the patient’s whole body condition is also taken into account to grade the risk. In some cases, although the blood pressure measurement is not too high, barely a level 1 blood pressure, the patient already has severe cardiac insufficiency, severe cerebrovascular disease or combined kidney disease. Since organ damage has already occurred, regardless of the blood pressure level, they are in the very high-risk group of hypertension and need to be actively treated. Some patients have a significant increase in blood pressure, but after examination, each organ and each organ has not been greatly affected. However, this group needs to be treated actively to lower blood pressure due to their high blood pressure level to avoid serious complications affecting the whole body organs.
