A low pressure of 105 mmHg and a high pressure of 140 mmHg, this condition already constitutes secondary hypertension. It has to be combined with the presence of other risk factors, such as high blood lipids, diabetes, obesity, etc. If there are risk factors present in this area, secondary hypertension is still a very serious condition. If there is no other risk factors, the blood pressure can be controlled through diet to keep it as stable as possible. If the diet is not good, the blood pressure can be controlled by medication. If the combination of some risk factors, we should take oral antihypertensive drugs directly to control the blood pressure within 138mmHg. Therefore, whether the current blood pressure is serious or not, it is necessary to take into account the individual’s condition and whether there are other risk factors to make a comprehensive judgment.
