The original classification of hypertension
120-139/80-89 which are high values of normal blood pressure
140-159/90-99 belong to grade 1 hypertension.
160-179/100-109 belong to grade 2 hypertension.
Greater than 180/110, belongs to grade 3 hypertension.
So how do you calculate the blood pressure each time it is measured differently? To determine the classification of hypertension, it is not calculated according to the standard of blood pressure measured each time, it is the blood pressure measured without taking antihypertensive drugs, which is the classification of your own hypertension.
For example, when not taking medication, blood pressure 180/110mmHg, it belongs to grade 3 hypertension, but after taking antihypertensive medication, blood pressure dropped to 150/90mmHg, then this time is still calculated according to the original hypertension grade 3, just control down.
Before not taking medication, blood pressure measurement also has fluctuations how to count
For example, high pressure is a level, low pressure is a level, then according to which one to calculate? It should be calculated according to the higher one. Blood pressure 160/120mmHg, high pressure belongs to level 2, low pressure belongs to level 3, so how many levels is it? Because it should be calculated according to the higher one, so it should be grade 3 hypertension. Of course, there is no grade 3 hypertension now, it is called grade 2 hypertension.
What if the blood pressure is different twice in a row? In this case, it is recommended to take the average of the two times, with an interval of 5 minutes between the two times; if the difference between the two times is higher than 5mmHg, then measure 3 times and take the average.
What if the measurement at the hospital is not the same as the measurement at home?
Generally speaking, the standard for judging blood pressure measured in the hospital is 140/90mmHg, but the standard for measuring at home is ≥135/85mmHg to judge hypertension, and ≥135/85mmHg is equivalent to ≥140/90mmHg in the hospital.
Of course, if blood pressure fluctuations, a more accurate method is ambulatory blood pressure monitoring, that is, 24-hour monitoring of blood pressure, to see the specific blood pressure situation, ambulatory blood pressure average high pressure / low pressure 24h ≥ 130 / 80mmHg; or day ≥ 135 / 85mmHg; night ≥ 120 / 70mmHg. can be considered for the diagnosis of hypertension.
How to lower blood pressure
After hypertension is found, how to lower blood pressure, currently the only formal methods to lower blood pressure are healthy lifestyle and formal antihypertensive drugs when necessary.
For newly discovered grade 1 hypertension, that is, hypertension that does not exceed 160/100mmHg, you can first lower your blood pressure through a healthy lifestyle, low salt diet, high potassium diet, insist on exercise, do not stay up late, control weight, stay away from smoking and alcohol, reduce stress and so on are all conducive to blood pressure control.
If after 3 months, the blood pressure still has not dropped below 140/90, then we should consider lowering blood pressure together with antihypertensive drugs; or when high blood pressure is found, it is already above 160/100mmHg, or higher than 140/90mmHg, combined with diabetes or heart, brain and kidney disease, then you need to take antihypertensive drugs together to lower blood pressure as soon as possible.
As for the specific choice of which antihypertensive drug, or which kinds of antihypertensive drugs, must be taken under the guidance of a professional doctor, you can not just choose antihypertensive drugs.
Our goal is to have blood pressure lower than 140/90. For middle-aged people, especially young people under 45 years old, blood pressure should be lowered to below 120/80 as much as possible so that the risk of cardiovascular and cerebrovascular diseases will be lower.
In conclusion, the only way to effectively prevent various complications of hypertension is to monitor blood pressure well and to detect and control it early.
