Huazi chatted with many friends who have hypertension and found that many people have misunderstandings about blood pressure. Many people think that blood pressure below 140/90mmHg is normal blood pressure, and this value is also used as the target for lowering blood pressure when taking medicine. In fact, they misunderstood that normal blood pressure is not below 140/90mmHg.
Normal blood pressure is high pressure below 129mmHg, low pressure is below 84mmHg. The ideal blood pressure is a high pressure below 120mmHg and a low pressure below 80mmHg.
1. What is the "normal high value" of blood pressure?
The blood pressure indicator of 140/90mmHg that everyone is familiar with is the diagnostic standard for hypertension in my country. As long as the blood pressure measured three times on different days exceeds 140/90mmHg, it can be diagnosed as hypertension.
When the high pressure reaches 130~139mmHg, or when the low pressure reaches 85~89mmHg, , although it is not considered high blood pressure, it is not considered normal blood pressure, but the "normal high value" of blood pressure.
is at a normal high blood pressure, which is only one step away from hypertension. Although the medication standards have not yet been reached, blood pressure still needs to be actively controlled.
2. Non-drug control methods of blood pressure
People whose blood pressure is at a normal high value, as well as those who have been diagnosed with hypertension, need life intervention for blood pressure, which is a non-drug control method of blood pressure.
1, salt restriction : According to the latest hypertension treatment guidelines, the daily amount of salt should be limited to less than 5g. In related studies, reducing the daily intake of sodium ions by 1g can reduce systolic blood pressure (high pressure) by 6mmHg. But everyone should note that salt restriction does not mean completely eliminating salt, otherwise it may cause hyponatremia and affect health. A more reasonable daily amount of salt for is 3~5g.
2. Exercise : Carry out 150 to 300 minutes of moderate-intensity exercise every week. You can choose 5 days for exercise, 30 to 60 minutes each time, and perform resistance exercise (strength exercise) on the remaining 2 days. Continuing to exercise can reduce systolic blood pressure by 8mmHg.
3. Lose weight : Obese people with high blood pressure should lose weight so that their body mass index (BMI) is less than 24, and their waist circumference should be less than 90cm for men and less than 85cm for women. Losing 10Kg of weight can lower blood pressure by 5~20mmHg.
4, healthy diet : On the basis of not increasing the overall calorie intake, increasing the intake of vegetables, fruits, whole grains, beans, and dairy products, and reducing the intake of polished rice, refined noodles, and oils can reduce systolic blood pressure by 11mmHg .
5, alcohol restriction : Daily alcohol intake should not exceed 25g for men and 15g for women. People with high blood pressure should not drink alcohol . People with drinking habits can reduce their blood pressure by 3.31/2.04mmHg after limiting alcohol intake.
3. Blood pressure measured at home is more accurate than in the hospital
About one-third of people suffer from " white coat hypertension ". It refers to Some people will become nervous after seeing a doctor's white coat, causing the blood pressure measured in the hospital clinic to be higher . Therefore, for blood pressure measurement, home self-measurement values are more accurate than those obtained in hospitals.
Because it is more relaxing in the home environment, without taking antihypertensive drugs, when the blood pressure value measured by the home self-test reaches or exceeds 135/85mmHg, it can be diagnosed as hypertension , rather than using the application 140/90mmHg standard for hospital clinics.
4. Blood pressure control goals are lower than most people think
For people with high blood pressure, when undergoing antihypertensive treatment, keeping the blood pressure below 140/90mmHg is only the most basic goal. wants to better protect the kidneys , heart, brain and other important organs, the blood pressure control target should be lower . If you don't want cerebral hemorrhage , cerebral infarction , myocardial infarction, renal failure and other diseases to come to your doorstep, then you must be "strict" in controlling your blood pressure.
recommends that for hypertensive patients under the age of 65, the blood pressure reduction target is for high pressure to be less than 120mmHg and low pressure to be less than 80mmHg.
Elderly patients with hypertension who are over 65 years old have poor tolerance to lowering blood pressure and can gradually lower their blood pressure in gradients. First lower the blood pressure to 140/90mmHg, and then observe the adaptation for two weeks, then adjust the antihypertensive medication and continue to lower it to 130/80mmHg.
To summarize, the familiar blood pressure indicator of 140/90mmHg is the diagnostic value for hypertension. The ideal blood pressure is below 120/80mmHg, and the normal blood pressure is below 129/84mmHg. The ideal target for blood pressure control is less than 120/80mmHg, but for people over 65 years old, the blood pressure target can be relaxed to 130/80mmHg. The selection of antihypertensive drugs needs to be done under the guidance of a doctor. If you have any questions about medication, please consult your doctor or pharmacist.
