Does hypertension need to reduce blood pressure ? 𝐁𝐥𝐨𝐨𝐝 𝐏𝐫𝐞𝐬𝐬𝐮𝐫𝐞 𝐅𝐀𝐐

Hypertension is very common in our daily life. Generally, symptoms such as dizziness, limb numbness, nocturia, palpitation, chest tightness, Fatigue and so on can be seen. Many patients can obviously relieve relevant symptoms after taking antihypertensive drugs. However, a considerable number of hypertension patients do not have any symptoms, which leads to a strange question: does hypertension need to reduce blood pressure? In order to help you solve your doubts, we will answer this question from the following three aspects: the nature of blood pressure, the harm of hypertension and the necessity of controlling blood pressure.

1. How does human blood pressure form?

Blood pressure is a basic vital sign and the most basic index to judge a person's health status. Blood pressure refers to the lateral pressure of blood on the vascular wall in the artery, because blood pressure was initially measured by mercury column, so the unit of mmHg is used, that is, the height of mercury column is used to represent the lateral pressure of blood on the vascular wall. The human heart has its own fist size. To some extent, the heart is more powerful than the fist. The Heart is a blood pump, which is also like a twisted towel, shrinking and relaxing constantly, loosen and tighten, pump the bleeding fluid into the aortic during contraction, the arterial vessels are full of elasticity, one part of the heart works to push the blood to the whole body, the other part forms the lateral pressure on the vascular wall, this part of pressure is named systolic pressure; After the heart contracts, it begins to relax, and the originally expanded arterial vessels are retracted elastically. At this time, the lateral pressure of blood to the vessel wall is diastolic pressure. For example, a person's blood pressure is 122/82mmHg, that is, the systolic pressure is 122mm Hg, and the diastolic pressure is 82mm Hg, which represents the pressure fluctuation of blood flow on blood vessel wall, it is a concentrated expression of cardiovascular function and is mainly affected by three factors: cardiac contraction force, peripheral vascular resistance and circulating blood volume.

2. What is hypertension? What harm is there?

Hypertension refers to the phenomenon that the pressure of flowing blood on the vascular wall is continuously higher than normal. The diagnostic criteria for hypertension in Chinese come from the hypertension guidelines of Yu Zhonghua Medical Association (CMA), which define hypertension with 140/90mmHg. Blood is pumped out from the heart, which is prevalent among limbs. The influence range of blood pressure is also from large blood vessels to microvessels and even every organ. High blood pressure will inevitably affect the normal function of cardiovascular and lung, brain, liver, kidney and other organs. Target organ damage of hypertension mainly includes heart failure, stroke, renal failure, etc. These diseases are very difficult clinically. If we can control blood pressure well so as to prevent slight progression, the prognosis will be greatly improved, this is the truth of "prevention before illness" mentioned by traditional Chinese medicine, and "prevention before illness" mentioned in "Huangdi Neijing" also emphasizes prevention.

3. The necessity of controlling blood pressure

The current situation of hypertension control in Chinese people is still not optimistic, and there are "three low" problems, namely low awareness rate, low treatment rate and low control rate. According to this situation, hypertension knowledge should be popularized by all people, actively control blood pressure to improve prognosis. In the daily outpatient service, some questions raised by some patients are answered here together.

Q: What should I do if I have hypertension?

A: First, see A doctor in time to clarify the cause of the disease, then take medicine regularly and monitor it regularly. At the same time, we should also straighten our mentality. The tension towards the disease can also aggravate hypertension, the fundamental goal of treating hypertension is to reduce the risk of target organ damage, and antihypertensive therapy can bring direct benefits,

Q: Is it called hypertension as long as blood pressure rises?

A: people's blood pressure fluctuates in different environments and different states. For example, in cold environments, blood pressure will rise beyond the normal range during emotional excitement and strenuous exercise. Most of these are physiological and transient, blood pressure can return to normal level when separated from cold environment or resting state. Clinically, the diagnosis of hypertension requires that the blood pressure measured in resting state is relatively accurate without taking antihypertensive drugs. At least three times of non-day blood pressure increase can be diagnosed.

Q: I have no feeling of hypertension. Can I not take medicine?

A: This problem is common. In the final analysis, patients know too little about hypertension. The fundamental purpose of taking medicine to control blood pressure is to reduce the risk of target organ damage, which can improve the prognosis, therefore, hypertension patients must take medicine regularly, whether there are symptoms or not.

Q: Why is blood pressure still not well controlled after taking medicine?

A: This involves A problem, that is, the severity of hypertension. According to the highest blood pressure value, hypertension can be classified into Grade 1, Grade 2 and grade 3. If the blood pressure has not been controlled to reach the standard, it may be because the curative effect of the existing drugs is limited, and the dosage can be appropriately added, or other kinds of antihypertensive drugs may be added to assist the antihypertensive. Of course, it may also be due to the problems of daily living habits, such as excessive salt intake in food, staying up too late and emotional factors can also lead to unsatisfactory blood pressure control. Therefore, in this case, it is suggested that patients go to the cardiovascular clinic to seek doctors to adjust the antihypertensive plan.

Q: Is it OK to just take traditional Chinese medicine to treat hypertension?

A: At present, the mainstream antihypertensive programs are still mainly Western medicine, with clear target and fair curative effect. However, the target of traditional Chinese medicine is too broad, and its antihypertensive effect is weak. The curative effect on people with different constitutions is different. Therefore, traditional Chinese medicine cannot be used only to treat hypertension, and Western medicine is mainly used clinically, traditional Chinese medicine can play a certain auxiliary role.
