The national standard for normal blood pressure is <140/90mmHg, but it doesn't mean that blood pressure over this value must be hypertension! Blood pressure suddenly rises to 140/90mmHg, maybe you are normal! The values of the human body are never static, sometimes they rise, sometimes they fall, this transient change does not mean anything, just like the tachometer of a car, when we suddenly and vigorously step on the gas pedal, the value on the tachometer will quickly spike, but with subsequent smooth fueling, the tachometer will slowly fall and eventually level off, and the same is true for blood pressure. Blood pressure is the pressure exerted on our blood vessels by the internal blood. In the same size blood vessel, the blood circulating becomes more, and the pressure (blood pressure) will naturally increase. When a patient performs strenuous physical activity, the metabolism will speed up and the heart will beat faster, which means the heart is working hard, and at this time its consumption of blood oxygen will also become more. This means that the heart is working hard and consuming more oxygen. The patient should think about the cause of the increase in blood pressure! Before we discuss blood pressure lowering, we should first understand what the patient has done to cause the rise in blood pressure. If, as I said above, "physical activity is the reason for the rise in blood pressure," then the patient does not need to do anything, and resting in place for a while may lower the blood pressure. If it is caused by taking drugs indiscriminately, such as antidepressants, hormones, anti-inflammatory drugs, then you need to stop taking the relevant drugs. If the increase in blood pressure is due to a nerve disorder or blood vessel spasm caused by a recent poor rest or a major shock, then you should pay more attention to rest and adjust your mental state in time. If this blood pressure is measured several times and stabilized, then it needs to be controlled! Blood pressure is never measured once, it is measured many times and at many times. If the final result is still at 140/90mmHg, then the diagnosis of hypertension can be confirmed, but this value is at the lowest point, which is considered a relatively light stage, it is not recommended that patients take antihypertensive drugs, but should be controlled through the improvement of daily habits, dietary principles, this time is generally three months as the standard, three months after the blood pressure is not any improvement, or even higher, only then After three months, the blood pressure does not improve, or even higher, you need to choose antihypertensive drugs under the guidance of a professional physician, single or combined antihypertensive drugs.
