5 frequently asked questions about high blood pressure

1.What state is blood pressure when sleeping？

Blood pressure decreases during sleep, and in normal people or people with hypertension, blood pressure values change in an arytenoid pattern. Blood pressure is at a high level during the day, and at night, especially during sleep, it drops and is at a lower level. This is mainly related to the excitability of the human-plant nervous system. At night, the vagus nerve tone increases, the sympathetic excitability decreases, the blood vessels are in a more relaxed state, and the blood pressure drops, which is a normal situation.

Such patients need to pay attention to the reasonable choice of drugs because the blood pressure is lower at night during sleep and higher during the day, the drug with longer effect should be selected. Early morning meditation, just after the effect of the drug to play the daytime high blood pressure down. At night, the blood pressure can still be maintained at a more appropriate level because the medication has been used for a longer period and the effect of the medication gradually diminishes.

Try to reduce the medication in the evening, especially the faster effect of antihypertensive drugs, which will cause the patient's blood pressure to fall further during sleep at night, down to an inappropriate level, and even cause cerebral thrombosis, myocardial infarction, etc.

2.Does blood pressure drop when a person doesn't eat?

Not eating can cause low blood pressure, but it is usually only people who do not eat for a long time that cause low blood pressure. If you don't eat for a long time, your body will lose weight, and if you don't have enough energy for a long time, the pressure in your blood vessels will drop, which is why people who don't eat for a long time have low blood pressure.

Long-term non-eating, the body's energy sources will be insufficient, insufficient energy sources will cause the body a series of activities to reduce, will cause the body's metabolic rate to reduce, will cause the gastrointestinal tract function to reduce, but also affect the normal work of the brain nerve center, because not eating leads to no source of sugar, the body glucose content is reduced, the brain work will be inhibited. If one or two meals are not eaten occasionally, blood pressure will not decrease, mainly because blood pressure is controlled by the central brain.

3.Why hypertension cannot be completely cured？

Hypertension is the most common chronic disease, through clinical medical investigation found that hypertension can not be completely cured, of course, as long as good prevention, good control of their blood pressure, can effectively reduce the method of hypertension, and effectively reduce mortality.

There are many reasons why hypertension cannot be completely cured. First of all, the cause of hypertension is not clear at present. That is to say when the cause is not clear, it is impossible to treat the disease completely, and there are some limitations in the process of treatment. The cause of hypertension is not completely clear, from the medical point of view, often more understand the cause of hypertension, such as mental work, long-term mental stress, improper diet, often drinking, or obesity, and of course, there is a family history of hypertension and so on. These are the causes of high blood pressure, but they are not the primary cause of the disease.

In addition, patients with hypertension are also prone to atherosclerosis, which is one of the most important reasons why hypertension is particularly harmful. High blood pressure can lead to atherosclerosis, and atherosclerosis, in turn, can promote further damage from high blood pressure. Medication for hypertension did not significantly promote the improvement of atherosclerosis. Long-term hypertension will lead to the thinning of blood vessel walls in patients, resulting in a sudden and significant increase in blood pressure, which further aggravates the symptoms of hypertension in patients. And high blood pressure is also easy to cause patients to appear heart failure, cause patients to appear brain artery disease, even cause paralysis and other conditions. Hypertension can only aggravate the disease, but can not be completely cured.

For patients with high blood pressure, of course, don't worry too much about, through the clinical investigation found that patients with high blood pressure at ordinary times as long as to strengthen the prevention and timing of antihypertensive medications regularly, keep good habits of life, they will be able to maintain blood pressure at a healthy level, so to minimize the harm of patients with high blood pressure will be. For patients with hypertension, the cause of this chronic disease has not been completely clear, especially from the gene level has not been completely conquered, in the future, it is expected to be clear on this level of the cause, and then hypertension may be completely cured.

4. Can driving cause high blood pressure?

The pathogenesis of hypertension has many mechanisms, one of which is prolonged driving and sedentary driving. So here to remind the drivers who often drive, pay more attention to their precautions, if hypertension is on the road in driving the consequences are unthinkable.

When driving a person's attention is highly concentrated, especially on the highway, continuous tension will stimulate sympathetic excitation, resulting in a rise in blood pressure, vascular spasm contraction reduced blood flow, and intensify myocardial ischemia and hypoxia. When the road is congested, people's emotions are easily irritable, encounter overtaking, violations, inevitably anger from the heart, a large influx of blood to the heart, blood pressure rose sharply, at this time, I am afraid that the morning to eat antihypertensive drugs can not suppress the rising blood pressure. In addition, after the car, many people completely dependent on the car, and even go out to buy a bag of salt are to drive and walk every day even more than 500 steps. In the long run, the legs enter a "wasted" state, prone to leg aging, more serious is the lower extremity blood flow back to the heart lack of power, the heart needs to spend more effort to complete the lower extremity blood circulation. Driving is because always keep a posture, blood flow is slow especially easy to long thrombosis. If thrombosis occurs in the veins of the lower extremities, once the thrombus is dislodged, it may cause a fatal pulmonary embolism.

What should hypertensive patients pay attention to driving? 

• First, drive long distances, try to shorten the continuous driving time, rest at least 10-15 minutes every two or three hours, and have timely hydration.

• Second, in poor road conditions, road congestion to avoid fire, you can sing and listen to soothing music. Singing loudly can enhance gas exchange and provide more oxygen to the heart and lungs. In places with severe traffic jams and poor air circulation, open the windows less often, as the harmful gases emitted from a large amount of exhaust may stimulate the blood vessels, causing vascular spasms and inducing heart disease. 

In addition, control the number of times you drive, it is best to drive no more than 3 days a week. If you experience dizziness and chest tightness while driving, stop the car in a safe are

5.What is the maximum blood pressure that can be reached?

There is no maximum value for hypertension. 

Everyone's blood pressure level is different and each level of hypertension manifests itself differently. Normal blood pressure is 90-140mmHg for high pressure and 60-90mmHg for low pressure. High pressure and low pressure can be diagnosed as hypertension as long as they are above this level. It is common to have a predominantly elevated high pressure, which can be over 200mmHg, or a predominantly elevated low pressure, which can be over 110mmHg.

Each person's ability to tolerate hypertension is also different. 

Some patients with a blood pressure of 140-150 mmHg feel very strong headaches and headaches, while some patients with a blood pressure of 180-200 mmHg do not feel it. The blood pressure of hypertension is only the performance and measurement value, and its sensation and clinical manifestations are also different.

Patients with a systolic blood pressure of 200 mmHg are more dangerous. 

Whether the blood pressure rises gradually or suddenly to 200 mmHg, are more dangerous conditions. Once the systolic blood pressure is greater than 180 mmHg, it can indicate that the patient has entered a dangerous state. According to the clinical manifestations, hypertension can be divided into hypertensive emergencies or hypertensive non-emergencies, hypertensive sub-emergencies. When the systolic blood pressure of hypertensive emergencies is usually greater than 180 mmHg, the patient may experience damage to the heart, brain, kidney, and other parenchymal organs, and may suffer from impaired consciousness, cerebral hemorrhage, cerebral infarction, acute heart failure, angina pectoris, and other conditions. Acute oliguria or a sharp decline in kidney function may also occur, and patients need emergency antihypertensive treatment under supervision. In addition, if the blood pressure suddenly rises above 200 mmHg without discomfort, which may not cause heart, brain, or kidney organ damage temporarily, the blood pressure should also be actively lowered and the antihypertensive drugs should be adjusted.
