What is the reason for repeated increase in blood pressure?

As age increases, the incidence of hypertension will become higher and higher. Hypertension is very harmful to the human body. If you do not pay attention to regulating your blood pressure, it is easy to cause many complications. If you do not pay attention to regulating your blood pressure, it will cause blood pressure to rise repeatedly. In order to avoid serious harm to human health caused by high blood pressure, it is necessary to do a good job of prevention in normal times.

What is the reason for repeated high blood pressure?

Increased blood volume and increased cardiac output are the main causes of increased blood pressure.

If you pour more water into a bicycle tire that is already filled with water, the volume of the tire will increase. The water injected into the tube will exert pressure on the tube wall. Within a certain range, the more the tire is stretched, the greater the pressure. Our blood vessels are like rubber tires. If the amount of blood increases, the blood vessels will be further stretched, and the pressure on the blood vessel walls will increase, causing the arterial blood pressure to rise. But the effect of increased blood volume is more than that. It can also increase the amount of blood returning to the heart through the veins, increasing the amount of blood ejected when the heart contracts. The increased amount of blood returning to the heart can cause the heart rate to increase, and the combined effect of the two causes an increase in cardiac output. However, the reasons why the two pathways cause increased blood pressure are different. Increased ejection is equivalent to adding blood to the filled arteries, which further expands the blood vessels, increases the maximum value of the vascular pressure rise, and increases the systolic blood pressure; while the heart rate increases, the arterial blood discharge time during diastole decreases, which mainly affects the diastolic blood pressure, manifested as an increase in diastolic blood pressure.

The bad lifestyle habits that cause high blood pressure mainly include the following:

1. Age: The incidence rate tends to increase with age. Usually the elderly are a high-risk group for developing hypertension. Generally speaking, the elderly have a greater risk of developing hypertension. Many elderly people are very susceptible to the harm of hypertension, therefore, it is a factor closely related to hypertension, but hypertension has no age limit for the subject, but in the general population, for every 10 years increase in age, the relative risk of the incidence of hypertension increases.

2. Alcoholism: Drinking a little in moderation is good for the body and mind, but developing a habit of alcoholism can be very detrimental to physical health. Although drinking small amounts of alcohol will not cause high blood pressure. However, both systolic and diastolic blood pressure are related to the amount of alcohol consumed per day.

3. Salt: Excessive salt intake can lead to hypertension. How much you eat every day will directly affect your blood pressure. In daily life, improper diet can lead to high blood pressure, so we must be vigilant. Adhering to a scientific diet can help us stay away from high blood pressure. On the contrary, an unreasonable diet will put us at risk of falling into the abyss of high blood pressure. Eating too much salt can lead to high blood pressure. In addition, low intake of potassium and calcium, and insufficient intake of high-quality protein, are also believed to be factors that can increase blood pressure.

4. Obesity: More than half of patients with hypertension are obese to varying degrees, especially middle-aged and elderly people. According to research, for every increase in body mass index, the risk of developing high blood pressure within five years will increase by 9 percent. For every three-year increase in body mass index, the risk of developing hypertension within four years increases by 50 percent for men and 57 percent for women.

5. Heredity: About half of patients with hypertension have a family history of the disease. People with a family history of hypertension are much more likely to develop hypertension than normal people. According to clinical surveys, nearly 33% of hypertension is caused by genetic causes. If a family has a history of bad living habits, it is more likely to induce high blood pressure.

The frequent occurrence of hypertension in life can seriously harm people's physical and mental health. If you suffer from hypertension, you should think about timely diagnosis and treatment and not ignore the impact of the disease, but people should also pay attention to their lifestyle habits.
