With the rapid development of society and economy, the incidence of hypertension has been increasing year by year. Statistics show that the number of hypertensive patients in my country has reached 130 million, which is one-tenth of the total population of the country. Hypertension is hereditary, and more than 60% of hypertensive patients have a family history of hypertension. At present, medical science believes that the heredity of hypertension is determined by polygenic genetic factors. Therefore, people with parents with hypertension should pay special attention to preventing hypertension and develop healthy living and eating habits in daily life.
The dangers of high blood pressure
High blood pressure can seriously damage the functions of multiple organs in the body. High blood pressure can cause heart problems such as coronary heart disease, arrhythmia, myocardial infarction and angina pectoris. Hypertension can cause cerebral thrombosis, cerebral hemorrhage, cerebral infarction and insufficient blood supply to the brain. Hypertension can seriously threaten kidney health, increasing the probability of nephritis, proteinuria, and chronic renal failure. The eyes are also affected by high blood pressure. In mild cases, vision loss and fundus bleeding may occur. In severe cases, cataracts and even blindness may occur. Hypertension threatens the functions of multiple organs. In severe cases, it can cause multiple organ failures and cause death.
Factors that induce hypertension
(1) Mental and environmental factors
In addition to genetic factors, most of the causes of hypertension are acquired factors, among which mental and environmental factors have a direct impact on hypertension. If the human body is in a state of anxiety, irritability and mental stress for a long time, it is easy to cause high blood pressure. In addition, people’s living environment is also closely related to high blood pressure. Long-term living in an environment with loud noise and more visual stimulation may induce high blood pressure.
(2) Age factor
Under normal circumstances, high blood pressure occurs mostly in middle-aged and elderly people. Survey data shows that, at present, the incidence of hypertension in my country is related to people’s age. With age, the incidence of hypertension will also show an upward trend. Among them, people over forty years of age are more likely to suffer from hypertension.
(3) Living and eating habits factors
The stability of the body’s internal environment is related to high blood pressure. Frequent staying up late will cause the human body to be in an unstable state, which can easily lead to high blood pressure. In addition, long-term smoking and alcohol abuse will also speed up arteriosclerosis and eventually induce hypertension. People’s eating habits are also closely related to high blood pressure. Irrational dietary structure and excessive intake of saturated fatty acids may induce hypertension.
(4) Drug factors
The occurrence of hypertension is affected by many factors, including commonly used drugs. Some drugs can directly increase blood pressure, such as anti-inflammatory and analgesic drugs, hormone drugs, and contraceptives.
Symptoms of high blood pressure
According to the etiology of hypertension and the progression of its onset, hypertension can be divided into slow-onset hypertension and acute hypertension, and the symptoms of the two are different. Among them, chronic hypertension is more common in life.
(1) Progressive hypertension
There are basically no obvious symptoms in the early stage of progressive hypertension. Patients will only experience some typical symptoms after overwork and emotional agitation, such as headache, dizziness, fatigue, vertigo, insomnia, tinnitus, and inability to concentrate. This is usually due to advanced mental dysfunction. The early symptoms of patients with progressive hypertension are only a temporary rise in blood pressure, but as the disease progresses, the patient’s blood pressure will continue to rise, affecting other organs of the body. When the blood pressure rises suddenly, the patient will experience severe visual disturbance, severe headache, nausea, vomiting, convulsions, coma, aphasia and even hemiplegia. In the early stage, the symptoms of chronic hypertension are not obvious in the heart, but as the disease progresses in the later stage, patients will develop arrhythmia and even heart failure.
(2) Acute hypertension
Acute hypertension tends to occur in people between 30 and 40 years old. The symptom of acute hypertension is a significant increase in blood pressure. The patient’s diastolic blood pressure exceeds 17.3kPa (130mmHg). With physical discomfort such as polyuria, thirst and fatigue, the patient will experience retinal hemorrhage and exudation in the fundus of the eye, and the vision will rapidly decrease . Patients with acute hypertension will have symptoms of proteinuria, their kidney function will be affected, and symptoms such as hematuria and heart failure will appear. The course of acute hypertension develops quickly, and in severe cases it can induce uremia and even lead to death. If people have frequent severe headaches accompanied by vomiting, nausea and other symptoms, they must be vigilant, which is likely a sign of acute hypertension. In addition, dizziness is also one of the typical symptoms of acute hypertension.
Hypertension is one of the common diseases, which will directly affect people’s normal work and life, and seriously threaten human health and life safety. People should fully understand the predisposing factors and symptoms of hypertension, and achieve early prevention, early detection and early treatment.
