Hypertension refers to a disease characterized by increased diastolic blood pressure and systolic blood pressure, and it is also a relatively common disease. Hypertension, also known as elevated blood pressure, is a phenomenon that the pressure on the blood vessel wall continues to rise when blood flows in the blood vessel. Hypertension is the main risk factor of cardiovascular and cerebrovascular diseases, and the mortality rate of complications such as myocardial infarction, heart failure and chronic kidney disease is relatively high.

Hypertension is a disease that can be prevented and controlled, which can reduce the blood pressure level of patients and obviously reduce complications such as heart disease and stroke. If the patient's illness is mild, it can be improved by adjusting diet and moderate exercise. It is necessary to pay attention to a low-salt and low-fat diet in diet, and usually take appropriate exercise to control personal weight.

The early symptoms of hypertension are not particularly obvious. Some patients may have headache or dizziness, and the symptoms will be relieved after rest. If the patient has symptoms such as headache, inattention, memory loss, numbness of limbs, nocturia and general fatigue, it is necessary to measure blood pressure in time, and the diagnosis of hypertension can be established by measuring blood pressure.

Normal blood pressure of adults is 90- 140mmHg, systolic blood pressure is 90-140mmH, and diastolic blood pressure is 60-90mmHg. When the patient's blood pressure exceeds normal, it will be diagnosed as hypertension, and when the blood pressure is lower than normal, it will be diagnosed as hypotension. Normal blood pressure means that the blood circulation of the body is unimpeded, and blood pressure can maintain normal operation under the regulation of various organs of the body, which can provide sufficient nutrients for the organs of the body.
