If the high blood pressure in young people is secondary to hypertension, the normal range can be restored through exercise and proper diet. However, the cause of most hypertensive patients is not yet clear, and it is recommended to decide whether to give antihypertensive drugs based on the overall risk level of hypertension with improved lifestyle. Normal human blood pressure is between 90-140 mmHg for high pressure and 60-90 mmHg for low pressure. Nowadays, with the improvement of quality of life, hypertension is gradually becoming younger. Therefore, when the blood pressure value exceeds the above normal range on three non-same days of measurement, the diagnosis of hypertension and the classification of blood pressure should first be established by a professional physician, followed by an assessment of the patient’s cardiovascular and cerebrovascular risk factors and then treatment. For patients with mild hypertension, non-pharmacological treatment should be emphasized, and blood pressure should be actively monitored, and urine routine and other related tests should be reviewed regularly. In case of serious complications, prompt medical attention is required. Lifestyle interventions are reasonable and effective treatment for any hypertensive patient at any time, with the primary goal of reducing the overall risk of cardiac, renal and vascular complications and death. Therefore, it is recommended that all patients with hypertension should self-manage to prevent and treat hypertension.
