The criteria for confirming the diagnosis of hypertension is a blood pressure value of more than 140/90 mmHg measured on three or more occasions at rest at different times of the day on a non-medicated condition. When a young person’s systolic or diastolic blood pressure reaches 140 mmHg, it is an abnormal condition, but it is not directly diagnosed as hypertension. If the systolic or diastolic blood pressure is 140mmHg occasionally, it is not diagnosed as hypertension and can be caused by severe mood swings, strenuous exercise, etc. The occurrence of such hypertension is generally of a transient nature, without serious symptoms, and can usually be improved by psychological intervention and rest, and is not true hypertension. If it is a long-term monitoring of blood pressure are 140mmHg, then it is hypertension, should promptly seek medical attention. If it is systolic blood pressure 140mmHg, it is not too serious, and the symptoms are not obvious when you can first control blood pressure by improving bad habits, such as controlling diet, active exercise, regular rest and other ways. If the diastolic blood pressure is 140mmHg, it is more serious and may cause target organ damage or even life-threatening. Treatment with medications such as diuretics, calcium antagonists, angiotensin-converting enzyme inhibitors, etc., should be used under medical supervision. When other complications occur, treatment should also be actively carried out to avoid aggravation of the disease.
