Generally speaking, the normal value of blood pressure for adults is 90-139 mmHg systolic and 60-89 mmHg diastolic, while a blood pressure of 142/92 mmHg is considered as hypertension, and the need for antihypertensive medication should be determined on a case-by-case basis. If the systolic blood pressure ≥ 140mmHg or diastolic blood pressure ≥ 90mmHg persists at the time of blood pressure monitoring, and life diet adjustment is ineffective, this condition generally requires the application of drugs for control. Initial diagnosis can also choose to measure with a 24-hour blood pressure monitor, which will be more accurate. Treatment is required according to medical advice, and common antihypertensive drugs include amlodipine and irbesartan. In addition, in the case of strenuous exercise, emotional excitement, stress, frequent late nights, smoking, drinking and irregular diet can also lead to an increase in blood pressure, which can be measured at the same time for 3 consecutive days. If it returns to normal and blood pressure keeps systolic pressure <140mmHg and diastolic pressure <90mmHg, you can observe it first, by adjusting your diet, such as a healthy diet with low salt, low fat and low calories, eating more vegetables and fruits, keeping a stable mind, exercising in moderation and ensuring sleep, etc. If blood pressure drops below 140/90mmHg, there is no need to take antihypertensive drugs and maintain good work and rest If your blood pressure drops below 140/90mmHg, you do not need to take antihypertensive medication, but maintain good work and rest habits, and monitor the changes in blood pressure regularly.
