Increased diastolic blood pressure is also hypertension. For adults, if blood pressure is measured on three consecutive non-same days, systolic blood pressure is greater than or equal to 140 mmHg and diastolic blood pressure is greater than or equal to 90 mmHg, hypertension can be diagnosed. If the systolic blood pressure is 140-159 mmHg and diastolic blood pressure is 90-99 mmHg, the patient is considered to have first-degree hypertension. Patients with first-degree hypertension can temporarily refrain from taking oral antihypertensive drugs and can adjust their lifestyle by improving their lifestyle, such as reducing weight, low salt and fat diet, quitting smoking and limiting alcohol, appropriately increasing exercise, reducing mental stress and holding a healthy mindset. If the systolic blood pressure is greater than 160 mmHg and diastolic blood pressure is greater than or equal to 100 mmHg, the patient is considered to have Grade 2 or higher hypertension, and it is recommended to go to a regular hospital for regular antihypertensive treatment and monitor blood pressure during the process of antihypertensive treatment.
