Patients with hypertension do not necessarily need to take medication for treatment; improving lifestyle may be more important than taking medication. If the systolic blood pressure is 140-160 mmHg and diastolic blood pressure is about 80-90 mmHg, patients are advised to adjust their lifestyle by ensuring a low sodium diet, reducing weight, increasing exercise and developing regular habits. If the blood pressure is higher than 160/90mmHg for a long time, and combined with coronary heart disease, kidney disease, cerebrovascular disease, patients need to take medication for treatment, usually in the morning on an empty stomach.
