Blood pressure range for stage 1 hypertension Systolic blood pressure is between 140-159 mmHg Diastolic blood pressure is between 90-99 mmHg It is recommended that stage 1 hypertension is mild hypertension. For asymptomatic patients, it is recommended to first control blood pressure by intervening in diet, exercise, and lifestyle habits. The diet of these patients is recommended to follow the principles of low salt, low fat, low sugar, high protein diet, less animal offal, fatty meat and preserved products, and more fresh vegetables and fruits. At the same time, pay attention to the combination of work and rest, keep enough sleep, and increase physical work and physical exercise appropriately. Patients with obesity should control the amount of food and total calories, reduce body weight, and stop smoking and limit alcohol consumption. In addition, patients should avoid staying up late and exerting themselves, keep their mood happy, and perform 24-hour ambulatory blood pressure monitoring or home blood pressure monitoring, and go to the hospital promptly when abnormal blood pressure is detected. If the blood pressure does not reach the standard after lifestyle interventions, the blood pressure should be treated with antihypertensive drugs under the guidance of a doctor so that the blood pressure can be maintained at or near the normal level. Maintaining normal blood pressure is useful in reducing symptoms, delaying the progression of the disease and preventing complications such as cerebrovascular accidents, heart failure and renal impairment. Thiazide diuretics, ACEIs, ARBs, CCBs, and beta-blockers can be used as initial therapy. The physician will choose initial monotherapy or combination of drugs based on the patient’s blood pressure and cardiovascular risk. If a strong indication exists, the drug will be administered for the indication. Specific dosing principles will be based on the clinician’s recommendation in an interview.
