The need to take medication for sometimes high and sometimes normal blood pressure depends on the cause of the elevated blood pressure; if it is caused by physiological reasons, no medication is needed. If the cause is physiologic, no medication is needed. If Grade 1 hypertension can be improved by lifestyle, no medication is needed, while Grade 2 or higher hypertension requires medication. If the blood pressure is sometimes high and sometimes normal, it is most likely due to transient elevation of blood pressure caused by emotional factors or environmental factors, etc. This is a physiological cause and does not require medication, and the blood pressure will return to normal after removing the causative factors. However, if the blood pressure rises occasionally, which is classified as Grade 1 hypertension, it is often necessary to improve the lifestyle, low-salt and low-fat diet and participate in more physical exercise to control the blood pressure in the normal range. Some Grade 1 hypertensive patients whose blood pressure does not return to normal after lifestyle improvement, as well as Grade 2 and 3 hypertensive patients, need to take antihypertensive drugs, such as nifedipine and nilodipine. Patients with grade 2 or above hypertension need to take antihypertensive drugs regularly as prescribed by the doctor, and should not stop using them without authorization, otherwise it will also lead to high and low blood pressure, which is not conducive to blood pressure control. Patients must pay attention to the monitoring of daily blood pressure, if there is discomfort or abnormal blood pressure, you need to consult a doctor in a timely manner, cooperate with the doctor standardized treatment.
