The reason why antihypertensive drugs cannot be stopped once taken is that most patients with hypertension require long-term medication to keep their blood pressure within the normal range, and once the medication is stopped there will be a sudden pulsating increase in blood pressure or an unstable blood pressure. However, there are some patients who can change their blood pressure through diet, exercise, and lifestyle changes. For example, patients should reduce weight, reduce sodium intake, supplement fresh vegetables and fruits, quit smoking and limit alcohol, adhere to regular aerobic exercise, reduce mental stress, and live a regular life with early to bed and early to rise, and under the effect of these good physiological factors, some patients can maintain their blood pressure within the normal range after stopping antihypertensive drugs.
