High blood pressure cannot be lowered by blood sampling, unless there is a one-time massive blood loss, such as a one-time blood loss of more than 800 ml, then there will be a reduction in blood pressure, but it is already in a state of possible shock, which is a very impractical idea. Therefore, patients with hypertension should mainly lower their blood pressure through standardized therapeutic lifestyle interventions and the application of antihypertensive drugs. People with high blood pressure should pay attention to weight control, quit smoking, limit alcohol intake, standardize moderate intensity exercise, and consume more potassium-rich fruits and vegetables, less salt and oil, and if necessary, choose antihypertensive drug therapy to lower blood pressure on the basis of lifestyle intervention.
