Mild hypertension, also known as grade 1 hypertension, can be controlled by therapeutic lifestyle interventions without medication for the time being if there is no comorbidities such as diabetes or target organ damage. Hypertension requires the use of antihypertensive drugs: patients with hypertension grade 2 or above; patients with hypertension combined with diabetes mellitus or patients with target organ damage or complications such as heart, brain, kidney, etc.; patients with persistently elevated blood pressure who have not yet gained effective control of their blood pressure after improving their lifestyles; and high-risk and very high-risk patients who must be treated with antihypertensive drugs. Patients with mild hypertension can control their blood pressure without drugs through therapeutic lifestyle interventions such as reducing weight, reducing fat intake, increasing exercise, reducing sodium intake, quitting smoking and limiting alcohol consumption, etc. If the blood pressure is not well controlled in this way, the use of drugs to control blood pressure should be considered. Patients with mild hypertension should go to the hospital to lower their blood pressure under the guidance of a doctor to prevent complications.
