Low blood pressure generally refers to diastolic blood pressure, which can be regulated through lifestyle and taking antihypertensive drugs. 1. Lifestyle: If the diastolic blood pressure is mildly elevated, it can be regulated by reducing weight, supplementing fresh vegetables and fruits, reducing fat intake, quitting smoking and restricting alcohol, increasing aerobic exercise, and reducing mental stress. 2. Taking antihypertensive drugs: If patients with high diastolic blood pressure are unable to control their blood pressure through non-pharmacological treatments and have obvious symptoms such as headache and dizziness, they can take drugs such as nifedipine and hydrochlorothiazide according to the doctor’s recommendation to control their blood pressure. If patients with high diastolic blood pressure develop serious symptoms, they should go to the hospital in time to check the possibility of organic diseases and follow the doctor’s instructions to take effective treatment.
