What causes high blood pressure and how?

Low blood pressure generally refers to diastolic blood pressure, high diastolic blood pressure may be due to improper diet, hyperlipidemia, coronary atherosclerotic heart disease and other reasons, the specific relief methods are as follows: 1. improper diet If the patient usually eats high sodium salt, high fat food, it is easy to lead to increased blood viscosity and high diastolic blood pressure. Patients should improve their poor eating habits, pay attention to maintaining a low-salt, low-fat diet, and pay attention to drinking plenty of water, which helps to dilute blood viscosity and relieve diastolic high blood pressure.2. Hyperlipidemia If the patient has hyperlipidemia, blood viscosity will also increase abnormally when blood lipid levels are too high, so diastolic blood pressure levels will also increase. Patients should follow the doctor's advice to use atorvastatin calcium tablets, rosuvastatin calcium tablets, simvastatin tablets and other drugs to help control blood lipid levels.3. Coronary atherosclerotic heart diseaseIf the patient has coronary atherosclerotic heart disease, when coronary artery narrowing gradually leads to blood flow obstruction, it usually causes diastolic blood pressure to rise. Patients should take more rest and follow the doctor's advice to use aspirin enteric-coated tablets, clopidogrel bisulfate tablets, warfarin sodium and other anticoagulant drugs to control the progression of the disease and improve the high diastolic blood pressure.
