Causes of high blood pressure include physiological and pathological, and pathological causes include atherosclerosis, hyperlipidemia, renal artery stenosis, etc. It is necessary to clarify the causes of the disease and then carry out general treatment and drug treatment. 1. Physiological: prolonged late night, high salt diet, smoking, nervous and anxious state and other factors will cause the sympathetic nervous tension and excitement to rise, which will cause temporary diastolic blood pressure rise, you can improve the symptoms through sufficient rest, light diet, quit smoking and drinking, avoid nervousness and anxiety and so on. 2.Pathologic (1) Atherosclerosis may cause the elasticity of the blood vessel wall to weaken, so that the blood vessel is not easy to contract and diastole, resulting in high diastolic blood pressure, you can take aspirin, clopidogrel and other drugs to reduce blood pressure. (2) Hyperlipidemia is due to the increase in blood viscosity, increase the peripheral resistance of blood vessels caused by the rise in diastolic blood pressure, it is recommended to take atorvastatin and other drugs to reduce blood lipids. (3) Renal artery stenosis can cause an increase in peripheral vascular resistance, which leads to an increase in low blood pressure, and the stenotic vessels can be improved through surgical intervention. Due to the diversity of causes, it is recommended to actively go to the hospital to find out the cause of low pressure, under the advice of the doctor to receive standardized treatment, drugs need to be used in accordance with the doctor’s instructions, the emergence of adverse reactions recommended to consult the doctor, drug allergy is prohibited.
