High blood pressure requires quitting smoking. Patients with high blood pressure need to control various risk factors that may lead to an increase in blood pressure, and smoking is one of the reasons that may lead to an increase in blood pressure. Tobacco contains more harmful substances. Long-term smoking can cause damage to the walls of the arterial blood vessels, resulting in atherosclerosis, a decrease in the elasticity of the blood vessels, which may lead to an increase in blood pressure levels. Patients with high blood pressure are prone to cardiovascular and cerebrovascular diseases. Smoking is also a risk factor for atherosclerosis, which can not only increase the risk of high blood pressure, but also increase the risk of cardiovascular and cerebrovascular diseases. Smoking is not only harmful to hypertension, but also to the respiratory tract, which can cause serious damage, and may lead to chronic obstructive pulmonary disease and lung cancer. Patients with high blood pressure must strictly quit smoking, low-salt diet, and take oral medication under the guidance of a physician.
