Blood pressure may decrease after quitting smoking compared to before quitting, but this varies from person to person. Patients also need to assist in controlling their blood pressure by exercising more, reducing salt intake, and taking antihypertensive medications under the direction of a physician if necessary. The lifestyle of hypertensive patients has a great impact on their blood pressure, and one of the most important items in the treatment of hypertension is the recommendation to quit smoking. Because tobacco contains nicotine and other ingredients, which will excite the sympathetic nerve and central nervous system to cause vasoconstriction, blood pressure will rise. Therefore, quitting smoking is conducive to stabilizing blood pressure, and also helps to reduce the incidence of cardiovascular and cerebrovascular diseases. It is generally believed that, for patients with essential hypertension, there is hope that blood pressure can be lowered by 5-10mmHg after quitting smoking. In addition, in addition to smoking cessation, hypertensive patients should also limit alcohol consumption, reduce salt intake, less than six grams per person per day is recommended, and to low-fat diet, eat more fresh fruits and vegetables. It is also necessary to control weight and strengthen exercise, all of which can help reduce blood pressure. Of course, for patients who cannot achieve ideal blood pressure by adjusting their lifestyle habits, it is recommended to consult a specialist to find out the cause and take antihypertensive medication under the guidance of a doctor if necessary.
