Taking high blood pressure medication every day that is normal one day and abnormal the next may be caused by conditions such as poor diet, stress, and excessive alcohol consumption. Hypertension refers to a condition in which the pressure of flowing blood against the walls of blood vessels is consistently higher than normal. Blood pressure can usually be controlled within the normal range by improving lifestyle and medication. If you take medication every day as prescribed by your doctor, but your blood pressure is normal today but abnormal tomorrow, it is usually caused by improper lifestyle, such as improper diet (excessive intake of high sodium diet), long-term mental stress (nervousness will lead to sympathetic nerve excitement in the body, which will raise the blood pressure), excessive alcohol consumption and so on. It is recommended that patients use medication under the guidance of a doctor and avoid taking it on their own. During the use of drugs also need to develop good habits, pay attention to life regulation. Diet to light, eat less high sodium food, maintain a good mood, avoid a lot of alcohol.
