Second, it has a certain relationship with living habits. For example, smoking, drinking, not liking sports, eating, but also like to eat very salty or eating a fat diet or high sugar diet. In this case, poor weight control will also lead to high blood pressure. Third, environmental factors, such as long-term anxiety or nervousness, may also lead to increased blood pressure. Fourth, some patients may be taking some other drugs. For example, some contraceptives may also lead to increased blood pressure.
