What Are the Causes of Sudden High Blood Pressure?
Sudden changes in high blood pressure may or may not be cause for concern, depending on the cause and how long the change continues. In many instances, temporary rises in blood pressure that do not extend for more than a few hours or days are due to emotional or other reasons in the environment. However, if blood pressure remains high for a period of several weeks, a doctor may recommend substantial lifestyle changes in order to help reduce blood pressure measurements.
