Hypertension or high blood pressure has a high risk factor for cardiovascular complications. In general, diuretics are preferred as a treatment for hypertension as it considerably helps to control the pressure and also proves less expensive. While a majority of the cases are termed as primary, only about 5-10% cases are classified as those suffering from secondary hypertension. A significant change in lifestyle can help to reduce hypertension to some extent. The average cost of treating hypertension is $50 per year.
