For those whose high blood pressure is serious enough to require medication, it is important to remember that changes in diet and lifestyle are also absolutely necessary. No single “wonder” drug or large amount of medication will help a person reduce his or her blood pressure to a healthy level—how one eats and lives will need to be improved as well. In fact, it has been shown that only 40 to 50 percent of people who rely solely on medication to reduce their blood pressure to normal levels are successful.
