Hypertension, which is among the most common chronic diseases in adults, is a major cause of stroke, heart disease, and renal failure. About one billion people live with hypertension worldwide, many of whom do not control their blood pressure well, despite the fact that lowering BP lessens the risk of renal and cardiovascular disease. One of the most effective ways of coping with hypertension is through self-management, making patients more responsible for their own care.
