Blood pressure is the force of blood against the walls of blood vessels (arteries) that carry blood away from your heart to other parts of your body. Consistently high blood pressure can lead to damage in the arteries and organs, and is a leading cause of stroke, heart disease and kidney disease. The reasons for developing high blood pressure are complex and can include lifestyle (e.g. diet and physical activity), genetic factors, and other medical conditions.
