Hypertension is the medical term used to describe high blood pressure. Blood pressure is the force of the blood pumped from the heart against the blood vessels. This force makes blood flow possible, delivering nutrients and oxygen to organs and tissues throughout the body. Hypertension occurs when there is too much pressure in your blood vessels. This may damage your blood vessels and cause health problems. Hypertension may lead to heart disease, stroke, kidney disease and dementia. Schedule an appointment to see your family doctor if you’re concerned you have hypertension.
