Hypertension is the official term for high blood pressure. Blood pressure is the force of the blood as it pushes against the walls of your blood vessels. Chronically higher-than-normal blood pressure can raise risk for heart disease, stroke, and other health concerns.
Hypertension, or high blood pressure, is a chronic condition. Blood pressure can increase because there is too much volume in your blood vessels, which increases the force against them, or because there is not enough elasticity in your blood vessel walls, which increases the pounding against them and increases blood pressure.
