Blood pressure is the force of blood pushing against the walls of your arteries. It's measured as systolic (top number) over diastolic (bottom number) pressure.
Systolic pressure (top number) measures pressure when your heart beats. Diastolic pressure (bottom number) measures pressure when your heart rests between beats.
Normal blood pressure is typically less than 120/80 mmHg. Elevated is 120-129/<80, Stage 1 hypertension is 130-139/80-89, and Stage 2 is 140+/90+.
