Blood Pressure Calculator

Normal blood pressure is below 120/80 mmHg. Elevated is 120-129/<80. Stage 1 hypertension is 130-139/80-89. Stage 2 is 140+/90+.

See a doctor if your BP is consistently above 130/80, if you get a reading above 180/120 (hypertensive crisis), or if you experience symptoms like severe headache or chest pain.

Regular exercise, reducing sodium intake, maintaining healthy weight, limiting alcohol, managing stress, and eating a DASH diet can all help lower blood pressure.
