Here's a breakdown of the stages of hypertension: Elevated Blood Pressure: Systolic (top number) 120-129 mmHg AND Diastolic (bottom number) less than 80 mmHg. Stage 1 Hypertension: Systolic 130-139 mmHg OR Diastolic 80-89 mmHg. Stage 2 Hypertension: Systolic 140 mmHg or higher OR Diastolic 90 mmHg or higher. Non-pharmacological treatment of hypertension focuses on lifestyle modifications to lower blood pressure, including adopting the DASH diet (high in fruits, vegetables, low-fat dairy), reducing daily sodium intake, achieving a healthy weight and engaging in moderate aerobic exercise. Other effective methods include limiting alcohol, quitting smoking, reducing stress through meditation/yoga, and increasing potassium intake.
