Blood pressure is a vital indicator of cardiovascular health. It's measured as two numbers: systolic and diastolic pressure.
Systolic Pressure: The top number, representing the pressure in your arteries when your heart beats.
Diastolic Pressure: The bottom number, representing the pressure in your arteries when your heart rests between beats.
Both your age and your blood pressure readings contribute significantly to your overall cardiovascular risk. As people age, their arteries can stiffen, which can naturally lead to slightly higher blood pressure. However, persistently high blood pressure (hypertension) significantly increases the risk of serious health problems like heart disease, stroke, kidney failure, and vision loss.
How This Calculator Works (Simplified Model)
This calculator uses a simplified model to estimate a *general risk factor* based on common guidelines and the interplay between age and blood pressure readings. It is important to understand that this is NOT a substitute for professional medical advice.
The calculation assigns a base risk score. This score is then modified by your age and blood pressure readings. Generally:
Higher systolic and diastolic numbers contribute to a higher risk.
Advancing age is associated with a naturally increased risk.

Always consult with a qualified healthcare professional for any health concerns or before making any decisions related to your health or treatment.
Interpreting Your Risk Factor (General Guidelines):
The output of this calculator is a conceptual "risk factor" score. While not a formal medical diagnosis, it can give you a general idea:
Low Risk Factor (e.g., 1-5): Generally indicates your age and blood pressure are within a favorable range. Continue healthy lifestyle habits.
Moderate Risk Factor (e.g., 6-12): Suggests that either your age, blood pressure, or a combination may warrant closer attention. Discuss with your doctor.
High Risk Factor (e.g., 13+): Indicates a potentially elevated risk. It is crucial to consult a healthcare professional for a comprehensive evaluation and management plan.
Note: These ranges are illustrative. Actual medical risk stratification is complex and involves many more factors (cholesterol, diabetes, smoking, family history, etc.).
Key Takeaways:
Regularly monitor your blood pressure.
Maintain a healthy lifestyle: balanced diet, regular exercise, stress management, and adequate sleep.
Consult your doctor for personalized advice and management of blood pressure.
