Blood Pressure & Kidney Damage Risk Tool

Enter your blood pressure readings, duration of hypertension, and clinical risk factors. This tool calculates your BP classification, estimates cumulative kidney damage risk, and generates a kidney-protective action plan.

Step 1 — Your Blood Pressure Readings

For best accuracy, enter your most recent average — ideally the mean of 2–3 readings taken at rest on separate occasions.

Enter your typical blood pressure

Systolic (top number)

Diastolic (bottom number)

Step 2 — Hypertension History

How long have you had elevated blood pressure?

Are you currently on blood pressure medication?

BP control status (if on medication)

Not on medication

On medication — BP well controlled

On medication — still above target

On medication — persistently elevated

Step 3 — Kidney Damage Risk Factors

Do you have diabetes?

Type 1 diabetes

Type 2 — well controlled

Type 2 — poorly controlled

Prediabetes

Diabetes + hypertension together cause kidney damage far faster than either alone.

Have you had a urine protein test (dipstick or ACR)?

Never tested

Negative for protein

Trace or 1+

2+ or above / elevated ACR

Protein in the urine is the earliest detectable sign of kidney damage.

Do you know your kidney function result (eGFR / creatinine)?

Never tested

Normal (eGFR > 90)

Mildly reduced (eGFR 60–89)

Moderately reduced (eGFR 30–59)

Severely reduced (eGFR < 30)

Step 4 — Additional Risk Factors

Your Age

Family history of kidney disease?

Do you regularly take NSAIDs (ibuprofen, diclofenac, naproxen)?

No / rarely

Occasionally (1–2 times/month)

Regularly (weekly or more)

Do you smoke?

Never

Ex-smoker

Current smoker

🩺 Doctor’s Recommended Home Monitors

Accurate readings are critical for tracking hypertension and kidney health. Wrist monitors are notoriously inaccurate. If you need to monitor your blood pressure at home, I recommend these clinically validated, upper-arm monitors to my patients:

Omron Platinum Upper Arm Monitor Highly accurate, clinically validated, and stores historical trends. View on Amazon

Welch Allyn Home BP Monitor Medical-grade technology adapted for easy, accurate home use. View on Amazon

Evidence-Based Lifestyle Interventions

Sodium restriction

−5 to −8 mmHg systolic

Reduce sodium below 2,300 mg/day. The single most impactful dietary change.

Aerobic exercise

−5 to −7 mmHg systolic

150 mins/week of moderate exercise. Effects comparable to a low-dose medication.

Weight loss

−1 mmHg per kg lost

A 10 kg weight loss produces a clinically significant 10 mmHg reduction.

Smoking cessation

Major organ protection

Smoking causes acute BP spikes and progressive endothelial damage.
