What it is

Chronic kidney disease is a sustained reduction in kidney function (eGFR < 60 for ≥ 3 months) and/or kidney damage (such as albumin in the urine). It is usually silent early and is staged by eGFR and albuminuria together.

Why it matters

CKD is common, often undetected, and a powerful multiplier of cardiovascular risk — most people with CKD die of cardiovascular disease before reaching kidney failure. Early detection and treatment can markedly slow progression and reduce events.

What works for Chronic Kidney Disease

BioSignal’s clinical summary, most important first.

  1. Blood pressure control (ACE inhibitors / ARBs when albuminuria is present)
  2. Glucose control in diabetes
  3. SGLT2 inhibitors (slow progression, even in non-diabetic CKD)
  4. Lipid and cardiovascular risk management
  5. Avoiding nephrotoxins (e.g., NSAID overuse)

Who is at risk

  • Diabetes (the leading cause)
  • High blood pressure
  • Older age
  • Cardiovascular disease
  • Family history
  • Obesity and metabolic syndrome

How it's diagnosed

Diagnosed and staged with two measures together: eGFR (from creatinine, sometimes cystatin C) and urine albumin-to-creatinine ratio (UACR). Both are needed — significant CKD can exist with a normal eGFR if albuminuria is present.

  • eGFR (serum creatinine ± cystatin C)
  • Urine albumin-to-creatinine ratio (UACR)
  • Blood pressure
  • Metabolic labs (HbA1c, lipids)

Frequently asked questions

Can chronic kidney disease be slowed?

Yes. Controlling blood pressure and glucose, using ACE inhibitors/ARBs when there's albuminuria, and adding SGLT2 inhibitors can meaningfully slow progression — the earlier, the better.

Why measure urine albumin if my eGFR is normal?

Because albuminuria can reveal kidney damage before eGFR drops, and it independently raises cardiovascular and kidney risk. eGFR and UACR are read together.

Evidence summary

Slowing CKD with blood-pressure control, RAAS blockade for albuminuria, and SGLT2 inhibitors is established by large randomized trials (including in non-diabetic CKD); CKD's amplification of cardiovascular risk is well documented.
