In diabetic kidney disease, microalbuminuria typically progresses to:

• A. Macroalbuminuria with declining eGFR
• B. No albuminuria
• C. Improved eGFR
• D. Less albuminuria

Answer: (A)

The main idea here is that diabetic kidney disease commonly moves from early kidney damage marked by microalbuminuria to more advanced damage with overt protein loss and falling kidney function. Microalbuminuria means a small amount of albumin leaks into the urine, signaling glomerular injury. If the disease continues to progress, the damage worsens and leads to macroalbuminuria (a larger amount of albumin in the urine) along with a decline in the estimated glomerular filtration rate (eGFR) as more nephrons are lost. So the combination of new or increasing albuminuria beyond the micro range and a decreasing eGFR is the typical trajectory.

The other options don’t fit this natural course: no albuminuria would imply no detectable kidney damage, which contradicts the onset of microalbuminuria; improved eGFR is not the usual progression after microalbuminuria; less albuminuria would suggest improvement rather than progression. In practice, good control of blood sugar and blood pressure can slow or modestly reverse albuminuria, but the typical progression in untreated or progressive disease is to macroalbuminuria with declining eGFR.
