The Progression of Diabetic Kidney Disease: From Early Hyperfiltration to End-Stage Renal Failure

Diabetic kidney disease:

Diabetic kidney disease is a serious complication of diabetes that can develop over time. It occurs when high blood sugar levels damage the kidneys, impairing their ability to filter waste and excess fluid from the blood.

Stages of diabetic kidney disease:

Here's an overview of the stages of diabetic kidney disease:

Stage 1 - Hyperfiltration and Hypertrophy:

  • In this early stage, the kidneys actually work harder and filter more than normal.
  • This is the body's initial response to high blood sugar levels.
  • There are usually no noticeable symptoms at this stage.

Stage 2 - Mild Kidney Damage:

  • During this stage, there is some structural damage to the kidneys, but the filtering function is still normal.
  • Small amounts of protein may start to leak into the urine.
  • There are usually no symptoms at this stage.

Stage 3 - Moderate Kidney Damage:

  • The filtering function of the kidneys starts to decline.
  • Waste products can begin to build up in the blood.
  • Protein levels in the urine increase.
  • High blood pressure may develop.
  • Some symptoms like fatigue and swelling may appear.

Stage 4 - Severe Kidney Damage:

  • Kidney function declines significantly, to 15-30% of normal.
  • Waste products accumulate rapidly in the blood.
  • High blood pressure and fluid retention become more pronounced.
  • Symptoms like nausea, loss of appetite, and confusion may appear.

Stage 5 - End-Stage Renal Disease (ESRD):

  • Kidney function drops below 15% of normal.
  • Dialysis or a kidney transplant is required to sustain life.
  • Severe symptoms like vomiting, drowsiness, and profound fatigue are common.


It's important to note that the progression through these stages is not always linear, and some people may not experience all the stages. Early detection and proper management of diabetes and high blood pressure can help slow the progression of diabetic kidney disease.
