Chronic Kidney Disease Stages: Symptoms, Causes and Treatment

Chronic Kidney Disease (CKD) is a long-term condition in which the kidneys gradually lose their ability to filter waste and excess fluids from the blood. Because kidney damage often progresses slowly, many people may not notice symptoms in the early stages. Understanding the stages of chronic kidney disease can help patients seek timely medical care and prevent complications.

At Tambaram Medical Center, our specialists provide comprehensive diagnosis and treatment for kidney diseases, helping patients across Tambaram and Chennai manage kidney health effectively.

What Is Chronic Kidney Disease?

Chronic kidney disease occurs when the kidneys become damaged and cannot filter blood properly. This results in a buildup of toxins and fluids in the body, which can lead to various health problems.

Stages of Chronic Kidney Disease

CKD is divided into five stages based on the estimated glomerular filtration rate (eGFR), which measures kidney function.

Stage 1 – Normal Kidney Function with Mild Damage

In this stage, kidney function is still normal but there may be early signs of kidney damage such as protein in urine.

Stage 2 – Mild Reduction in Kidney Function

Kidney function begins to decline slightly. Many patients still do not notice symptoms.

Stage 3 – Moderate Kidney Damage

Symptoms may start appearing, including fatigue, swelling, and changes in urination.

Stage 4 – Severe Kidney Damage

Kidney function is significantly reduced. Medical treatment and lifestyle changes become essential.

Stage 5 – Kidney Failure

This stage is also called end-stage renal disease (ESRD). Dialysis or kidney transplant may be required.
