Introduction
Chronic Kidney Disease (CKD) is a long-term condition in which the kidneys gradually lose their ability to filter waste products, excess fluids, and toxins from the blood. CKD develops slowly over months or years and may progress to kidney failure if not diagnosed and treated early.
There are several types of chronic kidney disease, each caused by different underlying conditions. Understanding the type of CKD is essential because treatment varies depending on the cause, severity, and stage of kidney damage.
At Prabhakar Bhurke Clinic, our super specialist nephrologist specializes in the early diagnosis, evaluation, and management of all types of chronic kidney disease, helping patients preserve kidney function and improve their quality of life.
What Is Chronic Kidney Disease?
Chronic Kidney Disease is defined as kidney damage or reduced kidney function that persists for more than three months.
The kidneys perform several vital functions, including:
-
Filtering waste products from the blood
-
Removing excess water
-
Maintaining electrolyte balance
-
Regulating blood pressure
-
Producing hormones that support red blood cell production and bone health
When these functions decline, waste products build up in the body, affecting overall health.
Common Types of Chronic Kidney Disease
1. Diabetic Kidney Disease (Diabetic Nephropathy)
Diabetes is one of the leading causes of CKD worldwide.
High blood sugar damages the tiny blood vessels in the kidneys over time, reducing their ability to filter waste effectively.
Common Features
-
Protein in the urine
-
High blood pressure
-
Gradually increasing creatinine levels
-
Declining eGFR
Good blood sugar control and regular monitoring are essential to slow disease progression.
2. Hypertensive Kidney Disease
Long-standing high blood pressure can damage kidney blood vessels and reduce blood flow to the kidneys.
Risk Factors
-
Poorly controlled hypertension
-
Heart disease
-
Obesity
-
Smoking
Managing blood pressure is one of the most effective ways to protect kidney function.
3. Glomerular Disease (Glomerulonephritis)
This group of diseases affects the glomeruli, the tiny filtering units of the kidneys.
Causes may include:
-
Autoimmune disorders
-
Infections
-
Certain medications
-
Genetic conditions
Symptoms
-
Blood in the urine
-
Protein in the urine
-
Swelling
-
High blood pressure
Early treatment may reduce kidney damage.
4. Polycystic Kidney Disease (PKD)
Polycystic Kidney Disease is an inherited disorder characterized by multiple fluid-filled cysts developing in the kidneys.
Over time, the cysts enlarge and reduce normal kidney function.
Symptoms
-
Flank pain
-
High blood pressure
-
Blood in the urine
-
Kidney stones
-
Progressive kidney enlargement
Regular follow-up is essential to monitor kidney health.
5. Chronic Interstitial Nephritis
This condition involves long-term inflammation of the kidney tissue between the filtering units.
Possible causes include:
-
Certain medications
-
Recurrent infections
-
Autoimmune diseases
-
Toxin exposure
Treatment focuses on identifying and addressing the underlying cause.
6. Obstructive Kidney Disease
Long-term blockage of urine flow can gradually damage the kidneys.
Common causes include:
-
Kidney stones
-
Enlarged prostate
-
Urinary tract abnormalities
-
Tumors
Prompt treatment of urinary obstruction helps prevent permanent kidney damage.
7. Lupus Nephritis
Lupus nephritis is a complication of Systemic Lupus Erythematosus (SLE) in which the immune system attacks the kidneys.
Treatment typically includes medications to reduce inflammation and protect kidney function.
8. Reflux Nephropathy
This condition develops when urine flows backward from the bladder toward the kidneys, often due to vesicoureteral reflux.
Repeated infections and urine reflux can cause kidney scarring over time.
Stages of Chronic Kidney Disease
CKD is classified into five stages based on the Estimated Glomerular Filtration Rate (eGFR).
Stage 1
-
Normal or near-normal kidney function
-
Evidence of kidney damage present
Stage 2
-
Mild reduction in kidney function
-
Often no obvious symptoms
Stage 3
-
Moderate reduction in kidney function
-
Fatigue
-
Swelling
-
High blood pressure
-
Changes in urination
Stage 4
-
Severe reduction in kidney function
-
Increased risk of complications
-
Preparation for dialysis or transplant may begin
