Chronic Kidney Disease in Children: Causes, Early Signs, Growth Problems and Treatment

Learn about chronic kidney disease in children, including causes, early symptoms, growth concerns, diagnosis, treatment, dialysis and long-term kidney care.

23 Sep, 2026

Chronic kidney disease in children is a long-term condition in which the kidneys have persistent structural damage or reduced ability to perform their normal functions.

The kidneys help remove waste products, maintain fluid and electrolyte balance, support blood-pressure regulation and contribute to normal bone and red blood cell health.

When kidney function is reduced over a prolonged period, a child's growth, nutrition, bone development and overall health can be affected.

Unlike many adult cases of chronic kidney disease, childhood CKD is often related to congenital, inherited or developmental conditions of the kidneys and urinary tract.

Early diagnosis and regular specialist monitoring are important because children with kidney disease have changing medical needs as they grow.

At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides specialist kidney evaluation and care. Children with suspected or confirmed kidney disease may require assessment and coordinated care with an appropriately qualified pediatric nephrology team depending on their age and clinical condition.

How Common Is Chronic Kidney Disease in Children?

Chronic kidney disease is less common in children than in adults, but it can have significant effects on a child's health and development.

CKD may be identified:

  • Before birth through prenatal imaging

  • During infancy

  • During childhood

  • During adolescence

Some children are diagnosed because of recurrent urinary infections, abnormal growth, high blood pressure or abnormal blood and urine tests.

Others may already have a known congenital kidney or urinary tract condition.

What Causes Chronic Kidney Disease in Children?

The causes of CKD in children differ from those commonly seen in adults.

Congenital Abnormalities of the Kidneys and Urinary Tract

Structural abnormalities present from birth are important causes of kidney problems in children.

These may involve:

  • Abnormal kidney development

  • Small or poorly developed kidneys

  • Urinary tract obstruction

  • Abnormal urine drainage

  • Vesicoureteral reflux

  • Other congenital urinary tract abnormalities

Some children are diagnosed before birth through ultrasound.

Inherited Kidney Diseases

Certain kidney diseases can run in families.

Examples may include:

  • Polycystic kidney disease

  • Alport syndrome

  • Cystinuria

  • Other genetic kidney disorders

A family history of kidney failure, cystic kidney disease or unexplained kidney problems can be clinically important.

Glomerular Diseases

The glomeruli are tiny filtering units within the kidneys.

Certain diseases affecting these filters can lead to:

  • Protein in the urine

  • Blood in the urine

  • Swelling

  • High blood pressure

  • Declining kidney function

The treatment depends on the specific glomerular condition.

Recurrent Kidney Injury

Repeated or severe episodes of kidney injury may contribute to long-term kidney damage in some children.

Possible factors include:

  • Severe infections

  • Prolonged urinary obstruction

  • Certain medications

  • Serious illness

  • Recurrent acute kidney injury

Other Medical Conditions

Certain systemic or metabolic conditions can also affect kidney function.

The cause must be carefully investigated because treatment depends on the underlying diagnosis.

What Are the Early Signs of Chronic Kidney Disease in Children?

Early CKD may cause very few obvious symptoms.

Some children may appear well despite abnormal kidney-function tests.

Possible signs can include:

  • Poor growth

  • Poor weight gain

  • Reduced appetite

  • Persistent tiredness

  • Nausea

  • Vomiting

  • Swelling around the eyes or feet

  • Changes in urination

  • Excessive urination

  • Reduced urine output

  • Recurrent urinary infections

  • High blood pressure

  • Blood or protein in the urine

These symptoms can also occur in conditions unrelated to CKD.

A medical evaluation is required to determine the cause.

How Can Kidney Disease Affect a Child's Growth?

One feature that makes chronic kidney disease in children different from adult CKD is its potential effect on growth and development.

Kidney disease can influence:

  • Appetite

  • Nutrition

  • Hormonal balance

  • Bone health

  • Acid-base balance

  • Mineral balance

Children with significant CKD may have slower growth or difficulty gaining weight.

For this reason, pediatric kidney care often involves monitoring:

  • Height

  • Weight

  • Growth pattern

  • Nutritional intake

  • Bone and mineral health

Nutrition should be individualized because unnecessary dietary restrictions can interfere with normal growth.

Can Chronic Kidney Disease Affect School and Daily Activities?

Many children with CKD can attend school and participate in age-appropriate activities.

However, the impact depends on the severity of kidney disease and its treatment.

Some children may experience:

  • Fatigue

  • Frequent medical appointments

  • Dietary restrictions

  • Medication schedules

  • Hospital admissions

  • Dialysis treatment

Parents, caregivers and healthcare professionals may need to work together to support the child's education and daily routine.

Emotional and social support can also be important for children living with a chronic medical condition.

How Is Chronic Kidney Disease Diagnosed in Children?

Diagnosis involves more than a single blood test.

The doctor may assess the child's symptoms, growth, medical history and laboratory findings.

Blood Tests

Tests may include:

  • Serum creatinine

  • Estimated kidney function using age-appropriate calculations

  • Electrolytes

  • Bicarbonate

  • Hemoglobin

  • Calcium

  • Phosphorus

Kidney function in children should be interpreted using methods appropriate for the child's age and body size.

Urine Tests

Urine evaluation may look for:

  • Protein

  • Albumin

  • Blood

  • Infection

  • Other abnormalities

Blood Pressure Measurement

High blood pressure can both result from and contribute to kidney damage.

Blood pressure should be assessed using appropriate pediatric standards.

Ultrasound and Other Imaging

Imaging can help identify:

  • Kidney size

  • Structural abnormalities

  • Urinary obstruction

  • Cysts

  • Abnormal urine drainage

Additional Testing

Depending on the suspected condition, the child may need:

  • Genetic evaluation

  • Specialized blood tests

  • Kidney biopsy

  • Other investigations

Not every child requires all of these tests.

How Is CKD in Children Classified?

Chronic kidney disease is generally assessed according to the degree of kidney function and evidence of kidney damage.

However, interpretation in children requires pediatric-specific assessment.

Doctors may consider:

  • Kidney filtration estimates

  • Urine protein or albumin

  • Structural abnormalities

  • Blood pressure

  • Growth and development

  • Changes over time

A child's kidney-function result should not be interpreted using adult assumptions alone.

Treatment of Chronic Kidney Disease in Children

There is no single treatment that works for every child with CKD.

Management depends on:

  • The cause of kidney disease

  • The degree of kidney-function impairment

  • Age and growth

  • Blood pressure

  • Urine findings

  • Nutritional needs

  • Presence of complications

Treatment may involve several areas of care.

Treating the Underlying Cause

When possible, treatment focuses on the condition responsible for kidney damage.

For example, management may involve addressing:

  • Urinary obstruction

  • Recurrent infection

  • Glomerular disease

  • Genetic conditions

  • Metabolic disorders

Blood Pressure Management

Maintaining appropriate blood pressure can be important for protecting kidney function.

The medicine and treatment targets should be selected specifically for the child.

Managing Protein in the Urine

Protein or albumin in the urine can be an important marker of kidney damage.

Treatment may include medicines or other strategies depending on the child's diagnosis.

Nutrition and Growth Support

Children need sufficient nutrition for normal growth and development.

Dietary planning should be individualized.

Depending on kidney function and laboratory results, adjustments may be needed for:

  • Sodium

  • Protein

  • Potassium

  • Phosphorus

  • Calories

  • Fluid intake

A pediatric renal dietitian may be involved when appropriate.

Managing Anemia

Kidney disease can contribute to anemia in some children.

Doctors may investigate the cause and recommend appropriate treatment.

Bone and Mineral Management

The kidneys help maintain calcium and phosphorus balance.

Advanced CKD can affect bone and mineral metabolism, which is particularly important during childhood growth.

Regular monitoring and appropriate treatment may be required.

Can Chronic Kidney Disease in Children Be Reversed?

The answer depends on the cause.

Some kidney-function changes caused by a reversible condition may improve after treatment.

However, established chronic kidney damage may not be completely reversible.

The goals of treatment may therefore include:

  • Identifying the cause

  • Protecting remaining kidney function

  • Slowing progression

  • Supporting normal growth

  • Managing complications

  • Maintaining quality of life

Early intervention can be particularly valuable because children are still growing and developing.

What Happens If Kidney Function Becomes Very Low?

When kidney function becomes severely reduced, the child may develop complications that cannot be adequately controlled with medical management alone.

Kidney replacement treatment may then be considered.

Options can include:

Peritoneal Dialysis

Peritoneal dialysis uses the lining of the abdomen as a filtering membrane.

This method may be particularly suitable for some children, depending on their medical condition and family circumstances.

Hemodialysis

Hemodialysis uses a machine and specialized filter to remove waste products and excess fluid from the blood.

The treatment schedule is individualized.

Kidney Transplantation

For appropriately selected children with kidney failure, kidney transplantation may provide long-term kidney replacement.

Transplant evaluation involves detailed medical assessment.

The choice and timing of kidney replacement therapy depend on the child's health, kidney function and overall clinical circumstances.

How Can Parents Help Protect a Child's Kidney Health?

Parents and caregivers can support treatment by:

  • Giving prescribed medicines correctly

  • Attending follow-up appointments

  • Monitoring blood pressure if advised

  • Following individualized dietary guidance

  • Encouraging appropriate fluid intake

  • Reporting changes in urine output

  • Seeking care for recurrent urinary infections

  • Avoiding unprescribed medicines and supplements

  • Informing doctors about all medicines being taken

Children should not be given herbal products or supplements marketed as kidney cures without professional advice.

Medicines That Require Extra Caution

Some medicines may require dose adjustments when kidney function is reduced.

Parents should always inform healthcare professionals that their child has kidney disease.

Avoid giving over-the-counter medicines repeatedly without checking whether they are appropriate for the child's age and kidney function.

Certain pain medicines can affect kidney function in susceptible children.

When Should Parents Seek Urgent Medical Attention?

Seek urgent medical evaluation if a child with known or suspected kidney disease develops:

  • Very little or no urine

  • Significant swelling

  • Severe breathlessness

  • Persistent vomiting

  • Severe dehydration

  • High fever with flank or abdominal pain

  • Confusion or unusual drowsiness

  • Severe weakness

  • Rapid deterioration in general health

A child with urinary obstruction and infection may require urgent treatment.

Long-Term Follow-Up Is Important

Children with CKD often require ongoing follow-up as they grow.

A treatment plan may need to change because:

  • Kidney function may change

  • Body size changes

  • Nutritional needs change

  • Medicines may need adjustment

  • Blood pressure targets may change

  • Growth and puberty require monitoring

Regular follow-up helps detect complications early.

Transition From Pediatric to Adult Kidney Care

Children with chronic kidney disease who reach adolescence may eventually transition to adult nephrology services.

A planned transition can help young people understand:

  • Their kidney condition

  • Their medicines

  • Dietary needs

  • Follow-up requirements

  • The importance of blood-pressure and kidney-function monitoring

Preparing gradually for adult care can support continuity of treatment.

Chronic Kidney Disease Care and Specialist Evaluation

Children with suspected CKD require appropriate assessment because childhood kidney disease has unique causes and treatment requirements.

At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides specialist kidney assessment and management. Depending on the child's age and diagnosis, care may involve coordination or referral to a qualified pediatric nephrologist and multidisciplinary pediatric care team.

Evaluation may include:

  • Review of kidney-function results

  • Assessment of urine abnormalities

  • Blood-pressure evaluation

  • Review of ultrasound and imaging reports

  • Assessment of congenital or structural kidney conditions

  • Evaluation of protein in urine

  • Assessment of chronic kidney disease progression

  • Planning for advanced kidney care when appropriate

  • Coordination with pediatric specialists when required

Frequently Asked Questions

What causes chronic kidney disease in children?

Common causes include congenital abnormalities of the kidneys and urinary tract, inherited kidney diseases, glomerular diseases, urinary obstruction and certain other medical conditions.

What are the first signs of kidney disease in children?

Some children have no early symptoms. Possible signs include poor growth, poor appetite, swelling, recurrent urinary infections, abnormal urine findings, fatigue and high blood pressure.

Can a child live a normal life with chronic kidney disease?

Many children with CKD can attend school and participate in daily activities. The impact depends on the severity of kidney disease, complications and treatment requirements.

Can chronic kidney disease in children be cured?

Some reversible causes of kidney dysfunction can improve with treatment. Established chronic kidney damage may not be completely reversible, but treatment can help manage complications and protect remaining kidney function.

Does chronic kidney disease affect growth?

Yes. Significant CKD can affect appetite, nutrition, hormonal balance and bone health, potentially influencing growth and development.

Can children with kidney disease need dialysis?

Yes. Children with severe kidney failure may require peritoneal dialysis or hemodialysis when kidney function is insufficient and complications cannot be adequately controlled.

Can a child with kidney failure receive a kidney transplant?

Appropriately selected children may be evaluated for kidney transplantation. Suitability depends on the child's diagnosis, overall health and transplant assessment.

Which doctor treats chronic kidney disease in children?

Children with CKD should generally be evaluated and managed by a qualified pediatric nephrologist, often with support from a multidisciplinary pediatric healthcare team.

Conclusion

Chronic kidney disease in children is different from adult kidney disease in many important ways. Congenital abnormalities, inherited disorders and childhood glomerular diseases are among the conditions that can affect kidney function.

Early CKD may not always cause obvious symptoms, making regular medical monitoring important for children with known kidney or urinary tract abnormalities.

Because kidney disease can affect growth, nutrition, blood pressure, bone health and development, treatment requires careful and age-appropriate planning.

With regular monitoring, appropriate treatment of the underlying condition and specialist pediatric kidney care, many complications can be identified and managed early.

For kidney-related evaluation and specialist guidance, Dr. Sandip Prabhakar Bhurke at Prabhakar Bhurke Clinic can provide assessment and help coordinate appropriate kidney care, including referral or multidisciplinary management with a qualified pediatric nephrology team when required.
