Nephritis is a term used for inflammation of the kidneys. It is not one single disease. Different forms of nephritis can affect different parts of the kidney and may develop because of infections, autoimmune conditions, medicines or other underlying disorders.

The appropriate nephritis treatment depends on the type of nephritis, its cause, the degree of kidney involvement and whether complications are present. Some cases are temporary, while others can cause progressive kidney damage if not identified and managed appropriately.

At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides specialist evaluation and management of kidney diseases and inflammatory kidney conditions.

What Is Nephritis?

Nephritis refers broadly to inflammation involving kidney tissue.

Depending on the part of the kidney affected, doctors may diagnose different forms, including:

• Glomerulonephritis
• Interstitial nephritis
• Certain forms of pyelonephritis
• Lupus-related kidney inflammation
• Other immune-mediated kidney diseases

The inflammation can interfere with filtration and may lead to abnormalities such as blood or protein in the urine.

What Causes Nephritis?

The cause varies according to the specific type.

Autoimmune disorders

Conditions in which the immune system mistakenly attacks healthy tissue can affect the kidneys. Lupus is one example.

Infections

Certain infections can trigger kidney inflammation directly or through an immune response.

Medications

Some medicines can cause inflammation of the kidney's interstitial tissue. The risk depends on the medicine, dose, duration and individual susceptibility.

Immune system abnormalities

Some kidney diseases develop when abnormal immune reactions affect the glomeruli, which are the kidney's microscopic filtering units.

Other medical conditions

Certain systemic diseases can affect the kidneys and produce inflammatory changes.

Because the causes are diverse, identifying the specific type of nephritis is an important part of treatment.

Symptoms of Nephritis

Symptoms can range from mild to severe. Some people may have no noticeable symptoms initially.

Possible signs include:

• Blood in the urine
• Foamy or protein-containing urine
• Swelling around the eyes, ankles or feet
• Reduced urine output
• Changes in urine frequency
• High blood pressure
• Fatigue
• Nausea
• Flank or back discomfort
• Fever in some infection-related conditions
• Shortness of breath when significant fluid accumulation occurs

These symptoms can occur with other medical conditions as well, so testing is needed for an accurate diagnosis.

How Is Nephritis Diagnosed?

A nephrologist may use several tests to determine whether kidney inflammation is present and identify its cause.

Urine examination

Urine testing can detect:

• Blood
• Protein
• White blood cells
• Cellular casts
• Other abnormalities

The pattern of urine findings can provide important clues about the type of kidney disease.

Blood tests

Blood testing may include:

• Serum creatinine
• eGFR
• Electrolytes
• Blood counts
• Albumin
• Other disease-specific tests

Immune and autoimmune testing

When an immune-mediated kidney disease is suspected, doctors may recommend tests for specific antibodies and complement levels.

Kidney ultrasound

Ultrasound can provide information about kidney size, structure and possible urinary tract abnormalities.

Kidney biopsy

In selected patients, a kidney biopsy may be recommended. It involves examining a small sample of kidney tissue under a microscope and can help identify the exact type of kidney inflammation.

A biopsy is not necessary for every patient.

Why Finding the Cause Matters

There is no single medicine that treats every type of nephritis.

For example, treatment for infection-related kidney inflammation differs from treatment for an autoimmune glomerular disease. Similarly, medication-related interstitial nephritis may require a different approach.

Therefore, treatment should be based on the underlying diagnosis rather than simply treating symptoms.

Nephritis Treatment Options

Treatment is individualized according to the cause and severity of kidney inflammation.

Treating the underlying infection

If infection is responsible, appropriate antimicrobial treatment may be required.

Reviewing medicines

When medication-related kidney inflammation is suspected, a healthcare professional may identify and discontinue the responsible medicine when appropriate.

Patients should not stop prescription medicines on their own.

Controlling blood pressure

High blood pressure can accompany kidney inflammation and may further stress the kidneys. Appropriate blood pressure management is often an important part of treatment.

Managing protein in the urine

When significant proteinuria is present, doctors may use medicines that help reduce protein loss and protect kidney function, depending on the patient's circumstances.

Immunosuppressive treatment

Certain autoimmune and inflammatory kidney diseases may require corticosteroids or other immunosuppressive medicines.

These medicines are not appropriate for every form of nephritis and should be used under specialist supervision.

Managing fluid and salt balance

Patients with swelling, high blood pressure or reduced kidney function may receive individualized dietary and fluid recommendations.

Treating complications

Depending on severity, treatment may also address:

• Anemia
• Electrolyte abnormalities
• Fluid overload
• Reduced kidney function
• Bone and mineral abnormalities

Is Nephritis Curable?

The outlook depends on the specific type of nephritis.

Some causes may improve significantly after appropriate treatment. Other forms can become chronic and gradually reduce kidney function.

Early diagnosis is particularly important when nephritis is associated with an autoimmune or progressive kidney disease.

Can Nephritis Cause Kidney Failure?

Yes. Severe or persistent kidney inflammation can damage the filtering structures and reduce kidney function.

However, not everyone with nephritis develops kidney failure.

The risk depends on factors such as:

• Type of nephritis
• Severity of inflammation
• Degree of proteinuria
• Kidney function at diagnosis
• Underlying disease
• Response to treatment
• Duration of kidney damage

Regular monitoring can help doctors identify changes in kidney function.

Nephritis and Protein in Urine

Protein in urine can be an important sign of kidney damage.

Healthy kidneys normally retain most proteins in the bloodstream. When the kidney's filtration barrier becomes damaged, proteins such as albumin can leak into urine.

Persistent proteinuria should be investigated because it can occur in several kidney diseases, including some forms of nephritis.

Nephritis and Blood in Urine

Blood in the urine can sometimes originate from inflammation of the kidney's filtering units.

However, blood in urine can also result from:

• Kidney stones
• Urinary tract infections
• Prostate problems
• Structural abnormalities
• Other urinary tract conditions

A proper medical evaluation is necessary to determine the cause.

Lifestyle and Kidney Care During Nephritis

Lifestyle measures may support overall kidney health, but they do not replace treatment for the underlying inflammatory disease.

Depending on your medical condition, your doctor may recommend:

• Appropriate blood pressure control
• Diabetes management
• A balanced diet
• Limiting excessive salt intake
• Appropriate physical activity
• Avoiding unnecessary medicines
• Regular kidney function monitoring
• Following prescribed treatment consistently

Fluid intake should be individualized. People with significant kidney dysfunction may require specific fluid recommendations.

Foods to Avoid During Nephritis

There is no universal "nephritis diet."

Dietary needs depend on kidney function, blood potassium, blood pressure, swelling, proteinuria and the underlying kidney disease.

Some patients may need to reduce sodium intake, while others may require individualized adjustments to protein, potassium or phosphorus.

It is better to obtain dietary advice from a qualified healthcare professional rather than following a restrictive diet found online.

When Should You See a Nephrologist?

Specialist assessment may be appropriate if you have:

• Persistent protein in urine
• Repeated blood in urine
• Unexplained swelling
• Elevated creatinine
• Reduced eGFR
• Uncontrolled blood pressure
• Suspected autoimmune kidney disease
• Recurrent kidney abnormalities
• Rapid changes in kidney function

Early nephrology evaluation can help establish the cause and determine whether additional testing is required.

Warning Signs That Need Prompt Medical Attention

Seek urgent medical attention if kidney symptoms are accompanied by:

• Very low or absent urine
• Severe breathlessness
• Rapidly increasing swelling
• Severe weakness
• Confusion
• Persistent vomiting
• High fever with urinary symptoms
• Sudden deterioration in kidney function

These symptoms may indicate significant kidney dysfunction or another serious medical condition.

Frequently Asked Questions

What is the best treatment for nephritis?

Treatment depends on the type and cause. It may involve treating an infection, stopping a responsible medicine, controlling blood pressure or using immune-modifying treatment for selected autoimmune kidney diseases.

Can nephritis go away?

Some forms can improve significantly with appropriate treatment. Other types may become chronic and require long-term management.

Does nephritis always cause pain?

No. Kidney inflammation may occur without significant pain. Abnormal urine tests or blood tests may be the first indication of a kidney problem.

Is nephritis the same as a kidney infection?

No. Kidney infection is one possible cause of kidney inflammation, but nephritis also includes several non-infectious inflammatory kidney diseases.

Can nephritis cause swelling in the legs?

Yes. Some forms of nephritis can cause protein loss and reduced kidney function, which may contribute to fluid retention and swelling.

Can nephritis lead to dialysis?

Severe kidney inflammation can sometimes cause kidney failure requiring dialysis. In some acute situations dialysis may be temporary, while advanced irreversible kidney disease may require long-term kidney replacement therapy.

Conclusion

Nephritis treatment depends on identifying the specific type and cause of kidney inflammation. Symptoms such as blood or protein in urine, swelling, high blood pressure and declining kidney function should not be ignored, particularly when they persist or worsen.

Early assessment can help determine whether the condition is related to infection, medication, autoimmune disease or another kidney disorder. Appropriate treatment and regular monitoring may help protect kidney function and reduce the risk of complications.
