The kidneys perform several essential functions, including removing waste products from the blood, maintaining fluid and electrolyte balance, regulating blood pressure and supporting red blood cell production.

Different diseases can interfere with these functions.

Some kidney problems develop suddenly, while others progress gradually over months or years. Certain conditions cause noticeable symptoms, whereas early kidney disease may cause few or no symptoms.

Some of the commonly encountered kidney problems include:

• Chronic kidney disease

• Acute kidney injury

• Kidney stones

• Kidney infections

• Protein or albumin in the urine

• Blood in the urine

• Diabetic kidney disease

• Kidney disease associated with high blood pressure

• Glomerular diseases

• Polycystic kidney disease

• Urinary obstruction

• Electrolyte and acid-base disorders

• Advanced kidney failure

Understanding the difference between these conditions is important because their treatment can be very different.

At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides individualized evaluation and management for a wide range of kidney conditions.

1. Chronic Kidney Disease

Chronic kidney disease (CKD) occurs when kidney damage or reduced kidney function persists over time.

Common causes include:

• Diabetes

• High blood pressure

• Glomerular diseases

• Inherited kidney disorders

• Recurrent kidney injury

• Certain systemic diseases

CKD may progress slowly, and many people do not notice symptoms in its early stages.

As kidney function becomes more impaired, possible symptoms can include:

• Swelling

• Fatigue

• Changes in urination

• Poor appetite

• Nausea

• Itching

• Muscle cramps

• Breathlessness in some situations

Treatment focuses on identifying the cause, protecting remaining kidney function and managing complications.

2. Acute Kidney Injury

Acute kidney injury (AKI) is a sudden deterioration in kidney function.

Possible triggers include:

• Severe dehydration

• Serious infection

• Low blood pressure

• Certain medicines

• Urinary obstruction

• Major surgery or severe illness

• Other conditions affecting kidney blood flow or kidney tissue

Creatinine may increase over a relatively short period.

Unlike established chronic kidney damage, some cases of AKI can improve substantially when the underlying cause is recognized and treated promptly.

Severe AKI may sometimes require temporary dialysis.

3. Kidney Stones

Kidney stones are hard deposits that form from substances present in urine.

Some stones remain in the kidney without causing symptoms. Others move into the ureter and can cause significant pain or urinary obstruction.

Possible symptoms include:

• Severe flank pain

• Pain extending toward the abdomen or groin

• Blood in the urine

• Nausea

• Vomiting

• Burning while urinating

• Frequent urination

Treatment depends on the stone's size, location, composition and whether there is obstruction or infection.

Depending on the situation, management may include observation, medicines, shock wave lithotripsy, ureteroscopy with laser treatment or PCNL.

4. Kidney Infection

A kidney infection, medically known as pyelonephritis, is usually associated with a bacterial urinary infection that involves the kidney.

Symptoms may include:

• Fever

• Chills

• Flank or back pain

• Burning during urination

• Frequent urination

• Nausea or vomiting

• Feeling generally unwell

Kidney infection should be evaluated promptly, particularly when symptoms are severe.

An obstructing stone together with infection can be particularly dangerous because urine drainage may be blocked. Such situations may require urgent treatment.

5. Protein in the Urine

Healthy kidneys normally prevent large amounts of protein from passing into urine.

When kidney filters are damaged, protein or albumin may leak into the urine.

This may occur with:

• Diabetes

• High blood pressure

• Glomerular diseases

• Certain inflammatory conditions

• Other kidney disorders

Proteinuria may not cause obvious symptoms.

A urine albumin-to-creatinine ratio or other urine protein test can help identify abnormal protein loss.

Persistent proteinuria deserves medical evaluation because it can be an important marker of kidney damage.

6. Blood in the Urine

Blood in the urine is called hematuria.

It may be visible to the naked eye or detected only through laboratory testing.

Possible causes include:

• Kidney stones

• Urinary infections

• Glomerular kidney diseases

• Urinary tract conditions

• Certain structural abnormalities

• Other medical conditions

Blood in urine should not automatically be attributed to kidney stones.

Persistent or unexplained hematuria may require further investigation.

7. Diabetic Kidney Disease

Diabetes can gradually damage the small blood vessels and filtering structures of the kidneys.

Early diabetic kidney disease may not cause noticeable symptoms.

Regular monitoring can include:

• eGFR

• Urine albumin

• Blood pressure

• Blood glucose

• Other tests based on the individual's health

Treatment may include appropriate glucose and blood-pressure management and kidney-protective medicines when indicated.

Early detection can be particularly important because kidney damage may develop before symptoms appear.

8. High Blood Pressure Related Kidney Damage

High blood pressure and kidney disease have a close relationship.

Long-standing hypertension can damage kidney blood vessels and filtration structures.

At the same time, kidney disease can contribute to difficult-to-control blood pressure.

People with kidney disease may therefore require careful blood-pressure monitoring and treatment.

Medication selection depends on factors such as:

• Kidney function

• Potassium levels

• Albuminuria

• Other medical conditions

• Current medicines

Do not change blood-pressure medicines without medical guidance.

9. Glomerular Kidney Diseases

The glomeruli are microscopic filtering units inside the kidneys.

Diseases affecting these structures can cause:

• Protein in urine

• Blood in urine

• Swelling

• High blood pressure

• Reduced kidney function

Some glomerular diseases are associated with autoimmune or inflammatory conditions.

Diagnosis may require blood tests, urine studies, imaging and, in selected cases, a kidney biopsy.

Treatment depends on the specific disease rather than simply the creatinine level.

10. Polycystic Kidney Disease

Polycystic kidney disease (PKD) is an inherited condition in which multiple cysts develop in the kidneys.

Depending on the type and severity, PKD can be associated with:

• Enlarged kidneys

• High blood pressure

• Kidney stones

• Blood in urine

• Recurrent infections

• Progressive loss of kidney function

Management involves monitoring kidney function and blood pressure and addressing complications.

Selected patients with rapidly progressive disease may be considered for specific disease-modifying treatment under specialist supervision.

11. Urinary Obstruction

Urine needs to flow freely from the kidneys through the ureters into the bladder.

A blockage can interfere with this process.

Possible causes include:

• Kidney or ureteral stones

• Enlarged prostate

• Narrowing of the urinary tract

• Masses

• Blood clots

• Structural abnormalities

Prolonged obstruction can damage kidney function.

When obstruction is suspected, imaging such as ultrasound or CT may be recommended.

Treatment focuses on restoring urine drainage and addressing the underlying cause.

12. Kidney Failure

Kidney failure occurs when the kidneys can no longer adequately perform their essential functions.

It can develop after severe acute kidney injury or as a consequence of advanced chronic kidney disease.

Possible complications include:

• Fluid overload

• High potassium

• Metabolic acidosis

• Uremic symptoms

• Severe anemia

• Mineral and bone abnormalities

Some patients with kidney failure may require kidney replacement therapy, such as:

• Hemodialysis

• Peritoneal dialysis

• Kidney transplantation

Dialysis is not started simply because creatinine crosses one universal number. The overall clinical condition and complications are considered.

Why Kidney Problems Can Be Difficult to Notice

One reason kidney disease is often detected late is that the kidneys can lose considerable function before symptoms become obvious.

A person may feel completely well despite having:

• Reduced eGFR

• Protein in urine

• Early diabetic kidney disease

• High blood pressure affecting the kidneys

This is why people at increased risk may benefit from periodic kidney-function testing.

Who Is at Higher Risk of Kidney Problems?

Kidney screening may be particularly relevant for people with:

• Diabetes

• High blood pressure

• Cardiovascular disease

• Family history of kidney disease

• Previous acute kidney injury

• Recurrent kidney stones

• Recurrent urinary infections

• Certain autoimmune diseases

• Obesity or other metabolic risk factors

• Known structural kidney abnormalities

The appropriate tests and frequency of monitoring depend on individual risk.

Common Symptoms That May Suggest a Kidney Problem

Kidney problems can produce different symptoms depending on the condition.

Possible warning signs include:

• Swelling of the feet, ankles or face

• Foamy urine

• Blood in urine

• Significant changes in urine output

• Persistent flank pain

• Recurrent urinary infections

• High blood pressure

• Persistent fatigue

• Nausea

• Itching

• Muscle cramps

• Breathlessness

These symptoms are not specific to kidney disease.

For example, swelling can have heart, liver, venous or medication-related causes, while back or flank pain may have muscular or urinary causes.

Testing is often needed to identify the actual problem.

How Are Kidney Problems Diagnosed?

A nephrologist may combine several types of information rather than relying on one test.

Kidney Function Blood Tests

Common tests include:

• Serum creatinine

• eGFR

• Urea

• Electrolytes

• Bicarbonate

• Hemoglobin

• Calcium and phosphorus when appropriate

Urine Testing

Depending on the suspected condition, testing may include:

• Urinalysis

• Urine albumin

• Urine protein

• Urine culture

• Other specialized urine tests

Blood Pressure Measurement

Blood-pressure assessment is important because hypertension can both cause and worsen kidney disease.

Imaging

Ultrasound, CT or other imaging may be used when doctors need to evaluate:

• Kidney size

• Kidney stones

• Cysts

• Obstruction

• Structural abnormalities

Specialized Tests

Some kidney diseases require additional blood tests, genetic testing or a kidney biopsy.

The choice depends on the clinical situation.

How Are Common Kidney Problems Treated?

There is no single treatment that works for every kidney condition.

Management may involve:

Treating the underlying cause: Infection, obstruction, autoimmune disease, diabetes and other conditions require different approaches.

Protecting kidney function: Blood-pressure control, diabetes management and appropriate kidney-protective medicines can help reduce further damage in selected patients.

Managing complications: Electrolyte abnormalities, anemia, fluid retention and mineral-bone disorders may require specific treatment.

Kidney replacement therapy: Advanced kidney failure may require dialysis or transplantation when clinically indicated.

The treatment plan should be individualized according to diagnosis, kidney function, laboratory results and overall health.

Lifestyle Steps That Support Kidney Health

Lifestyle measures can complement medical treatment.

Manage Blood Pressure

Follow the blood-pressure target recommended by your healthcare professional and take prescribed medicines consistently.

Control Diabetes

For people with diabetes, appropriate glucose management is an important part of kidney protection.

Avoid Excessive Salt

Reducing excessive sodium intake can support blood-pressure and fluid management.

Maintain Appropriate Hydration

Fluid requirements are not identical for everyone.

People with advanced kidney disease or certain heart conditions may need fluid restrictions, while others may need to pay particular attention to adequate fluid intake.

Be Careful With Painkillers

Some NSAIDs can affect kidney function, particularly in susceptible individuals.

Ask a healthcare professional before using them regularly if you have kidney disease.

Avoid Unverified Kidney Detox Products

Herbal products and supplements marketed as kidney cleansers are not automatically safe.

Some may interact with medicines or potentially affect kidney function.

When Should You See a Nephrologist?

Consider specialist kidney evaluation if you have:

• Persistently high creatinine

• Reduced eGFR

• Persistent protein or albumin in urine

• Unexplained blood in urine

• Difficult-to-control hypertension

• Recurrent kidney stones

• Repeated kidney infections

• Progressive kidney-function decline

• Significant electrolyte abnormalities

• Advanced CKD

• Suspected kidney failure

Early evaluation can help clarify the cause and determine appropriate management.

When Is a Kidney Problem an Emergency?

Certain symptoms require immediate medical attention.

Seek urgent medical care for:

• Very little or no urine

• Severe breathlessness

• Severe or rapidly increasing swelling

• Confusion or altered consciousness

• Persistent vomiting with significant dehydration

• Severe flank pain accompanied by fever or chills

• Fainting

• Rapid deterioration

• Severe weakness

A fever with suspected urinary obstruction is particularly concerning because an infected blocked urinary tract can become a serious emergency.

Frequently Asked Questions

What are the most common kidney problems?

Common kidney conditions include chronic kidney disease, acute kidney injury, kidney stones, kidney infections, proteinuria, diabetic kidney disease, hypertension-related kidney disease, glomerular disorders, inherited kidney diseases, urinary obstruction and kidney failure.

What is the first sign of a kidney problem?

There is no single first sign. Some kidney problems cause swelling, urine changes, high blood pressure or fatigue, while early chronic kidney disease may cause no noticeable symptoms.

Can kidney problems be cured?

Some acute kidney problems can improve or resolve when the underlying cause is treated. Established chronic kidney damage may not be completely reversible, but appropriate treatment can help preserve remaining kidney function and manage complications.

How do I know if my kidneys are not working properly?

Blood tests such as creatinine and eGFR, along with urine testing for albumin or protein, can provide important information about kidney function. Additional testing may be necessary depending on the suspected condition.

Can kidney stones damage the kidneys?

A stone does not necessarily damage the kidney, but prolonged obstruction, repeated infection or other complications can impair kidney function.

Is high creatinine always kidney failure?

No. Creatinine can rise because of acute kidney injury, dehydration, urinary obstruction, certain medicines and other factors. Kidney function should be assessed using the overall clinical picture, including eGFR and other tests.

Which doctor treats kidney problems?

A nephrologist specializes in medical kidney conditions and kidney-function disorders. Some urinary tract problems, particularly those requiring surgical procedures, may also require evaluation by a urologist.

Conclusion

The term “common kidney problems” covers a wide range of conditions, from kidney stones and infections to chronic kidney disease, acute kidney injury and advanced kidney failure.

These conditions do not all produce the same symptoms or require the same treatment. Some can improve when the underlying cause is treated, while chronic kidney diseases often require long-term monitoring and management.

Because early kidney disease can be silent, people with diabetes, high blood pressure, recurrent stones, previous kidney injury or other risk factors should discuss appropriate kidney testing with a healthcare professional.

If you have abnormal kidney-function results, persistent urine abnormalities, recurrent stones, swelling or other concerns about your kidneys, specialist evaluation can help identify the cause and guide treatment.
