The liver and kidneys perform different but interconnected functions, so problems affecting either organ can sometimes produce similar symptoms.

Kidneys help filter waste and excess fluid from the blood, while the liver performs important functions involving metabolism, bile production, nutrient processing and removal of certain substances from the body.

Some kidney and liver diseases can remain silent during their early stages. Symptoms may become noticeable only when organ function has been significantly affected. NIDDK notes that early chronic kidney disease often has no symptoms, while cirrhosis may also produce few or no symptoms until the liver is substantially damaged.

Possible warning signs include:

• Persistent tiredness or weakness

• Swelling of the legs, ankles or feet

• Changes in urine

• Itchy skin

• Nausea or poor appetite

• Abdominal discomfort

• Unexplained weight changes

• Yellowing of the skin or eyes

• Changes in mental alertness in advanced disease

• Breathlessness when fluid accumulates

Having one of these symptoms does not automatically mean that both the liver and kidneys are affected. Proper testing is needed to identify the cause.

At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides specialist evaluation of kidney disease and kidney-related complications associated with systemic and liver conditions.

Why Can Liver and Kidney Problems Have Similar Symptoms?

The liver and kidneys have separate roles, but severe disease affecting one organ can influence the body's overall fluid balance, metabolism and circulation.

For example, kidney dysfunction can cause accumulation of excess fluid, leading to swelling. Advanced liver disease can also cause swelling of the legs and fluid accumulation in the abdomen.

Similarly, fatigue, nausea and poor appetite can occur in both kidney and liver disorders.

This overlap means that symptoms alone cannot reliably identify which organ is responsible.

Early Symptoms May Be Easy to Miss

One of the challenges with kidney and liver disease is that significant disease may exist before obvious symptoms appear.

Kidney Disease

Early CKD frequently produces no noticeable symptoms. Blood and urine testing may be needed to identify reduced kidney function or kidney damage.

Liver Disease

Some liver conditions are also silent. For example, metabolic-associated fatty liver disease may cause few or no symptoms, while cirrhosis may remain unnoticed until substantial liver damage has occurred.

This is why people with risk factors such as diabetes, high blood pressure, obesity, viral hepatitis or a relevant family history may require appropriate medical screening.

Kidney-Related Symptoms to Watch For

Kidney disease can produce symptoms as kidney function declines.

Changes in Urination

Possible changes include:

• Urinating more or less often

• Foamy urine

• Blood in urine

• Changes in urine appearance

• Reduced urine output in significant kidney dysfunction

Foamy urine can occur when protein is leaking into the urine, while blood in urine may occur with certain kidney diseases.

Swelling

Kidney disease can cause edema, particularly around:

• Ankles

• Feet

• Legs

• Hands

• Face

This can happen when the kidneys have difficulty removing excess salt and fluid or when significant protein is lost in urine.

Persistent Fatigue

Advanced kidney disease may be associated with tiredness, sleep problems, difficulty concentrating and weakness. Anemia is also a common complication of CKD and can contribute to fatigue and breathlessness.

Itching and Dry Skin

People with advanced kidney disease may develop generalized itching, dry skin or changes in skin appearance.

Muscle Cramps

Muscle cramps can occur with advanced kidney disease and may also have several other causes.

Nausea and Poor Appetite

As kidney dysfunction becomes more advanced, some people develop nausea, vomiting, poor appetite or weight loss.

Liver-Related Symptoms to Recognize

Liver disease can produce a different pattern of symptoms.

Yellow Eyes or Skin

Jaundice, or yellowing of the skin and whites of the eyes, can occur when bilirubin accumulates.

It can be a sign of liver or bile-duct disease and requires medical assessment.

Dark Urine

Dark urine can occur with certain liver conditions, including some forms of hepatitis. It can also have causes unrelated to the liver.

Itchy Skin

Persistent itching is a recognized symptom of several liver conditions and can occur in advanced liver disease.

Abdominal Discomfort

Liver-related discomfort may occur in the upper-right part of the abdomen. Some liver diseases, however, cause no abdominal pain.

Abdominal Swelling

Advanced liver disease can cause ascites, meaning accumulation of fluid within the abdomen.

Easy Bruising or Bleeding

Advanced cirrhosis can affect the body's ability to maintain normal blood clotting and may be associated with easier bruising or bleeding.

Confusion or Changes in Thinking

Severe liver disease can be associated with confusion, difficulty thinking, memory changes and altered sleep patterns.

Symptoms That Can Occur With Both Kidney and Liver Disease

Some symptoms overlap substantially.

Symptom	Possible kidney connection	Possible liver connection
Fatigue	CKD, anemia, advanced kidney dysfunction	Chronic liver disease or cirrhosis
Swelling in legs	Fluid retention or protein loss	Fluid retention associated with advanced liver disease
Itching	Advanced CKD-associated pruritus	Several liver and bile-duct disorders
Poor appetite	Advanced kidney dysfunction	Chronic liver disease
Nausea	Advanced kidney dysfunction	Some liver diseases
Weight change	CKD-related nutritional problems	Liver disease or malnutrition
Abdominal swelling	Fluid accumulation in severe cases	Ascites in advanced liver disease
Urine changes	Protein, blood or altered urine output	Dark urine can occur with some liver disorders
Breathlessness	Fluid overload or anemia	May occur indirectly with significant fluid accumulation

These symptoms are not diagnostic on their own. Clinical examination and appropriate laboratory testing are needed.

When Kidney Disease May Be Related to Liver Disease

Certain advanced liver disorders can affect kidney function.

For example, severe liver disease can be associated with significant changes in circulation and fluid regulation that may contribute to kidney dysfunction.

A patient with liver disease and a rising creatinine level therefore needs careful evaluation because reduced kidney function can have several possible causes, including dehydration, infection, medicines, acute kidney injury and other conditions.

A high creatinine level in a person with liver disease should not automatically be assumed to represent permanent kidney failure.

Common Conditions That Can Affect the Liver and Kidneys

Several underlying health conditions can place stress on both organs.

Diabetes

Diabetes can contribute to kidney disease and is also strongly associated with metabolic liver disease. Kidney monitoring may include eGFR and urine albumin testing in people with diabetes.

High Blood Pressure

Long-standing hypertension is an important risk factor for kidney disease.

Alcohol-Associated Liver Disease

Excessive alcohol use can cause liver injury and may contribute indirectly to kidney problems through dehydration, illness and other systemic effects.

Viral Hepatitis

Chronic hepatitis B and C can cause long-term liver damage and cirrhosis. Certain infections and immune-related conditions may also affect kidney function.

Medication-Related Problems

Some medicines can affect kidney function, while others can cause liver injury. Medication safety depends on the specific drug, dose and patient's medical condition.

Prescription medicines, over-the-counter drugs and herbal supplements should therefore be reviewed with a healthcare professional when kidney or liver abnormalities are present.

How Are Liver and Kidney Problems Diagnosed?

Symptoms provide clues, but laboratory and imaging tests are often needed.

Tests for Kidney Function

A doctor may order:

• Serum creatinine

• eGFR

• Urea

• Electrolytes

• Urinalysis

• Urine albumin-to-creatinine ratio

• Blood pressure measurement

Kidney disease may be present even when symptoms are minimal, making testing particularly important in higher-risk individuals.

Tests for Liver Function

Depending on the suspected condition, testing may include:

• ALT

• AST

• Alkaline phosphatase

• Bilirubin

• Albumin

• Other blood tests

NIDDK notes that liver blood tests, imaging and sometimes liver biopsy can be used when cirrhosis is suspected.

Imaging

Depending on symptoms, doctors may recommend:

• Ultrasound

• CT

• MRI

• Other specialized imaging

Imaging can help assess organ structure, fluid accumulation, obstruction or other abnormalities.

Additional Testing

Depending on the findings, additional testing may include:

• Viral hepatitis testing

• Autoimmune testing

• Metabolic investigations

• Kidney-specific tests

• Liver-specific tests

• Biopsy in selected cases

The exact investigation plan depends on the suspected diagnosis.

Can Kidney and Liver Problems Be Treated?

Treatment depends entirely on the underlying condition.

There is no single medicine that treats all liver and kidney problems.

Kidney treatment may involve:

• Blood-pressure management

• Diabetes management

• Treatment of proteinuria

• Management of electrolyte abnormalities

• Treatment of specific kidney diseases

• Fluid management

• Dialysis when clinically indicated

• Kidney transplantation for selected patients with kidney failure

For CKD, controlling blood pressure and managing other risk factors can help protect remaining kidney function.

Liver treatment depends on the diagnosis and may involve treatment of viral hepatitis, metabolic liver disease, alcohol-associated liver disease, autoimmune disease or complications of cirrhosis.

Can Kidney and Liver Function Improve?

Sometimes.

The possibility of improvement depends on the cause.

Certain episodes of acute kidney injury can improve when the underlying problem is treated promptly.

Similarly, some liver conditions can improve when the cause is identified and treated before irreversible scarring develops.

However, established advanced CKD or cirrhosis may not be completely reversible.

This is why identifying the cause early is important.

What Lifestyle Measures Can Support Both Organs?

Lifestyle changes should complement—not replace—medical treatment.

Avoid Excess Alcohol

People with liver disease should discuss alcohol use with their healthcare professional because continued alcohol exposure can worsen some liver conditions.

Control Blood Sugar

Good diabetes management can reduce the risk of kidney complications and is also important for metabolic health.

Manage Blood Pressure

Blood-pressure control is an important component of kidney protection.

Follow an Individualized Diet

People with kidney or liver disease may have different nutritional requirements. Advanced disease may require individualized adjustments to sodium, protein, potassium, phosphorus or fluid intake.

Avoid extreme diets or “liver and kidney detox” programs.

Review Medicines and Supplements

Do not assume that herbal or natural products are harmless. Tell your doctor about all prescription medicines, over-the-counter drugs and supplements.

When Should You Seek Medical Attention?

Arrange medical evaluation when you have persistent or unexplained:

• Swelling

• Foamy urine

• Blood in urine

• Reduced urine output

• Yellow eyes or skin

• Persistent itching

• Unexplained fatigue

• Recurrent nausea or vomiting

• Unexplained weight loss

• Abdominal swelling

• Persistent upper-right abdominal discomfort

• Abnormal kidney or liver blood tests

Early kidney disease can be silent, so testing may be necessary even when symptoms are mild.

When Are Liver and Kidney Symptoms an Emergency?

Seek urgent medical attention for symptoms such as:

• Severe difficulty breathing

• Chest pain

• Confusion or markedly altered consciousness

• Very little or no urine

• Rapidly increasing swelling

• Vomiting that prevents adequate fluid intake

• Vomiting blood

• Black or bloody stools

• Severe abdominal pain

• Sudden yellowing with significant illness

• Rapid deterioration in overall condition

These symptoms can indicate serious kidney, liver, cardiovascular or gastrointestinal complications and should not be managed at home without medical assessment.

Kidney and Liver Evaluation at Prabhakar Bhurke Clinic

At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides individualized assessment for patients with kidney disease and complex medical conditions that may affect multiple organs.

Depending on the patient's condition, evaluation may include:

• Kidney-function assessment

• Creatinine and eGFR review

• Urine protein and albumin testing

• Electrolyte assessment

• Blood-pressure evaluation

• Review of liver-related laboratory findings

• Medication and supplement review

• Evaluation of kidney complications associated with systemic disease

• Dialysis assessment when clinically indicated

• Coordination with appropriate liver, gastroenterology or other specialists when required

The objective is to determine the cause of abnormal kidney or liver-related findings rather than treating symptoms alone.

Frequently Asked Questions

What are the common symptoms of liver and kidney problems?

Common overlapping symptoms can include fatigue, swelling, itching, nausea, appetite changes and changes in weight. Kidney disease may additionally cause foamy urine, blood in urine or changes in urine output, while advanced liver disease can cause jaundice, abdominal fluid accumulation and easy bruising.

Can kidney problems cause yellow eyes?

Kidney disease itself is not a typical direct cause of jaundice. Yellowing of the eyes is more commonly associated with increased bilirubin and liver or bile-duct disorders and requires medical evaluation.

Can liver disease cause kidney problems?

Yes. Advanced liver disease can be associated with kidney dysfunction, and a person with liver disease and abnormal kidney tests may require evaluation for several possible causes.

Is swelling a sign of both liver and kidney disease?

It can occur with both. Kidney disease can cause edema from fluid retention or significant protein loss, while advanced liver disease can cause leg swelling and abdominal fluid accumulation.

Does itching indicate liver or kidney disease?

Itching can occur in both kidney and liver disorders, but it also has many other causes. Persistent generalized itching should be evaluated rather than attributed automatically to either organ.

What tests check kidney and liver function?

Kidney assessment commonly includes creatinine, eGFR, electrolytes and urine testing. Liver assessment may include ALT, AST, alkaline phosphatase, bilirubin and albumin, with imaging or additional testing when appropriate.

Can a person have kidney disease without symptoms?

Yes. Early CKD frequently has no noticeable symptoms, and testing may be the only way to detect it.

Which doctor should I see for kidney and liver problems?

A nephrologist specializes in kidney diseases and kidney-function problems. Liver disorders are generally evaluated by a gastroenterologist or hepatologist. When both organs are involved, coordinated specialist care may be appropriate.

Conclusion

The symptoms of liver and kidney problems can overlap, which can make it difficult to determine the affected organ from symptoms alone.

Kidney disease may cause swelling, urine changes, proteinuria, fatigue, itching, muscle cramps and, in advanced disease, nausea or breathlessness. Liver disease can cause fatigue, itching, abdominal discomfort, jaundice, swelling, ascites, easy bruising and changes in mental function when disease becomes advanced.

Importantly, both kidney and liver diseases can remain silent during their early stages. Appropriate blood tests, urine testing and imaging can help identify abnormalities before complications become severe.

If you have persistent swelling, abnormal urine, jaundice, unexplained fatigue, itching, abdominal swelling or abnormal kidney or liver test results, seek professional medical evaluation.
