Quick Answer

Yes. Advanced chronic kidney disease can contribute to peripheral neuropathy.

This is often called:

Uremic neuropathy

It is more commonly associated with significant or advanced loss of kidney function than with mild kidney impairment.

Symptoms may include:

• Numbness
• Tingling
• Burning
• Pain
• Reduced sensation
• Restless sensations
• Muscle weakness
• Muscle cramps
• Balance problems
• Walking difficulties

Symptoms frequently begin in the feet and lower legs.

But there is an important point:

Having kidney disease does not automatically mean kidney disease is the only cause of your neuropathy.

Diabetes, vitamin deficiencies, medications, spinal problems, and other conditions may also contribute.

What Do the Kidneys Actually Do?

Most people know the kidneys make urine.

But they do much more.

Healthy kidneys help:

• Filter waste products from the blood
• Regulate fluid balance
• Maintain electrolyte balance
• Help regulate blood pressure
• Maintain acid-base balance
• Participate in red blood cell regulation
• Support bone and mineral metabolism

When kidney function declines significantly, changes occur throughout the body.

The nervous system can be affected too.

What Is Chronic Kidney Disease?

Chronic kidney disease, commonly abbreviated CKD, means kidney structure or function has been abnormal for a prolonged period.

CKD can range from relatively mild impairment to advanced kidney failure.

Not everyone with CKD develops neuropathy.

Neurological complications become more concerning as kidney dysfunction becomes more advanced.

What Is Uremia?

When kidney function becomes severely impaired, substances normally removed or regulated by the kidneys can accumulate or become imbalanced.

The resulting systemic illness is referred to as:

Uremia

Uremia can affect many parts of the body, including the nervous system.

Peripheral nerve dysfunction associated with advanced kidney failure is often called:

Uremic neuropathy

What Does Uremic Neuropathy Feel Like?

Symptoms vary, but patients may describe:

• Numb toes
• Tingling feet
• Burning sensations
• Pins and needles
• Aching
• Reduced sensation
• Restlessness
• Muscle cramps
• Weakness

Symptoms often begin in the lower extremities.

As with many generalized neuropathies, the longest nerves tend to become affected first.

Why Do Symptoms Usually Begin in the Feet?

Many metabolic neuropathies are:

Length-dependent

The nerves traveling to your toes are among the longest peripheral nerves in your body.

Long nerves can be particularly vulnerable to metabolic disturbances.

So symptoms may begin in:

Toes → Feet → Lower legs

and progress upward if the neuropathy becomes more advanced.

In more severe cases, the hands may eventually become involved.

Why Would Kidney Failure Damage Nerves?

The exact mechanism is complex.

Advanced kidney disease can create an internal environment that is unfavorable for normal nerve function.

Possible contributors include:

• Accumulation of substances normally cleared by the kidneys
• Metabolic abnormalities
• Electrolyte disturbances
• Oxidative stress
• Inflammation
• Other changes associated with severe kidney dysfunction

Rather than one single “toxin,” kidney-related neuropathy likely reflects multiple metabolic disturbances affecting peripheral nerves.

Does Mild Kidney Disease Usually Cause Neuropathy?

Not necessarily.

Uremic neuropathy has traditionally been associated primarily with more advanced kidney failure.

That distinction matters.

Suppose someone has mildly reduced kidney function and numb feet.

We should not automatically conclude:

“Your kidneys caused your neuropathy.”

We should still consider:

• Diabetes
• Prediabetes
• Vitamin B12 deficiency
• Medication effects
• Alcohol exposure
• Thyroid disease
• Nerve compression
• Spinal conditions
• Autoimmune disease
• Other neurological causes

The degree of kidney dysfunction matters.

Why Diabetes Makes This Complicated

Diabetes is one of the most common causes of both:

• Chronic kidney disease

and

• Peripheral neuropathy

So imagine a patient who has:

Diabetes + Kidney disease + Numb feet

What caused the neuropathy?

Diabetes?

Kidney disease?

Both?

Possibly another condition as well?

That is why we shouldn’t force every neuropathy into one diagnostic box.

More Than One Cause Can Be Present

A patient with kidney disease might also have:

• Diabetes
• B12 deficiency
• Medication-related neuropathy
• Lumbar spinal stenosis
• Alcohol-related nerve damage
• Thyroid disease

The body doesn’t follow the rule:

“Only one diagnosis allowed.”

Sometimes several problems affect the same nervous system.

Our job is to identify as many meaningful contributors as possible.

Can Kidney Disease Cause Restless Legs?

Restless legs syndrome is relatively common among people with advanced kidney disease, particularly those receiving dialysis.

Restless legs syndrome is different from peripheral neuropathy.

Classic restless legs symptoms include:

• An urge to move the legs
• Symptoms that worsen during rest
• Symptoms that improve temporarily with movement
• Symptoms that are usually worse in the evening or at night

A patient with kidney disease may have:

• Neuropathy
• Restless legs syndrome
• Muscle cramps

at the same time.

Those symptoms need to be separated rather than lumped together.

What About Nighttime Muscle Cramps?

People with kidney disease may also experience muscle cramps.

Cramps are not automatically neuropathy.

A muscle cramp typically involves:

• Sudden tightening
• Pain
• Visible or palpable muscle contraction
• Temporary difficulty relaxing the muscle

Electrolyte balance, fluid shifts, medications, circulation, muscle fatigue, and other factors may contribute.

Again:

The description matters.

How Is Kidney Function Measured?

Kidney evaluation commonly includes blood and urine testing.

Important measurements may include:

• Serum creatinine
• Estimated glomerular filtration rate, or eGFR
• Urine albumin testing
• Electrolytes
• Other laboratory studies depending on the situation

No single number tells the entire story.

What Is eGFR?

eGFR stands for:

Estimated Glomerular Filtration Rate

It is an estimate of how effectively the kidneys are filtering blood.

In general, lower eGFR values indicate reduced kidney filtration.

But eGFR must be interpreted in context.

A single abnormal result does not necessarily establish chronic kidney disease.

Clinicians also consider:

• Whether the abnormality persists
• Urine findings
• Medical history
• Age
• Other evidence of kidney damage

Why Urine Testing Matters

Kidney evaluation isn’t based only on blood tests.

Albumin or protein in the urine may provide important information about kidney damage.

A person can have evidence of kidney disease even before filtration declines dramatically.

This is especially important in people with:

• Diabetes
• High blood pressure
• Other kidney risk factors

Can Kidney Disease Cause Weakness?

Yes, but weakness in someone with kidney disease can have several possible explanations.

These may include:

• Neuropathy
• Anemia
• Muscle loss
• Electrolyte disturbances
• Deconditioning
• Medication effects
• Other illnesses

So when a patient says:

“My legs feel weak,”

we need to determine what “weak” actually means.

Is it:

True loss of muscle strength?

Fatigue?

Poor balance?

Pain limiting movement?

Those are different problems.

Why Anemia Matters

Healthy kidneys participate in the body’s regulation of red blood cell production.

Advanced kidney disease can contribute to anemia.

Anemia may cause:

• Fatigue
• Weakness
• Reduced exercise tolerance
• Shortness of breath

A patient may interpret those symptoms as worsening neuropathy.

This is another example of why the entire medical picture matters.

Kidney Disease Changes How We Think About Medications

The kidneys help eliminate many medications and their metabolites.

When kidney function declines, certain medications may:

• Accumulate
• Require dose adjustment
• Produce more side effects

This becomes especially important in older adults taking several medications.

The question isn’t merely:

“Is this drug normally safe?”

It may also be:

“Is this dose appropriate for this person’s kidney function?”

Don’t Adjust Medication on Your Own

If you have chronic kidney disease, don’t change prescription medications because you are worried about kidney clearance.

Instead, discuss the issue with:

• Your prescribing clinician
• Your nephrologist
• Your pharmacist

Some medications require dose adjustments as kidney function declines.

Others may not.

The decision should be individualized.

Supplements Deserve Extra Attention Too

Patients sometimes assume:

“It’s natural, so my kidneys don’t matter.”

That’s not necessarily true.

Supplements contain biologically active compounds.

Some supplements:

• May accumulate
• May interact with medications
• May contain minerals or electrolytes
• May be inappropriate in advanced kidney disease

If you have significant kidney disease, discuss supplements with an appropriate healthcare professional.

More Is Not Always Better

This principle appears repeatedly throughout the Learning Center because it is so important.

If someone has neuropathy, they may begin taking:

• B vitamins
• Magnesium
• Herbal products
• Electrolyte products
• “Nerve support” formulas

But kidney disease can change how the body handles certain substances.

The best supplement plan for one patient may be inappropriate for another.

Treat the patient—not the supplement label.

Can Dialysis Improve Uremic Neuropathy?

Adequate dialysis may help reduce some of the metabolic disturbances associated with advanced kidney failure.

In some patients, neurological symptoms may stabilize or improve.

But established nerve damage may not disappear completely.

Recovery varies according to:

• Severity
• Duration
• Overall health
• Other neuropathy causes
• Adequacy of treatment

Dialysis decisions and management belong with the patient’s kidney-care team.

What About Kidney Transplantation?

Successful kidney transplantation can substantially improve the metabolic abnormalities associated with kidney failure.

Neuropathy may improve in some patients after successful transplantation, particularly when ongoing uremia is corrected.

But again, recovery is variable.

If nerve damage has been severe or longstanding, some symptoms may persist.

Does Improving Kidney Function Repair Nerves Immediately?

No.

This is similar to what we discussed with B12 deficiency and medication-related neuropathy.

Correcting the underlying problem and recovering from nerve injury are not the same thing.

A patient’s kidney-related metabolic environment may improve faster than damaged peripheral nerves recover.

Neurological improvement, when it occurs, may take time.

Can Kidney Disease Affect My Balance?

Potentially.

Peripheral neuropathy may reduce sensory information coming from the feet.

Muscle weakness, anemia, blood-pressure changes, medication effects, and deconditioning may also contribute.

That means balance problems in someone with kidney disease may be multifactorial.

This is especially important because falls can have serious consequences.

Watch for Dizziness When Standing

Some patients with kidney disease also experience blood-pressure problems.

If you become dizzy or lightheaded when standing, tell your healthcare team.

That may be related to:

• Blood-pressure medication
• Fluid balance
• Autonomic dysfunction
• Dialysis-related factors
• Other medical conditions

Don’t automatically call every balance problem “neuropathy.”

How We Evaluate Possible Kidney-Related Neuropathy at Advanced Integrated Medical

When someone with kidney disease develops neuropathy symptoms, I want to understand:

• How advanced is the kidney disease?
• What is the recent eGFR?
• Is diabetes present?
• How well is glucose controlled?
• When did neuropathy symptoms begin?
• Are symptoms symmetrical?
• Are they primarily sensory or motor?
• Is weakness developing?
• Are there restless-leg symptoms?
• Are there muscle cramps?
• Has B12 been evaluated?
• What medications are being taken?
• What supplements are being taken?
• Could another neurological or spinal problem be contributing?

Depending on the situation, coordination with the patient’s primary-care clinician, nephrologist, neurologist, pharmacist, or other healthcare professionals may be appropriate.

The goal is not to assume:

“Kidney disease equals neuropathy.”

The goal is to determine whether kidney dysfunction is actually part of the explanation.

Treatment Depends on the Cause

If advanced kidney disease is contributing to neuropathy, treatment may involve several pieces:

• Appropriate kidney-disease management
• Diabetes management when applicable
• Medication review
• Nutritional assessment
• Treatment of documented deficiencies
• Management of neuropathic pain
• Strength and balance rehabilitation
• Fall prevention
• Foot protection
• Management of restless legs when present
• Appropriate specialist coordination

No single neuropathy treatment replaces good management of the underlying kidney disease.

Protect Your Feet

If neuropathy reduces sensation in the feet, foot protection becomes especially important.

Check your feet regularly for:

• Blisters
• Cuts
• Redness
• Pressure areas
• Cracks
• Swelling
• Drainage
• Open wounds

Avoid walking barefoot when protective sensation is reduced.

Properly fitting footwear matters.

And if diabetes is also present, foot protection becomes even more important.

About Dr. Dee

Dr. D. Scott (“Dee”) Stevens has spent nearly four decades helping patients with peripheral neuropathy, chronic pain, musculoskeletal disorders, sports injuries, and regenerative medicine.

Throughout his career, he has cared for patients from all walks of life—including professional, collegiate, and Olympic athletes, professional football players, Major League Baseball players, professional boxers, and MMA fighters.

One lesson I’ve learned is that the farther we get into a patient’s medical history, the less likely it is that one diagnosis explains everything.

A patient may have kidney disease.

And diabetes.

And spinal degeneration.

And several medications.

And neuropathy.

The challenge isn’t simply naming every diagnosis.

It’s understanding which ones are affecting the patient today.

Dr. Dee’s Clinical Pearl

If a patient with kidney disease tells me:

“My feet are numb because of my kidneys,”

my next question is:

“How do we know?”

Kidney disease may absolutely be contributing.

But I still want to know:

• How advanced is it?
• Is diabetes present?
• Has B12 been checked?
• Could medications be contributing?
• Is there nerve compression?
• Does the neurological pattern fit?

A possible explanation is not always the complete explanation.

Dr. Dee’s Office Conversation

Patient: “Doctor, my kidney function isn’t good, so I guess that’s why my feet are numb.”

Dr. Dee: “It may be part of the reason. How advanced is your kidney disease?”

Patient: “I’m not sure.”

Dr. Dee: “And do you have diabetes?”

Patient: “Yes, for about 20 years.”

Dr. Dee: “Then we may have more than one possible contributor. Rather than choosing one too quickly, let’s look at the whole picture.”

Patient: “So both could be affecting my nerves?”

Dr. Dee: “Exactly.”

Facing One of the Biggest Fears

“My Kidneys Are Getting Worse. Does That Mean My Neuropathy Will Keep Getting Worse Too?”

Not necessarily.

Neuropathy progression depends on many factors.

The important questions are:

• What is causing the neuropathy?
• How well is the kidney disease being managed?
• Is diabetes also present?
• Are medications appropriately dosed?
• Are nutritional problems present?
• Is function changing?
• What can we protect?

Don’t assume that one declining laboratory number automatically predicts your neurological future.

Talk with your healthcare team.

Understand the problem.

Then focus on the factors that can be addressed.

Patient Success Principle #25

Protect the Systems That Protect Your Nerves

Nerve health does not exist in isolation.

Your nerves depend on the health of the rest of your body.

That includes:

• Blood sugar
• Kidney function
• Nutrition
• Circulation
• Physical activity
• Medication safety

Sometimes protecting your nerves means treating the nerves directly.

Sometimes it means protecting the organs and systems that support them.

Taking care of your whole body is part of taking care of your nerves.

Ask Dr. Dee

“Doctor, if I have kidney disease and neuropathy, does that mean I have uremic neuropathy?”

Not necessarily.

Uremic neuropathy is more strongly associated with advanced kidney failure.

If kidney dysfunction is mild or moderate, other causes may deserve equal or greater consideration.

The question should be:

Does the severity of my kidney disease, my neurological pattern, and my overall medical history support kidney disease as a major contributor?

That requires looking at the whole patient.

Lesson I’ve Learned in Nearly 40 Years

The Body Doesn’t Operate in Separate Departments

We often divide medicine into specialties.

Kidneys.

Nerves.

Heart.

Spine.

Nutrition.

Endocrine system.

But your body doesn’t know which specialist treats which organ.

Everything interacts.

Kidney disease can affect medication levels.

Diabetes can affect kidneys and nerves.

Nutrition can affect muscles and nerves.

Neuropathy can affect balance.

Balance affects mobility.

Mobility affects strength.

After nearly four decades of caring for patients, I’ve learned that good healthcare requires us to keep putting the pieces back together.

The Hope Principle

Chronic kidney disease can be frightening.

Peripheral neuropathy can be frightening.

Having both may make the future feel uncertain.

But uncertainty is not the same as hopelessness.

There may still be important things you can do:

• Manage kidney disease carefully
• Control diabetes when present
• Review medications
• Correct appropriate nutritional problems
• Protect your feet
• Improve strength
• Work on balance
• Reduce fall risk
• Stay appropriately active
• Communicate with your healthcare team

Hope doesn’t mean pretending serious disease isn’t serious.

Hope means recognizing that protecting what you still have is meaningful—and improvement, when possible, is worth pursuing.

“I believe the best healthcare decisions are made when patients understand their condition. My job isn’t simply to treat symptoms—it’s to help you understand why they’re happening and what your options are.”

— Dr. D. Scott (“Dee”) Stevens

Frequently Asked Questions

Can kidney disease cause peripheral neuropathy?

Yes. Advanced chronic kidney disease can contribute to peripheral neuropathy, often referred to as uremic neuropathy.

Does mild kidney disease usually cause neuropathy?

Uremic neuropathy is more commonly associated with significant or advanced kidney dysfunction. Other causes should be considered when kidney impairment is mild.

What does kidney-related neuropathy feel like?

Symptoms may include numbness, tingling, burning, pain, reduced sensation, weakness, and balance difficulties, often beginning in the feet.

Why does kidney failure affect nerves?

Advanced kidney dysfunction creates metabolic and biochemical disturbances that can interfere with normal peripheral nerve function.

Can diabetes and kidney disease both contribute to neuropathy?

Yes. Diabetes is a major cause of both kidney disease and peripheral neuropathy, so both may contribute in the same patient.

Can kidney disease cause restless legs?

Restless legs syndrome is common among people with advanced kidney disease, particularly those receiving dialysis. RLS and peripheral neuropathy are different conditions but can coexist.

Can dialysis improve neuropathy?

Adequate dialysis may help stabilize or improve some neurological symptoms in certain patients, although established nerve damage may persist.

Can a kidney transplant improve neuropathy?

Neuropathy may improve in some patients after successful transplantation and correction of uremia, but recovery varies.

Why do medications matter more when kidney function is reduced?

The kidneys help eliminate many medications and metabolites. Reduced kidney function can change drug clearance and may require dose adjustments.

Should people with kidney disease take neuropathy supplements?

Not automatically. Some supplements may be inappropriate in advanced kidney disease. Supplements should be reviewed with an appropriate healthcare professional.
