View Doctor Profile →Diabetic neuropathy is a type of nerve damage caused by diabetes. It can affect the feet, legs, hands, arms, and—in some forms—the nerves controlling organs such as the heart, digestive system, bladder, and sexual organs. The most common form is peripheral neuropathy, which often begins in the feet.
Symptoms can range from tingling, burning, numbness, and pain to weakness and loss of protective sensation. Some people have nerve damage without noticeable symptoms, which is why regular neuropathy and foot screening is important for people with diabetes. The American Diabetes Association’s 2026 Standards recommend assessment for diabetic peripheral neuropathy at diagnosis of type 2 diabetes, five years after type 1 diabetes diagnosis, and at least annually thereafter.
This guide explains the types of diabetic neuropathy, early warning signs, diagnosis, treatment options, foot care, and what you can do to reduce the risk of nerve damage getting worse.

Quick Answer: What Is Diabetic Neuropathy?
Diabetic neuropathy is nerve damage associated with diabetes, usually developing over time in people who have diabetes.
Persistently elevated blood glucose and other metabolic factors can damage nerves and the small blood vessels that supply them. Risk can also be influenced by factors such as longer diabetes duration, high blood pressure, abnormal cholesterol, excess weight, kidney disease, smoking, and alcohol use.
The most common type is diabetic peripheral neuropathy, which usually affects the feet and legs and may later involve the hands and arms.
Everyday Habits That Increase Diabetes Risk
What Does Diabetic Neuropathy Feel Like?
The symptoms depend on which nerves are affected.
Common symptoms of peripheral neuropathy include:
- Burning pain
- Tingling or “pins and needles”
- Numbness
- Shooting or electric-like pain
- Increased sensitivity to touch
- Reduced ability to feel pain
- Reduced ability to sense temperature
- Muscle weakness
- Balance problems
- Changes in the way you walk
Symptoms may be more noticeable at night. Some people experience severe pain, while others mainly notice numbness or loss of sensation.
An important warning
Numbness can be more dangerous than pain.
If you cannot properly feel your feet, you may not notice a blister, cut, burn, pressure injury, or object inside your shoe. A small injury can then develop into a more serious wound or infection.
What Causes Diabetic Neuropathy?
Diabetic neuropathy is linked to diabetes-related damage to nerves and the blood vessels that supply them.
Over time, high blood glucose and elevated blood fats such as triglycerides can contribute to nerve injury. The small blood vessels supplying nerves can also become damaged, reducing the oxygen and nutrients available to nerve tissue.
However, blood glucose is not the only consideration.
Risk can also be higher with:
- Longer duration of diabetes
- Older age
- High blood pressure
- High cholesterol
- Kidney disease
- Overweight or obesity
- Smoking
- Excessive alcohol consumption
- Certain genetic factors
How to Prevent Type 2 Diabetes
Types of Diabetic Neuropathy
There are several types of diabetic neuropathy. A person can have more than one type.
1. Peripheral Neuropathy
This is the most common type.
It usually affects the:
- Feet
- Legs
- Hands
- Arms
It often starts in the feet and can cause burning, tingling, numbness, pain, weakness, and loss of protective sensation.
Peripheral neuropathy can also affect balance and coordination.
2. Autonomic Neuropathy
Autonomic neuropathy affects nerves that control internal organs and automatic body functions.
It can affect the:
- Heart and blood pressure
- Stomach and intestines
- Bladder
- Sexual organs
- Sweat glands
- Ability to recognize low blood glucose
Symptoms depend on the organ system involved. They may include dizziness when standing, digestive problems, bladder problems, abnormal sweating, and sexual dysfunction.
3. Focal Neuropathy
Focal neuropathy affects an individual nerve or a small group of nerves.
It can occur in areas such as the:
- Hand
- Head
- Torso
- Leg
Carpal tunnel syndrome is one example of a nerve compression problem that is more common in people with diabetes.
Symptoms depend on the nerve involved and can develop relatively suddenly.
4. Proximal Neuropathy
Proximal neuropathy is less common and can be disabling.
It usually affects nerves around the:
- Hip
- Buttock
- Thigh
Symptoms can include sudden or severe pain, weakness in the legs, difficulty standing from a seated position, muscle wasting, and sometimes weight loss. It commonly affects one side initially.
Unlike typical peripheral neuropathy, proximal neuropathy can have a different course and may gradually improve over months or years, although symptoms may not completely disappear.
Strength Training for Type 2 Diabetes
Early Signs of Diabetic Neuropathy
Early symptoms can be easy to overlook.
Watch for:
Feet
- Tingling
- Burning
- Numbness
- Pain
- Reduced sensation
- Feeling unusually cold or hot
- Sensitivity to bedsheets or light touch
Legs and hands
- Pins-and-needles sensations
- Shooting pain
- Weakness
- Loss of coordination
Balance
- Feeling unsteady
- Difficulty walking
- Increased falls
Autonomic symptoms
- Dizziness when standing
- Digestive changes
- Bladder problems
- Sexual dysfunction
- Abnormal sweating
The ADA notes that some peripheral neuropathy can be asymptomatic, meaning a person may have nerve damage without realizing it.
Can Diabetic Neuropathy Cause Foot Problems?
Yes.
Loss of protective sensation can make it difficult to notice minor injuries.
For example, you might not feel:
- A blister
- A cut
- A burn
- A pressure point from footwear
- A small object inside your shoe
If an injury goes unnoticed, it can progress to an ulcer or infection. Diabetes can make foot wounds more difficult to heal, increasing the risk of serious complications.
This is why daily foot awareness is an important part of diabetes care, particularly when neuropathy is present.
How Is Diabetic Neuropathy Diagnosed?
Diabetic neuropathy is primarily a clinical diagnosis, meaning a healthcare professional considers your symptoms, medical history, physical examination, and appropriate tests.
The 2026 ADA Standards recommend evaluating peripheral neuropathy using a combination of history and neurological tests. These can include assessment of:
- Temperature or pinprick sensation
- Vibration sensation
- Protective sensation
- Reflexes
- Foot condition
- Balance and gait
Annual 10-g monofilament testing is recommended to identify feet at risk of ulceration and amputation.
What Tests May Be Used?
Depending on your symptoms, your healthcare professional may use additional tests to investigate nerve damage or rule out other causes.
Possible tests include:
- Neurological examination
- Foot examination
- Monofilament testing
- Vibration testing
- Blood tests
- Nerve conduction studies
- Electromyography (EMG)
Blood tests may be used to look for conditions that can mimic or contribute to neuropathy, including vitamin B12 deficiency, thyroid problems, and kidney disease. Metformin use is one potential cause of low vitamin B12 levels.
This matters because not every case of neuropathy in a person with diabetes is necessarily caused by diabetes. The ADA describes diabetic neuropathy as a diagnosis of exclusion because other treatable neuropathies can occur in people who have diabetes.
How Is Diabetic Neuropathy Treated?
Treatment depends on the type of neuropathy and the symptoms.
There are several goals:
- Reduce the risk of further nerve damage
- Treat neuropathic pain
- Address underlying risk factors
- Prevent foot complications
- Improve mobility and quality of life
1. Manage Diabetes and Cardiovascular Risk Factors
Good diabetes management is an important part of protecting nerves.
Your healthcare team may focus on:
- Blood glucose management
- Blood pressure
- Cholesterol
- Weight management when appropriate
- Physical activity
- Smoking cessation
The 2026 ADA Standards recommend optimizing weight, blood pressure, and lipid management to reduce the risk or slow the progression of diabetic neuropathy.
Early and effective glucose management has strong evidence for delaying or preventing neuropathy in type 1 diabetes. In type 2 diabetes, the effect of glucose management is more modest, so addressing multiple risk factors is important.
2. Medicines for Neuropathic Pain
When diabetic neuropathy causes significant pain, healthcare professionals may prescribe medications specifically used for neuropathic pain.
The 2026 ADA Standards list several medication classes that may be used as initial treatments, including:
- Gabapentinoids
- Serotonin-norepinephrine reuptake inhibitors
- Tricyclic antidepressants
- Sodium channel blockers
Medication choice depends on the individual’s symptoms, age, other health conditions, potential side effects, and drug interactions.
Important
These medicines are intended to manage pain and symptoms. They do not necessarily repair already damaged nerves.
Do not start or stop prescription medication without discussing it with your healthcare professional.
3. Physical Therapy and Balance Training
If neuropathy causes weakness, balance problems, or difficulty walking, physical therapy may help.
A physical therapist may work on:
- Strength
- Balance
- Walking mechanics
- Mobility
- Fall prevention
NIDDK notes that physical therapy can be used to improve strength and balance in people with peripheral neuropathy.
4. Foot Care
Foot care becomes especially important when sensation is reduced.
Check your feet every day for:
- Cuts
- Blisters
- Redness
- Swelling
- Cracks
- Sores
- Changes in skin color
- Signs of infection
Wear properly fitting footwear and avoid walking barefoot if you have reduced sensation.
The ADA recommends regular foot assessment, including annual monofilament testing, while people with known foot problems may need more frequent professional evaluation.
Can Diabetic Neuropathy Be Reversed?
This is one of the most common questions.
Existing nerve damage generally cannot simply be reversed with one treatment.
The realistic treatment goals are to:
- Prevent or slow further nerve damage
- Improve symptoms
- Protect the feet
- Reduce complications
- Improve quality of life
For some types of neuropathy, symptoms can improve, particularly when an underlying cause is identified and treated. Proximal neuropathy, for example, may gradually improve over time.
This is different from claiming that diabetic neuropathy has a guaranteed cure.
Can Better Blood Sugar Control Stop Neuropathy?
Good glucose management can help prevent or delay diabetic nerve damage and may slow progression in some people.
However, better glucose control should not be presented as a guaranteed way to reverse established nerve damage.
The 2026 ADA Standards report strong prevention evidence in type 1 diabetes and more modest evidence for slowing progression in type 2 diabetes.
Your individualized glucose targets should come from your healthcare team.
Does Exercise Help Diabetic Neuropathy?
Physical activity is an important part of diabetes management and overall health.
Depending on your symptoms and physical abilities, a healthcare professional may recommend activities such as:
- Walking
- Cycling
- Swimming
- Strength training
- Balance exercises
If you have significant numbness, foot ulcers, severe pain, weakness, or balance problems, ask your healthcare professional which activities are safest before beginning a new exercise program.
Exercise should be individualized rather than treated as a universal cure for neuropathy.
Can Vitamins or Supplements Treat Diabetic Neuropathy?
Be cautious with supplements marketed as “nerve repair” or “neuropathy cures.”
There is no simple vitamin supplement that should replace appropriate diabetes management, evaluation, foot care, or evidence-based pain treatment.
If a healthcare professional suspects a nutritional deficiency—such as vitamin B12 deficiency—that deficiency should be evaluated and treated appropriately. NIDDK specifically notes that low B12 can be one potential contributor to neuropathy and that metformin can be associated with low B12.
Always discuss supplements with your healthcare professional, particularly if you take medications.
How Can You Prevent Diabetic Neuropathy?
If you have diabetes, prevention focuses on comprehensive diabetes management.
Key steps include:
1. Manage blood glucose
Follow your individualized diabetes treatment plan.
2. Monitor blood pressure
High blood pressure can contribute to vascular and nerve complications.
3. Manage cholesterol
Follow your healthcare professional’s recommendations for lipid management.
4. Stay physically active
Choose activities appropriate for your health and physical abilities.
5. Don’t smoke
Ask for evidence-based help if you want to quit.
6. Limit alcohol
Alcohol can contribute to nerve damage and may interact with diabetes management.
7. Check your feet daily
Look for injuries or skin changes.
8. Attend regular foot examinations
Don’t wait until you have pain—neuropathy can occur without obvious symptoms.
A Simple Daily Foot-Care Routine
If you have diabetes, especially if you have reduced sensation:
Morning
Check your feet before putting on socks and shoes.
Look for:
- Blisters
- Cuts
- Redness
- Swelling
- Cracked skin
During the day
Wear comfortable, properly fitting footwear.
Avoid walking barefoot when sensation is reduced.
Evening
Check your feet again, especially after outdoor activity or exercise.
If you cannot easily see the bottoms of your feet, use a mirror or ask someone you trust to help.
During medical visits
Make sure your healthcare professional knows about any:
- Numbness
- Burning
- Tingling
- Foot wounds
- Balance problems
- New pain
When Should You See a Doctor?
Contact a healthcare professional if you develop persistent:
- Tingling
- Burning
- Numbness
- Shooting pain
- Weakness
- Balance problems
- Changes in walking
- Loss of sensation
You should also report any foot wound or infection promptly, particularly if you have reduced sensation.
Seek urgent medical attention for a rapidly worsening foot infection, spreading redness or swelling, severe unexplained weakness, fainting, or other serious new symptoms.

Yes. Peripheral neuropathy can affect the hands and arms, although it commonly begins in the feet and legs.
Can diabetic neuropathy affect digestion?
Yes. Autonomic neuropathy can affect nerves controlling the digestive system and may cause gastrointestinal symptoms.
Can diabetic neuropathy affect the bladder?
Yes. Autonomic neuropathy can affect bladder function and may cause urinary problems.
Can diabetic neuropathy cause balance problems?
Yes. Damage involving larger sensory nerve fibers can cause loss of sensation, balance problems, and increased fall risk.
Why is foot care important with diabetic neuropathy?
Reduced sensation can make it difficult to notice cuts, blisters, burns, or pressure injuries. Early detection helps reduce the risk of serious foot complications.
How often should people with diabetes be checked for neuropathy?
The 2026 ADA Standards recommend assessment for diabetic peripheral neuropathy at type 2 diabetes diagnosis, five years after type 1 diabetes diagnosis, and at least annually thereafter.
Can vitamin B12 deficiency cause neuropathy?
Yes. Vitamin B12 deficiency can cause neurological problems and may need to be considered when evaluating neuropathy. Metformin is one possible contributor to low B12 levels.
What medicines are used for diabetic nerve pain?
Depending on the individual, healthcare professionals may use medications such as gabapentinoids, serotonin-norepinephrine reuptake inhibitors, tricyclic antidepressants, or sodium channel blockers.
Can exercise help diabetic neuropathy?
Exercise can support diabetes management, strength, mobility, and overall health. Physical therapy may also help people with neuropathy-related weakness or balance problems. The appropriate activity depends on the person’s symptoms and complications.
Conclusion
Diabetic neuropathy is a common diabetes complication that can affect sensation, movement, and the function of internal organs. Peripheral neuropathy most often affects the feet and legs and may cause burning, tingling, pain, numbness, weakness, or balance problems. Some people have little or no noticeable symptoms.
The most important steps are early recognition, regular neuropathy screening, comprehensive diabetes management, appropriate treatment of nerve pain, and consistent foot care.
If you have diabetes, don’t wait for severe pain before discussing nerve symptoms with your healthcare professional. Numbness can be an important warning sign because it may allow foot injuries to go unnoticed.
And while established nerve damage cannot always be reversed, appropriate treatment can help manage symptoms, protect your feet, reduce complications, and support quality of life.
