Do you experience tingling, burning, numbness or unusual sensations in your feet? These symptoms may sometimes be associated with diabetic peripheral neuropathy, a condition involving nerve damage related to diabetes.

Diabetic peripheral neuropathy commonly affects the nerves in the feet and legs. It can make walking, maintaining balance and performing everyday activities more challenging.

Some people experience persistent discomfort, while others may gradually lose sensation without noticing significant symptoms. Reduced sensation can also make it difficult to recognise minor foot injuries.

Understanding the condition and managing its contributing factors are important steps towards protecting your mobility and overall foot health.

If you or someone you care for is experiencing nerve-related symptoms, this guide explains the causes, warning signs and seven helpful management strategies.

What Is Diabetic Peripheral Neuropathy?

Diabetic peripheral neuropathy is a type of nerve damage associated with diabetes. It commonly affects the peripheral nerves responsible for carrying sensory and movement signals between the brain, spinal cord and the rest of the body.

The condition most frequently affects the feet and lower legs, although other areas can also be involved.

Peripheral nerves perform several important functions:

• Allowing you to feel touch, temperature and pain.

• Helping control muscle movements.

• Supporting coordination and balance.

• Communicating sensory information to the brain.

When these nerves become damaged, their ability to transmit signals can change.

Some people experience painful sensations, while others develop numbness or reduced protective sensation.

Not everyone with diabetic peripheral neuropathy experiences obvious symptoms, which makes regular diabetes-related foot and nerve assessments important.

Common Causes and Risk Factors of Diabetic Peripheral Neuropathy

Diabetic peripheral neuropathy is associated with prolonged exposure to elevated blood glucose levels and other metabolic factors.

Several factors may increase the risk of developing nerve damage.

1. Poorly Controlled Blood Glucose Levels

Persistently elevated blood glucose can contribute to nerve damage over time.

Managing blood glucose levels with guidance from your healthcare team is important for reducing the risk of developing or worsening diabetic complications.

2. Long Duration of Diabetes

The likelihood of developing diabetic neuropathy generally increases with the duration of diabetes.

Regular screening can help identify changes in nerve function before serious complications develop.

3. High Blood Pressure

High blood pressure can contribute to damage affecting blood vessels and increase the risk of diabetes-related complications.

Managing blood pressure is an important part of overall diabetes care.

4. High Cholesterol

Abnormal cholesterol levels may contribute to cardiovascular and circulation-related problems.

A healthcare professional can help assess and manage cholesterol alongside other diabetes-related risk factors.

5. Smoking

Smoking can negatively affect blood circulation and increase the risk of complications involving the feet and lower limbs.

Avoiding tobacco is an important part of protecting long-term health.

6. Other Medical Conditions

Not every nerve problem in someone with diabetes is necessarily caused by diabetes.

Other possible causes include:

• Vitamin B12 deficiency.

• Thyroid disorders.

• Kidney disease.

• Certain medications.

• Alcohol-related nerve damage.

• Other neurological conditions.

A medical assessment can help identify the underlying cause and determine appropriate treatment.

Common Symptoms of Diabetic Peripheral Neuropathy

Symptoms depend on which nerves are affected and the extent of nerve damage.

Common symptoms include:

• Tingling: A pins-and-needles sensation in the feet or legs.

• Burning pain: A burning or hot sensation, sometimes worse at night.

• Numbness: Reduced ability to feel touch or temperature.

• Sharp or shooting pain: Sudden nerve-related discomfort.

• Muscle weakness: Difficulty controlling certain foot or leg movements.

• Balance problems: Difficulty maintaining stability while standing or walking.

• Reduced sensation: Difficulty recognising pressure, injuries or changes in temperature.

Some people experience symptoms in both feet, often beginning in the toes and gradually spreading upwards.

Reduced protective sensation is particularly important because small injuries may go unnoticed.

7 Helpful Ways to Manage Diabetic Peripheral Neuropathy

Managing diabetic peripheral neuropathy involves protecting nerve and foot health, maintaining suitable physical activity and addressing underlying risk factors.

The following strategies may help support daily function and reduce the risk of complications.

1. Monitor Your Blood Glucose Levels

Managing blood glucose is an important part of diabetes care.

Work with your GP or diabetes specialist to establish an appropriate management plan.

This may include:

• Following your prescribed medication plan.

• Monitoring blood glucose as recommended.

• Attending regular diabetes reviews.

• Following suitable dietary advice.

• Discussing changes in symptoms with your healthcare team.

Good glucose management can help prevent or delay nerve damage and may slow its progression, although it does not reverse existing nerve damage.

2. Check Your Feet Every Day

Reduced sensation can make it difficult to notice cuts, blisters and other injuries.

Daily foot checks can help identify problems early.

Look for:

• Cuts or scratches.

• Blisters.

• Redness.

• Swelling.

• Skin cracks.

• Changes in skin colour.

• Unusual warmth.

• Signs of infection.

Check the soles of your feet and the areas between your toes.

If you cannot easily see your feet, consider using a mirror or asking someone to help.

Seek prompt medical attention if you notice an ulcer, open wound, unusual swelling, redness or signs of infection.

3. Choose Appropriate Footwear

Suitable footwear helps protect your feet from pressure, friction and accidental injuries.

Consider the following:

• Wear comfortable, well-fitting shoes.

• Avoid footwear that causes rubbing.

• Check inside your shoes before wearing them.

• Avoid walking barefoot.

• Choose socks without uncomfortable seams.

• Have your footwear assessed if you have foot deformities or a history of ulcers.

If you have reduced protective sensation or previous foot complications, ask your healthcare team whether specialised footwear is appropriate.

4. Maintain Safe Physical Activity

Regular physical activity can support general health, mobility, cardiovascular fitness and physical function.

Depending on your medical condition and foot health, suitable activities may include:

• Walking.

• Stationary cycling.

• Swimming.

• Gentle strengthening exercises.

• Supervised balance activities.

Exercise should be selected according to your sensation, balance, circulation and existing foot problems.

People with foot ulcers, active wounds or significant foot complications may need to avoid weight-bearing exercise until medically assessed.

5. Improve Balance and Coordination

Nerve damage can affect the sensory information needed to maintain balance.

Some people may experience difficulty walking on uneven surfaces or standing for extended periods.

A suitable rehabilitation programme may include:

• Supported standing exercises.

• Controlled weight shifting.

• Sit-to-stand practice.

• Lower-limb strengthening.

• Walking practice.

• Functional balance exercises.

Balance exercises should be performed in a safe environment with appropriate support.

If you have significant numbness, weakness or a history of falls, seek professional guidance before starting a balance programme.

6. Strengthen Your Lower-Limb Muscles

Muscle weakness can affect walking, standing and everyday movement.

A physiotherapist may recommend exercises targeting the muscles of the hips, thighs, calves and feet.

Depending on your assessment, exercises may include:

• Seated knee extensions.

• Supported sit-to-stand exercises.

• Seated ankle movements.

• Resistance-band exercises.

• Supported heel raises, if appropriate.

• Gentle lower-limb strengthening.

Exercise intensity should be adjusted according to your strength, sensation and foot condition.

The goal is to maintain functional strength and support comfortable movement.

7. Attend Regular Medical and Foot Assessments

Diabetic peripheral neuropathy can sometimes develop without obvious symptoms.

Regular assessments help identify changes in sensation, circulation and foot health.

Your healthcare team may recommend:

• Regular diabetes reviews.

• Annual neuropathy screening or more frequent assessments when indicated.

• Foot sensation testing.

• Circulation checks.

• Podiatry appointments.

• Medication reviews.

• Physiotherapy when mobility or strength is affected.

Early identification of problems can help reduce the risk of preventable foot complications.

How Is Diabetic Peripheral Neuropathy Diagnosed?

Diagnosis usually involves reviewing your medical history, symptoms and clinical examination findings.

A doctor may ask:

• How long have you had diabetes?

• Do you experience burning or tingling in your feet?

• Have you noticed numbness?

• Do you experience balance difficulties?

• Have you developed foot wounds or injuries?

• Are your symptoms affecting both feet?

Clinical Examination

A healthcare professional may assess:

• Sensation in the feet.

• Temperature and pain perception.

• Vibration sensation.

• Muscle strength.

• Tendon reflexes.

• Walking and balance.

• Protective sensation.

A 10-g monofilament test may be used to assess protective sensation and identify feet at increased risk of injury.

Additional Investigations

Further investigations may be recommended depending on your symptoms and medical history.

These may include:

Blood Tests: May help assess blood glucose control, vitamin B12 levels, thyroid function and other possible causes of nerve symptoms.

Nerve Conduction Studies: May be used when the diagnosis is unclear or another neurological condition is suspected.

Electromyography (EMG): May help assess electrical activity in muscles and identify certain nerve or muscle disorders.

Not everyone requires these investigations. The choice depends on the clinical assessment.

How Can Physiotherapy Help With Diabetic Peripheral Neuropathy?

Physiotherapy may help people experiencing diabetic peripheral neuropathy by addressing physical limitations associated with weakness, reduced balance and difficulty walking.

It is important to understand that physiotherapy does not reverse established nerve damage. Instead, rehabilitation focuses on improving functional ability, mobility and safety.

1. Improving Lower-Limb Strength

A physiotherapist can assess muscle weakness and develop an appropriate strengthening programme.

Exercises may target the muscles needed for walking, standing and daily activities.

2. Improving Balance

Reduced sensation can affect balance and increase the risk of falls.

Physiotherapy may include supported balance training and functional movement exercises.

3. Supporting Walking Ability

Walking assessments can help identify movement difficulties and the need for suitable modifications or walking aids.

4. Improving Physical Confidence

A supervised exercise programme may help people feel more confident performing everyday activities.

5. Developing a Personalised Exercise Plan

Exercise recommendations should consider:

• Foot sensation.

• Circulation.

• Existing wounds.

• Balance ability.

• Other medical conditions.

A personalised programme helps ensure that activities are appropriate for the individual’s needs.

How Long Does Diabetic Peripheral Neuropathy Take to Improve?

Diabetic peripheral neuropathy is often a long-term condition.

The recovery outlook depends on the extent of nerve damage, the underlying cause and the effectiveness of ongoing medical management.

Some people may experience improvement in symptoms when contributing factors are addressed. However, established nerve damage may not fully reverse.

Management focuses on:

• Maintaining appropriate blood glucose levels.

• Controlling blood pressure and cholesterol.

• Preventing foot injuries.

• Managing nerve-related pain.

• Maintaining muscle strength.

• Improving balance and mobility.

• Reducing the risk of falls and ulcers.

Regular follow-up with your healthcare team is important.

Diabetic Peripheral Neuropathy vs Peripheral Artery Disease: What Is the Difference?

Both conditions can affect the feet and lower legs, but they involve different body systems.

Both conditions can occur together in people with diabetes.

A healthcare professional can assess whether nerve damage, circulation problems or a combination of conditions is contributing to your symptoms.

When Should You Seek Medical Advice?

Seek medical assessment if you experience:

• New or increasing numbness.

• Persistent burning or tingling.

• Muscle weakness.

• Difficulty maintaining balance.

• Changes in walking ability.

• A foot wound that is not healing.
