Diabetic Neuropathy in Feet: Symptoms, Causes, and Treatment Options

Diabetic neuropathy is a common complication of diabetes, affecting nerves in various parts of the body, with the feet being particularly vulnerable. This type of nerve damage happens when prolonged high blood sugar levels cause injury to nerve fibers. Although diabetic neuropathy can occur in different forms, the most prevalent type is peripheral neuropathy, which predominantly impacts the nerves in the legs and feet.

The symptoms of diabetic neuropathy in the feet can range from mild tingling and numbness to more severe effects, such as burning pain or even paralysis. Experiencing these symptoms can greatly impact an individual's quality of life, making it difficult to walk, maintain balance or even recognize potentially dangerous wounds or infections. It is crucial for people with diabetes to maintain vigilant foot care and consistently regulate their blood sugar levels as a means to prevent or slow down the progression of neuropathy.

Treatment options for diabetic neuropathy in the feet mainly focus on relieving pain, managing associated complications, and restoring function. While there is no known cure, effective management can provide a significant improvement in symptoms and help patients maintain a better life quality. Early diagnosis and intervention remain vital to achieving the best possible outcome for those affected by this condition.

Causes of Diabetic Neuropathy

Diabetic neuropathy is a type of nerve damage that occurs in people with diabetes. High blood sugar levels can damage nerve fibers throughout the body, but diabetic neuropathy most often affects nerves and blood vessels in the legs and feet, leading to pain and numbness.

One of the primary causes of diabetic neuropathy is prolonged exposure to high blood glucose levels. Over time, high blood sugar levels and high levels of fats, such as triglycerides, can damage the nerves and the small blood vessels that nourish them with oxygen and nutrients.

In addition to high blood sugar, there are several other factors that may contribute to the development of diabetic neuropathy. These include:

  • Smoking: Smoking can constrict blood vessels and reduce blood flow to the nerves, which can exacerbate nerve damage.

  • High blood pressure: Elevated blood pressure can also cause damage to the blood vessels that supply the nerves, further contributing to neuropathy.

  • High cholesterol: Elevated cholesterol levels can lead to a buildup of plaque in the blood vessels, which can impede blood flow and nutrient delivery to the nerves.

To mitigate the risk of developing diabetic neuropathy, it is important for individuals with diabetes to maintain optimal blood sugar levels, reduce smoking, manage blood pressure, and control cholesterol levels. By addressing these risk factors, the likelihood of developing neuropathic complications can be reduced, preserving the health of the nerves and blood vessels in the feet and legs.

Symptoms and Types of Neuropathy

Diabetic neuropathy can present in various forms, depending on the type of nerves affected. This section will discuss the different types of neuropathy, along with their associated symptoms.

Peripheral Neuropathy

Peripheral neuropathy is the most common form of diabetic neuropathy, mainly affecting the hands, legs, and feet. The symptoms of peripheral neuropathy include:

  • Numbness or tingling in the affected areas, often first noticed in the feet or legs
  • Pain ranging from mild discomfort to burning or shooting sensations
  • Loss of balance or coordination

In more severe cases, poor blood oxygen levels due to peripheral neuropathy can result in foot ulcers, leading to severe complications if not properly treated. source

Autonomic Neuropathy

Autonomic neuropathy affects the nerves that control your organs, causing problems with the digestive system, urinary tract, blood vessels, and heart. These symptoms can vary depending on the specific nerves impacted. source

Proximal Neuropathy

Proximal neuropathy primarily affects the hips, thighs, and buttocks, and symptoms may include:

  • Weakness in the affected areas
  • Pain in the lower back or hips, which may be accompanied by tingling or numbness
  • Difficulty standing up from a seated position


Focal Neuropathy

Focal neuropathy, also known as mononeuropathy, involves damage to a single nerve that results in localized symptoms. These can vary depending on the affected nerve, but may include:

  • Sudden, severe pain in the area served by the damaged nerve (e.g., hand or leg)
  • Issues with coordination or difficulty lifting objects
  • Loss of sensation in the affected area
  • Muscle weakness or paralysis of the associated body part


Risk Factors and Prevention

Diabetic neuropathy, a common complication of diabetes, affects the nerves in the body and can specifically target the feet. It is essential to identify the risk factors and take preventive measures to effectively manage diabetic neuropathy in the feet.

Risk Factors

Several factors increase the risk of developing diabetic neuropathy, including:

  • High blood sugar levels: Poor control of blood sugar levels in people with type 2 diabetes can lead to nerve damage.
  • Kidney disease: Diabetes-related kidney disease can contribute to neuropathy by affecting the nerves and blood vessels.
  • Overweight: Individuals with a body mass index (BMI) of 25 or more are at a higher risk of developing diabetic neuropathy.
  • Smoking: Smoking narrows and hardens the arteries, reducing blood flow to the legs and feet. This makes it more difficult for wounds to heal and damages the peripheral nerves.
  • Heart disease and blood pressure: Uncontrolled blood pressure and heart disease increase the risk of nerve damage in diabetic individuals.
  • High cholesterol and triglycerides: These can contribute to the development of diabetic neuropathy by causing inflammation and damaging blood vessels.


To reduce the risk of developing diabetic neuropathy and manage its symptoms, consider the following preventive measures:

  • Control blood sugar levels: Maintaining optimal blood sugar levels is vital in preventing diabetic neuropathy. Regular monitoring and following the prescribed diabetes management plan are crucial.
  • Physical activity: Engaging in daily aerobic exercises can protect nerves and improve neuropathy outcomes. Consult a healthcare professional before beginning any exercise program.
  • Maintaining a healthy weight: Losing weight, if obese or overweight, can help reduce the risk of diabetic neuropathy.
  • Quit smoking: Stopping smoking can improve blood flow to the legs and feet, preventing further damage to the peripheral nerves.
  • Manage blood pressure and heart health: Regular check-ups and following the prescribed treatment plan for high blood pressure and heart disease can reduce the risk of neuropathy.
  • Control cholesterol and triglycerides: Proper diet and medication, if necessary, can help manage cholesterol and triglyceride levels, reducing the risk of nerve damage.

In conclusion, understanding the risk factors and taking preventive measures are crucial for managing diabetic neuropathy in the feet. Regular check-ups, maintaining overall health, and following a diabetes management plan can help prevent complications and improve quality of life for those living with diabetes.

Diagnosis and Screening

Diagnosing diabetic neuropathy in feet involves a combination of a physical examination, a review of symptoms and medical history, and additional tests as needed. A healthcare provider typically checks the patient's overall muscle strength and tone as well as tendon reflexes to detect any potential neuropathy signs1.

Before any physical tests are done, your doctor will review your medical history and enquire about symptoms you might be experiencing. Early symptoms of diabetic peripheral neuropathy often occur in the toes and fingertips, expanding proximally over time in a stocking-and-glove pattern. Sensations to stimuli such as vibration, pinprick, temperature, and monofilament testing tend to diminish in this same pattern2.

Initial testing for diabetic neuropathy usually includes:

  • Complete blood count
  • Comprehensive metabolic profile
  • Fasting blood glucose
  • Thyroid-stimulating hormone3

These tests help the doctor identify underlying causes or contributing factors, such as uncontrolled blood glucose levels, which may lead to neuropathy.

Foot exams are also essential in the screening process for diabetic neuropathy. Your doctor will examine your feet for any cuts, sores, or blisters that may be present. They will also perform tests to check for loss of sensation in the feet, such as monofilament testing, which involves gently pressing a thin nylon wire against various points on the foot4.

Screening and early identification of neuropathic processes provide a crucial opportunity for diabetic patients to actively alter their course of suboptimal glycemic control and implement improved foot care before the onset of significant morbidity5.

In summary, diagnosing diabetic neuropathy in feet involves a combination of physical examinations, medical history reviews, and blood tests to identify underlying causes. Foot exams and monitoring of blood glucose levels play a vital role in early detection and management of neuropathy.


Diabetic neuropathy is a common complication of diabetes that affects the nerves, particularly in the feet. This condition can lead to various other complications, impacting the blood vessels, heart, kidney, digestive system, urinary tract, and more.

One of the most common complications of diabetic neuropathy is the loss of sensation in the feet. This numbness can make it difficult for patients to feel pain, temperature changes, or even a pebble in their shoe, which may result in unnoticed cuts and sores. If left untreated, these sores can become infected and lead to more severe complications.

Another issue caused by diabetic neuropathy is the development of foot ulcers. Due to the combination of reduced sensation and compromised blood vessels, ulcers can form in areas exposed to pressure or injury. These ulcers can easily become infected, and if left untreated or poorly managed, they can lead to the need for amputation of the affected toe, foot, or leg.

Apart from complications affecting the feet, diabetic neuropathy may also lead to:

  • Gastroparesis: Neuropathy affecting the digestive system can cause this condition, where the stomach takes too long to empty its contents. Symptoms include nausea, indigestion, and vomiting. Gastroparesis can further complicate diabetes management by affecting blood sugar levels.

  • Diabetic amyotrophy: This rare form of neuropathy affects the nerves in the hips, thighs, or buttocks, causing severe, sudden pain followed by muscle weakness and wasting.

  • Kidney disease: Diabetic neuropathy can contribute to kidney disease or nephropathy, as it affects the nerves in the kidney that helps maintain proper function.

  • Urinary tract problems: Nerve damage to the urinary tract can result in issues such as incontinence, urinary retention or frequent urinary infections.

  • Heart complications: Autonomic neuropathy can cause irregular heartbeats or even heart attack, as it affects the nerves that control the heart and blood vessels.

It is important for individuals with diabetes to manage their blood sugar levels and seek professional healthcare advice for early detection and treatment of diabetic neuropathy, to minimize the risk of these complications.

Treatment and Management

Diabetic neuropathy in feet can be managed through a combination of lifestyle changes and medications. The main goals of treatment are to slow the progression of the disease, relieve pain, manage complications, and restore function.


Pain relief for diabetic neuropathy can be achieved through the use of various medications. These include:

  • Over-the-counter pain relievers such as ibuprofen or acetaminophen
  • Prescription medications like anticonvulsants or antidepressants to manage nerve pain
  • Topical creams or patches with active ingredients like lidocaine or capsaicin

Lifestyle Changes

In addition to medication, making certain lifestyle changes can help alleviate symptoms and slow the progression of diabetic neuropathy. Key changes include:

  • Exercise: Engaging in regular physical activity, such as walking or gentle routines like yoga and tai chi, can improve muscle strength, reduce neuropathy pain, and control blood sugar levels.
  • Quit smoking: Smoking negatively affects circulation and increases the risk of foot problems and other neuropathy complications. Quitting smoking is essential for better management.
  • Weight loss: Maintaining a healthy weight can help control blood sugar levels and reduce the risk of developing further complications.
  • Nutrients: Eating a balanced diet rich in essential nutrients supports overall health and helps manage blood sugar levels.

Foot Care and Sensitivity to Touch

Proper foot care is crucial for individuals with diabetic neuropathy in feet, as it helps prevent and manage complications. Implementing the following habits can make a significant difference:

  • Inspect feet daily for wounds, injuries, or potential infections
  • Keep feet clean and dry
  • Wear comfortable, well-fitting shoes and socks
  • Avoid walking barefoot
  • Trim toenails regularly and carefully

For those dealing with sensitivity to touch, consulting a healthcare professional about therapy options may be helpful. Some individuals have found relief with methods like transcutaneous electrical nerve stimulation (TENS), which uses a mild electrical current to alleviate pain.

Incorporating these treatments and management strategies can significantly impact the quality of life for individuals with diabetic neuropathy in feet. Consulting with a healthcare professional is crucial for creating a personalized treatment plan that suits individual needs and addresses specific symptoms.

Lifestyle and Support

Managing diabetic neuropathy in feet involves a combination of lifestyle changes and support strategies. One crucial factor is maintaining a healthy body mass index (BMI), which can be achieved by following a balanced diet and engaging in regular exercise. A well-balanced diet is vital to control blood sugar levels and prevent the progression of neuropathy.

Regular exercise not only helps in maintaining a healthy weight but also improves blood circulation, particularly in the extremities. Engaging in physical activities like walking, swimming, or cycling can help prevent complications of diabetic neuropathy such as peripheral artery disease, which can lead to further impairment or even amputations if left untreated.

People with diabetic neuropathy should pay special attention to their feet, as they may experience chronic pain and reduced sensations. One helpful approach is to participate in a support group, where individuals can share their experiences, coping strategies, and tips on living with neuropathy. Support groups can provide emotional encouragement and help patients navigate the challenges of living with this condition.

In conclusion, for individuals suffering from diabetic neuropathy in feet, a combination of a healthy lifestyle and supportive strategies can effectively manage symptoms and prevent complications. By taking a proactive approach and working closely with healthcare professionals, patients can maintain a good quality of life despite this condition.

Diabetic neuropathy is a type of nerve damage that can occur in individuals with diabetes, most often affecting nerves in the legs and feet. Mayo Clinic provides an overview of the symptoms and causes associated with this condition. High blood sugar levels can lead to nerve injury throughout the body, resulting in pain, numbness, and other symptoms in the affected areas.

The most common type of focal neuropathy associated with diabetes is carpal tunnel syndrome, which involves nerve compression in the wrist. According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), less than 10% of people with diabetes experience carpal tunnel syndrome symptoms, but about 25% have some degree of nerve compression at the wrist.

To diagnose peripheral neuropathy, doctors rely on a combination of a patient's symptoms, family and medical history, physical exam, and tests. NIDDK states that patients with diabetes should undergo a thorough examination to assess any sensations in their feet and legs at least once a year.

There are several types of diabetes-related neuropathy, as mentioned by the Cleveland Clinic. These include:

  • Autonomic neuropathy: Damage to nerves that control your organs
  • Mononeuropathy: Damage to a single nerve, such as in your hand or leg
  • Peripheral neuropathy: Most commonly affects your feet and legs and sometimes affects the hands
  • Proximal neuropathy: Leads to weakness in hips, thighs, buttocks

Peripheral neuropathy affects 25% to 50% of patients with diabetes, depending on factors such as patient's age, the number of years with diabetes, and the level of diabetes control.
