Neuropathy is when your nerves are damaged or not working right. It often affects the peripheral nerves. These nerves link the brain and spinal cord to the body. You might feel numbness, weakness, and pain in your hands and feet. Causes range from diabetes to autoimmune disorders and more. Learning about neuropathy helps in its recognition, diagnosis, and treatment.

Understanding Peripheral Neuropathy

Peripheral neuropathy is a problem that affects the nerves outside the brain and spinal cord. These nerves send and receive messages from the brain to the body. It includes nerves that control muscles, feel sensations, and manage body functions automatically. The signs of peripheral neuropathy change based on the kind of nerves involved and the cause of the problem.

Types of Peripheral Nerves

The peripheral nervous system has three main types of nerves:

  1. Motor nerves: They carry messages from the brain to the muscles. This helps with movement and muscle action.
  2. Sensory nerves: They send feelings like touch, heat, and pain from the body to the central nervous system.
  3. Autonomic nerves: They handle involuntary actions in the body, like heart rate, blood pressure, digestion, and sweat production.

Issues with these nerve types can cause the symptoms and problems linked to peripheral neuropathy.

Common Symptoms of Neuropathy

Peripheral neuropathy leads to a wide range of symptoms. These symptoms differ based on the damaged nerves. It’s key to know the types of nerve damage and their symptoms. This helps in dealing with the condition effectively.

Sensory Nerve Symptoms

With sensory nerve damage, you may feel numbness or tingling. This often happens in the hands, feet, or other body parts. You might also lose feeling in those areas or feel sharp, jabbing, or burning pain. Some people become extremely sensitive to touch or changes in temperature.

Motor Nerve Symptoms

Motor nerve damage can cause muscle weakness or loss of muscle tone. Lack of coordination and a higher risk of falling are also common. Moving the affected muscles or limbs might become hard.

Autonomic Nerve Symptoms

Damaged autonomic nerves show different symptoms. These include not handling heat well, or sweating too much or too little. Some people experience digestive issues like constipation or diarrhea. They may also feel dizzy due to low blood pressure.

Causes of Peripheral Neuropathy

Peripheral neuropathy has many causes. It can be due to autoimmune diseases or metabolic disorders. Infections, inherited conditions, and even exposure to toxins can also lead to it. It’s important to know these causes for the right diagnosis and treatment.

Autoimmune Diseases

Autoimmune diseases make the immune system attack the body. This can cause peripheral neuropathy. Sjogren’s syndrome, lupus, and rheumatoid arthritis are some autoimmune diseases. They can lead to neuropathy. So can conditions like Guillain-Barré syndrome and paraneoplastic syndrome, which are related to certain cancers.

Diabetes and Metabolic Syndrome

Diabetes, especially when blood sugar isn’t controlled well, is a big cause of peripheral neuropathy. This condition can also be linked to metabolic syndrome. Metabolic syndrome includes high blood sugar, blood pressure, and obesity.


Infections by certain viruses and bacteria can damage the peripheral nerves. For example, Lyme disease and shingles can lead to neuropathy. So can hepatitis B and C, HIV, and leprosy.

Inherited Disorders

Some people inherit the risk of peripheral neuropathy. Charcot-Marie-Tooth disease runs in families. It’s a group of disorders affecting the peripheral nerves.

Tumors and Bone Marrow Disorders

Tumors, both cancerous and non-cancerous, and bone marrow disorders may press on nerves or damage them. Monoclonal gammopathies and amyloidosis, for example, are such conditions.

Other Diseases and Conditions

Certain other diseases can also cause peripheral neuropathy. These include kidney disease, liver disease, and an underactive thyroid (hypothyroidism).

Exposure to Toxins and Medications

Some chemicals and toxins can harm the nerves. This can include industrial chemicals and heavy metals like lead and mercury. Also, some medications, especially some chemotherapy drugs, list neuropathy as a side effect.

Injury or Nerve Compression

Physical injuries from accidents or falls can hurt the nerves. Even activities like sports can be a cause. Nerve compression, which happens in carpal tunnel syndrome, can also bring on neuropathy.

Vitamin Deficiencies

Not getting enough certain vitamins and minerals can hurt your nerves. Deficiencies in B vitamins (like B1, B6, B12), copper, and vitamin E can lead to peripheral neuropathy.

Risk Factors for Neuropathy

Many factors can raise the chances of getting peripheral neuropathy. These include:

  • Diabetes, especially with poor blood sugar control
  • Alcohol misuse
  • Low levels of vitamins, particularly B vitamins
  • Infections, such as Lyme disease, shingles, hepatitis, and HIV
  • Autoimmune diseases like rheumatoid arthritis and lupus
  • Kidney, liver, or thyroid disorders
  • Exposure to toxins and chemicals
  • Repetitive motions, such as those performed in certain jobs
  • Family history of neuropathy

Complications of Peripheral Neuropathy

Without treatment, peripheral neuropathy can cause serious problems. These include skin injuries, burns, and wounds, often on the feet. People may not feel these injuries and end up with infections.

Falls and balance issues are also common. This comes from weaker muscles and loss of feeling. This is especially risky for those with diabetes. It’s crucial to manage and prevent peripheral neuropathy.

Diabetic foot ulcers are a major issue with this condition. It happens because high blood sugar harms blood vessels. This cuts off blood supply to the feet, slowing wound healing and raising the risk of gangrene.

Another problem is cardiovascular autonomic neuropathy (CAN). It can make exercise hard and cause low blood pressure. This can lead to dizziness or even faints. Steps to combat low blood pressure include standing up slowly and drinking more fluids. Wearing compression stockings and taking certain drugs like fludrocortisone and midodrine can also help.

Heart arrhythmias and, in the worst case, cardiac arrest can happen due to CAN. Doctors may prescribe medications like flecainide to help manage these heart problems. It’s vital for people with CAN to regularly check their heart health. This can help doctors treat any issues quickly and effectively.

Preventing Peripheral Neuropathy

The best way to stop peripheral neuropathy is by handling the health problems that start it. This means keeping your blood sugar level right if you have diabetes. It also means treating autoimmune diseases and infections linked to nerve damage.

Managing Underlying Conditions

If you have diabetes, it’s crucial to keep your blood sugar levels in check. Over half of diabetes patients face some neuropathy. Keeping diabetes under control helps avoid or slow down nerve damage.

Problems like Sjogren’s, lupus, and rheumatoid arthritis can also trigger neuropathy. You can reduce the risk by treating these diseases with medications or other treatments.

Some infections, like Lyme disease and HIV, can harm your nerves. If you catch these early and treat them fast, it can help prevent neuropathy.

Adopting Healthy Lifestyle Habits

Stay healthy by eating right and exercising. This helps protect your nerves. And avoid things that can hurt your nerves, like toxic chemicals and too much alcohol.

By managing your health and life choices, you lower the risk of peripheral neuropathy. This also cuts down on its related problems.

What is neuropathy

Neuropathy is a broad term for issues with peripheral nerves, which are outside the brain and spinal cord. It causes symptoms like numbness, tingling, weakness, and pain, especially in the hands and feet. Various things, like diabetes, autoimmune diseases, infections, and even vitamin shortages can trigger neuropathy. So, knowing what neuropathy is helps in spotting, diagnosing, and treating it.

Diagnosis and Evaluation

To diagnose peripheral neuropathy, doctors start with a detailed medical history and a physical exam. They ask about symptoms, medical conditions, things you’ve been exposed to, and family disease history. This helps find out the possible reasons for the neuropathy.

Medical History and Physical Examination

In the medical history, you’ll talk about where, how bad, and how it changes your numbness or pain. Doctors also look into your medical past, lifestyle, anything toxic you’ve encountered, how much you drink, and if your family has nerve diseases.

Next, the physical exam checks things like your tendon reflexes, how strong your muscles are, and if you feel things as you should. It also looks at your balance and coordination, key in diagnosing neuropathy.

Laboratory Tests

Doctors might order many lab tests to figure out peripheral neuropathy. They check your blood for vitamin shortages, autoimmune problems, and infections. And they look at your liver, kidneys, and thyroid.

Your urine might be tested for Bence-Jones proteins, a sign of multiple myeloma.

Nerve Conduction Studies and Electromyography

Nerve conduction studies and electromyography (EMG) are special tests that doctors might do. These tests show how your peripheral nerves are working. They help find out what’s wrong and how bad it is.

Imaging Tests

In some situations, imaging tests like MRIs or CT scans are needed. These look for things like compressed nerves, tumors, or other issues in your body. They’re important as they show hidden problems.

Nerve Biopsy and Genetic Testing

Sometimes, for very challenging cases, a nerve biopsy or genetic test is done. This is more for rare or inherited forms of neuropathy. These tests are crucial for finding the exact cause.

Treatment and Management Strategies

The main goal of treating peripheral neuropathy is to deal with its main cause, if we can. Steps may include:

  • Keeping blood sugar in check for those with diabetes
  • Using drugs or therapies to fight autoimmune issues
  • Treating any infections beneath the surface

Medications for Symptom Relief

Besides the root cause, doctors might give medications to ease peripheral neuropathy symptoms. These can include:

  • Medicines for pain, like certain antidepressants and anti-seizure drugs
  • Creams or ointments for pain in certain spots

Physical and Occupational Therapy

Physical and occupational therapy is key to peripheral neuropathy management. It aims to help patients:

  • Better their muscle strength and coordination
  • Improve balance and avoid tumbles
  • Master skills to handle symptoms and keep doing daily tasks alone

Pain Management

For those with ongoing pain from peripheral neuropathy, docs might suggest pain relief methods. These can be:

  • Drugs to ease the pain
  • Scrambler therapy, an alternative method. It uses electrical pulses to lower chronic pain levels


Peripheral neuropathy is a serious issue that challenges life quality. It’s vital for both doctors and patients to know the causes, symptoms, and how to diagnose and treat it. This knowledge helps in spotting the disease early and dealing with it the right way.

It affects about 2.4% of the world and reaches 8% in the elderly, making it a big health issue. Causes like diabetes, infections, and genetic disorders signal the need for careful check-ups and specific treatments.

Keeping up with the latest neuropathy info is important for healthcare workers and patients. It aids in success in dealing with this complex illness. By working together, they can make real improvements in life quality and reduce the impact of this severe disorder.
