Neuropathy, also known as peripheral neuropathy, is a condition that affects the peripheral nervous system, which consists of the nerves outside of the brain and spinal cord. It occurs when there is damage or dysfunction to these peripheral nerves, leading to a variety of symptoms.
The peripheral nerves are responsible for transmitting signals between the central nervous system (the brain and spinal cord) and the rest of the body, including the muscles, organs, and sensory receptors. They play a crucial role in motor function, sensation, and autonomic functions (such as heart rate and digestion).
Neuropathy can affect a single nerve (mononeuropathy) or multiple nerves (polyneuropathy). It can also be categorized based on the specific types of nerves affected, such as sensory, motor, or autonomic nerves. The most common form of neuropathy is peripheral polyneuropathy, which involves damage to multiple peripheral nerves. Let's explore causes, symptoms, treatments, and the essential nutrients needed for helping defeat neuropathy.
Causes of Neuropathy: Neuropathy can have various causes, including:
Diabetes: High blood sugar levels can damage the nerves over time, leading to diabetic neuropathy.
Trauma: Injuries, accidents, or repetitive stress on nerves can result in nerve damage.
Infections: Certain infections, such as Lyme disease, shingles, and HIV/AIDS, can cause neuropathy.
Autoimmune Diseases: Conditions like rheumatoid arthritis, lupus, and Guillain-Barré syndrome can lead to nerve damage.
Nutritional Deficiencies: Deficiencies in vitamins (especially B vitamins), minerals (such as magnesium), and other nutrients can contribute to neuropathy.
Toxic Exposures: Exposure to toxins like heavy metals, certain medications, and chemotherapy drugs can damage nerves.
Genetic Predisposition: Some individuals may have inherited genetic mutations that make them more susceptible to neuropathy.
Food Intolerance: Consuming foods that contain ingredients that individuals are intolerant to, such as gluten found in wheat, can put them at a higher risk of developing neuropathy.
Symptoms of Neuropathy:
The symptoms of neuropathy can vary depending on the type and location of the affected nerves. Common symptoms include:
- Numbness or tingling sensations in the hands, feet, or other affected areas.
- Sharp or burning pain.
- Muscle weakness or loss of coordination.
- Sensitivity to touch or temperature changes.
- Loss of reflexes.
- Balance problems.
- Digestive issues.
- Changes in blood pressure or heart rate.
There are several treatment options available for neuropathy, depending on the underlying cause and the specific symptoms experienced by the individual. Here are some common treatments for neuropathy:
- Pain relievers: Over-the-counter medications like acetaminophen or nonsteroidal anti-inflammatory drugs (NSAIDs) can help manage mild to moderate pain.
- Prescription medications: Certain medications, such as anticonvulsants (e.g., gabapentin, pregabalin), antidepressants (e.g., amitriptyline, duloxetine), and opioids (e.g., tramadol), may be prescribed to alleviate neuropathic pain.
- Topical treatments: Medications like lidocaine patches or capsaicin creams can provide localized pain relief.
- Exercise programs: Engaging in regular physical activity and specific exercises can help improve muscle strength, balance, and coordination, which can alleviate neuropathy-related symptoms.
- Transcutaneous electrical nerve stimulation (TENS): TENS therapy involves the use of low-voltage electrical currents delivered through electrodes placed on the skin to provide pain relief and improve nerve function.
- Spinal cord stimulation: In some cases of chronic neuropathic pain, a spinal cord stimulator device is surgically implanted to deliver electrical signals to the spinal cord, helping to reduce pain signals.
- Peripheral nerve stimulation: Similar to spinal cord stimulation, this involves implanting a device near the affected peripheral nerve to deliver electrical impulses that block pain signals.
- Maintaining a healthy diet: A balanced diet rich in essential nutrients, especially B vitamins, can support nerve health.
- Elimination inflammatory foods: Removing foods that your immune system is intolerant to or that you have allergies to is essential for managing neuropathy. It's worth noting that gluten intolerance, in particular, has been identified as a potential cause of idiopathic neuropathy.
- Managing underlying conditions: Effective management of conditions like diabetes, autoimmune diseases, or infections can help prevent or slow down the progression of neuropathy.
- Pain management techniques: Techniques such as relaxation exercises, meditation, and biofeedback may help individuals cope with neuropathic pain.
- Acupuncture: The insertion of thin needles into specific points on the body may provide pain relief and improve nerve function in some individuals.
- Herbal remedies: Certain herbal supplements, such as alpha-lipoic acid or evening primrose oil, have shown potential in reducing neuropathic pain, but further research is needed.

It is important to consult with a healthcare professional to determine the most appropriate treatment plan based on individual needs and the underlying cause of neuropathy.
Nutritional Supplements for Reducing Neuropathy
While medical and/ or a combination of alternative treatment is crucial, certain nutritional supplements can complement conventional therapies and support nerve health. Let's explore several evidence-based supplements that may assist in reducing neuropathy symptoms and promoting overall nerve well-being. Please note that it is essential to consult with a healthcare professional before incorporating any supplements into your regimen.
Alpha-Lipoic Acid (ALA):
- ALA is a powerful antioxidant that helps protect nerve cells from oxidative stress.
- Studies have shown that ALA supplementation can alleviate neuropathic symptoms and improve nerve conduction velocity.
- Dosage: 600-1,200 mg per day. Split the dosage into two or three smaller doses for better absorption.

- Papanas N, et al. (2018). Efficacy of α-lipoic acid in diabetic neuropathy. Expert Opinion on Pharmacotherapy, 19(6), 597-605.
- ALC helps enhance nerve regeneration and supports mitochondrial function.
- Research suggests that ALC supplementation may alleviate pain and improve nerve function in individuals with neuropathy.
- Dosage: 1,000-2,000 mg per day, divided into two or three doses.

- B vitamins, especially B1 (thiamine), B6 (pyridoxine), and B12 (cobalamin), are crucial for nerve health and function.
- Deficiencies in these vitamins have been linked to neuropathy and supplementing with them may help alleviate symptoms.
- Thiamine: 300 mg per day.
- Pyridoxine: 100-200 mg per day.
- Cobalamin: 1,000-2,000 mcg per day.

- Studies suggest that supplementation with omega-3 fatty acids can alleviate neuropathic pain and improve nerve function.
- Dosage: 1-4 grams of combined EPA and DHA per day.

While nutritional supplements can play a complementary role in reducing neuropathy symptoms, it is crucial to approach them as part of a comprehensive treatment plan. These supplements, including alpha-lipoic acid, acetyl-L-carnitine, B vitamins, magnesium, and omega-3 fatty acids, have shown promise in supporting nerve health and reducing neuropathic symptoms. However, it is important to consult with a healthcare professional before starting any new supplement regimen to ensure safety and appropriate dosage for individual needs. By combining these supplements with appropriate medical care and/or alternative care therapies, individuals with neuropathy can take proactive steps toward improving their quality of life and overall nerve well-being.
