If you’ve ever experienced tingling, numbness, burning, or stabbing sensations in your hands or feet, you might be dealing with peripheral neuropathy—a condition that affects the nerves outside the brain and spinal cord. While these symptoms may start subtly, they can gradually worsen, impacting daily life and mobility. Understanding the root causes of peripheral neuropathy is essential to managing and potentially preventing it.
Peripheral neuropathy occurs when the peripheral nerves—those responsible for sending messages between your central nervous system and the rest of your body—become damaged or dysfunctional. This can affect sensory, motor, or autonomic nerves, leading to a variety of symptoms depending on the nerves involved.
The condition is not a single disease, but rather a symptom of a number of underlying problems. Let’s delve into the most common causes.
By far, the most common cause of peripheral neuropathy is diabetes, particularly when blood sugar levels are not well controlled. High glucose levels can damage nerves over time, especially in the legs and feet—a condition known as diabetic neuropathy.
Diabetes-related neuropathy affects up to 50% of people with the disease and is often the reason behind foot ulcers, infections, and, in severe cases, amputations. Early management of blood sugar levels is vital to preventing long-term nerve damage.
Excessive alcohol consumption over a long period can lead to alcoholic neuropathy. Alcohol is toxic to nerve tissue and can impair the absorption of essential nutrients like B vitamins, which are vital for nerve health. Individuals with alcoholic neuropathy may experience muscle weakness, cramps, and balance issues.
Deficiencies in certain vitamins, especially B1 (thiamine), B6, B12, and E, can significantly impair nerve function. Vitamin B12 deficiency, in particular, is known for causing nerve damage that can lead to numbness, tingling, and difficulty walking. Vegans, vegetarians, and individuals with absorption disorders are more at risk.
Several infections can cause peripheral nerve damage. These include:
Shingles (herpes zoster)
HIV/AIDS
Lyme disease
Hepatitis C
Additionally, autoimmune diseases like lupus, rheumatoid arthritis, and Guillain-Barré syndrome can lead to inflammation and subsequent nerve damage.
Certain medications can be neurotoxic. Chemotherapy drugs are a prime example; many cancer patients report tingling or numbness during or after treatment. Other drugs known to cause neuropathy include some antibiotics, anticonvulsants, and heart or blood pressure medications.
Environmental toxins such as arsenic, lead, and mercury can also damage peripheral nerves if a person is exposed to them over time.
Physical trauma is a more straightforward cause of peripheral neuropathy. Injuries that compress or sever nerves—such as car accidents, falls, or repetitive stress injuries (like carpal tunnel syndrome)—can result in localized or widespread nerve damage.
Surgical procedures can also inadvertently damage nerves, especially when operating near nerve clusters.
Certain inherited disorders, such as Charcot-Marie-Tooth disease, can cause peripheral neuropathy. While these genetic conditions are less common, they often lead to progressive muscle weakness and coordination problems that begin in adolescence or early adulthood.
When the kidneys or liver are not functioning properly, toxins can accumulate in the body. This buildup may lead to nerve damage over time. People with chronic kidney disease, especially those on dialysis, are at an increased risk of developing uremic neuropathy.
If you suspect you may have peripheral neuropathy, it’s important to consult a healthcare provider. Diagnosing the condition typically involves:
A detailed medical history
Physical and neurological exams
Blood tests
Imaging studies or nerve conduction tests
Identifying the underlying cause is the key to effective treatment. In some cases, addressing the root issue—like managing diabetes or correcting a vitamin deficiency—can slow or even reverse nerve damage.
While not all causes of peripheral neuropathy are preventable, many are. Here are some proactive steps:
Maintain healthy blood sugar levels.
Limit alcohol intake.
Eat a balanced diet rich in B vitamins.
Avoid exposure to toxins.
Manage chronic conditions with regular medical care.
Additionally, a combination of physical therapy, prescribed medications for nerve pain, and healthy lifestyle adjustments can significantly improve daily comfort and mobility. If you're experiencing ongoing symptoms, visiting a neuropathy clinic near you can provide targeted care and help you regain control of your nerve health.
Peripheral neuropathy is more than a tingling sensation—it’s often a sign that something deeper is going on within the body. By understanding its causes and taking steps toward prevention and treatment, individuals can protect their nerve health and lead more comfortable, active lives. If tingling, numbness, or unexplained pain is part of your daily experience, don’t ignore it. Early action makes a difference.
