What Causes Neuropathy? Common Reasons for Nerve Pain, Tingling, and Numbness

Main Causes of Neuropathy

Neuropathy happens when nerves become damaged. Nerves carry messages between your brain, spinal cord, and the rest of your body. When nerves stop working correctly, you notice symptoms like tingling, numbness, burning, weakness, or sharp, shooting pain in the hands or feet.

Diabetes

One of the most common causes of neuropathy is diabetes. Elevated blood sugar damages nerves and the small blood vessels that help nourish them. High triglycerides may also play a role. This is why diabetic neuropathy is especially common in the legs and feet of people with long-standing blood sugar problems. In fact, diabetes is considered the most common overall cause of neuropathy.

Vitamin Deficiencies

Another possible cause is vitamin deficiency, especially low levels of certain B vitamins. Nerves depend on good nutrition to stay healthy. When the body does not get the nutrients it needs, nerve function can suffer. Blood testing is often used during evaluation because low vitamin levels and other metabolic problems may contribute to neuropathy symptoms.

Injuries and Nerve Compression

Injuries and nerve compression can also lead to neuropathy. A fall, accident, repetitive movement, sports injury, herniated disc, or pinched nerve may stretch, crush, or irritate a nerve. In some people, this affects one area, while in others it may create pain, numbness, or weakness that travels down an arm or leg.

Other Neuropathy Triggers

Some cases are linked to infections, autoimmune conditions, toxins, alcohol use, medications, and inherited disorders. Mayo Clinic and NINDS both note that neuropathy may result from infections, exposure to toxins, metabolic problems, and inherited causes. Chemotherapy, chronic alcohol use, and certain medical conditions can also damage nerves. Some people may even have hereditary neuropathy, such as Charcot-Marie-Tooth disease.

Certain health conditions may raise the risk as well. Hypothyroidism can be associated with peripheral neuropathy, and autonomic neuropathy can also be caused by diabetes, infections, medications, and other diseases. Because there are many possible causes, a person should not assume all tingling or burning is “just poor circulation” or simply part of aging.
