What Are the Causes of Peripheral Neuropathy?
A variety of factors and underlying Health conditions can lead to the development of Peripheral Neuropathy. While some rare cases are genetic and present from birth, the majority are acquired over time due to external or medical influences. Peripheral neuropathy occurs when the peripheral nerves - responsible for transmitting signals between the brain, spinal cord, and body - become damaged or malfunction. This can result in symptoms such as tingling, numbness, burning sensations, and muscle weakness, typically starting in the hands and feet and sometimes spreading to other areas.
Acquired peripheral Neuropathy is often idiopathic, meaning no clear cause can be identified, though in many cases doctors can trace it to specific contributing factors. Among the most common causes are generalized diseases such as diabetes, which leads to nerve damage due to prolonged high blood sugar levels. Physical trauma from accidents, falls, or repetitive motion can also harm nerves, while remaining immobile for extended periods can restrict blood flow and contribute to nerve compression.
Additionally, excessive alcohol consumption and exposure to environmental toxins can damage nerve tissue over time. Certain infections and autoimmune disorders can trigger the body’s immune system to mistakenly attack nerve cells, leading to inflammation and degeneration. In some cases, nutritional deficiencies - especially in B vitamins - can further exacerbate nerve damage and delay recovery.
