Peripheral neuropathy can stem from various underlying conditions, each affecting the nerves differently. The primary causes include:

• Diabetes: High blood sugar levels can damage nerves over time, leading to diabetic neuropathy. This is one of the most common causes of peripheral neuropathy.

• Infections: Certain viral and bacterial infections, such as Lyme disease, shingles, or hepatitis C, can result in nerve damage.

• Injuries: Physical trauma to nerves, resulting from accidents or surgeries, can cause neuropathy. Repetitive stress injuries from activities like typing can also contribute.

• Autoimmune Disorders: Conditions like rheumatoid arthritis, lupus, and Guillain-Barré syndrome can attack nerve tissues, leading to neuropathy.

• Toxic Exposure: Prolonged exposure to toxins, such as heavy metals or chemotherapy drugs, can damage nerves.

• Vitamin Deficiencies: Deficiencies in vitamins like B1, B6, B12, and E can impair nerve health.

Early diagnosis and management of these underlying conditions are crucial. Regular check-ups and maintaining a healthy lifestyle can help in early detection and management of peripheral neuropathy. Recognizing the symptoms, such as tingling, numbness, and pain in the extremities, is vital for seeking timely medical intervention.
