Peripheral Neuropathy

Also known as: Nerve Damage, Polyneuropathy, Diabetic Neuropathy

Peripheral neuropathy refers to damage or dysfunction of the peripheral nerves, causing weakness, numbness, and pain, typically in the hands and feet. It affects an estimated 20 million people in the United States and has more than 100 known causes, with diabetes being the most common. Treatment focuses on managing the underlying condition and relieving symptoms.

Symptoms

Numbness or reduced sensation in the hands and feet
Tingling or prickling (pins and needles) sensations
Sharp, stabbing, or burning pain
Sensitivity to touch (allodynia)
Muscle weakness
Loss of coordination and balance
Difficulty with fine motor skills
Autonomic symptoms (blood pressure changes, digestive issues, sweating abnormalities)

Causes

  • Diabetes mellitus (most common cause)
  • Vitamin deficiencies (B1, B6, B12, folate)
  • Alcoholism and chronic liver disease
  • Autoimmune diseases (Guillain-Barré syndrome, lupus, rheumatoid arthritis)
  • Chemotherapy and other neurotoxic medications
  • Infections (HIV, hepatitis C, Lyme disease, shingles)

Risk Factors

  • Poorly controlled diabetes
  • Heavy alcohol consumption
  • Vitamin B12 deficiency
  • Exposure to industrial toxins or heavy metals
  • Family history of neuropathy
  • Kidney disease

Diagnosis

  • Neurological examination testing sensation, reflexes, and strength
  • Nerve conduction studies and electromyography (EMG)
  • Blood tests (glucose, HbA1c, vitamin levels, thyroid function, autoimmune markers)
  • Nerve biopsy or skin biopsy for small fiber neuropathy
  • MRI if nerve compression is suspected

Treatment

  • Treating the underlying cause (blood sugar control, vitamin supplementation, stopping toxic medications)
  • Neuropathic pain medications (gabapentin, pregabalin, duloxetine, amitriptyline)
  • Topical treatments (capsaicin cream, lidocaine patches)
  • Physical therapy to maintain strength and balance
  • Transcutaneous electrical nerve stimulation (TENS)

Prevention

  • Maintain tight blood sugar control if diabetic
  • Limit alcohol consumption
  • Eat a balanced diet with adequate B vitamins
  • Protect against repetitive stress injuries
  • Avoid exposure to neurotoxic substances

When to See a Doctor

  • Persistent numbness, tingling, or pain in the hands or feet
  • Muscle weakness interfering with daily activities
  • Loss of balance or frequent falls
  • Wounds on the feet that are slow to heal (especially with diabetes)
