Researchers believe that diabetic neuropathy is likely caused by a combination of factors, including:

Risk Factors

The following factors are thought to increase the risk of diabetic neuropathy:

Symptoms

Symptoms of diabetic neuropathy may include:

  • Numbness in the extremities
  • Tingling in the extremities
  • Pain in the extremities
  • Wasting of the muscles of the feet or hands
  • Indigestion
  • Nausea or vomiting
  • Diarrhea or constipation
  • Dizziness or faintness
  • Urination problems
  • Impotence or vaginal dryness
  • Weakness in arms and or legs.
  • Weakness of facial muscles resulting in:
    • Drooping eyelid
    • Drooping mouth
    • Facial Droop
    • Difficulty swallowing.
  • Muscle Cramps

Diagnosis

Your doctor will ask about your symptoms and medical history, and perform a physical exam. Other tests may include:

  • Foot exam—to assess sensation in the foot
  • Nerve conduction studies —to test nerve activity
  • Electromyography —to determine how muscles respond to nerve signals
  • Quantitative sensory testing—the use of stimuli (eg, vibration) to check for neuropathy
  • Heart rate tests—to determine how the heart responds to changes
  • Ultrasound—to view internal organs
  • Biopsy —to remove a sample of nerve or skin tissue for examination

Treatment

Talk with your doctor about the best treatment plan for you. Treatment options include:

Blood Glucose Management

It is important to regularly monitor blood glucose levels and bring them within normal range with meal planning, exercise, and/or medications.

Foot Care

If you have diabetic neuropathy, you will need to take special care of your feet, since the nerves in the feet are the ones most often affected by neuropathy. This care will involve regular visits to a foot doctor and careful cleaning, inspection, moisturizing, and grooming of your feet. In addition, always wearing well-fitting shoes or slippers and thick, soft, seamless socks can help protect your feet from injuries.

Other Treatments

Other treatments will depend on your symptoms. Pain medications can be used to relieve pain, burning, tingling, or numbness. Modifying your diet and/or taking erythromycin or another antibiotic can help with gastrointestinal problems. Taking care when sitting or standing, increasing salt intake, or taking medications can help manage dizziness and weakness. An antibiotic can be prescribed to treat a urinary tract infection . Medications can be used to treat erectile dysfunction, and vaginal lubricants are recommended to treat vaginal dryness.

Prevention

The best way to prevent diabetic neuropathy is to regularly monitor and manage your blood glucose levels. Your doctor can instruct you about how often to check your levels, and what the numbers mean.
