Peripheral neuropathy is damage to the peripheral nerves, causing weakness, numbness, and pain, usually in the hands and feet. It can result from diabetes, infections, toxins, or other conditions.
Peripheral neuropathy affects an estimated 2–8% of the general population, with prevalence increasing significantly with age and in people with diabetes (up to 50% of diabetic patients develop neuropathy).
The peripheral nervous system carries signals between the brain, spinal cord, and the rest of the body. When these nerves are damaged, signalling is disrupted — leading to numbness, pain, weakness, or dysfunction in the affected areas.
There are over 100 types of peripheral neuropathy with various causes. Treatment focuses on addressing the underlying cause, managing symptoms, and preventing further nerve damage.
People with Peripheral Neuropathy often experience the following symptoms.
Numbness, tingling, burning pain, and loss of sensation, typically starting in the feet and hands (stocking-glove distribution).
Muscle weakness, cramping, and twitching. May lead to difficulty with fine motor tasks, foot drop, or problems with balance.
Dysfunction of involuntary body functions including blood pressure regulation, digestion, bladder control, and sweating.
Distinctive burning, shooting, or electric-shock-like pain that may be constant or intermittent and often worsens at night.
Certain factors may increase your likelihood of developing Peripheral Neuropathy.
Common approaches to managing peripheral neuropathy. Always consult a healthcare provider for personalized treatment.
Tight blood sugar control in diabetes, vitamin supplementation for deficiencies, or treating the underlying autoimmune condition.
Medications including gabapentin, pregabalin, duloxetine, and tricyclic antidepressants are first-line treatments for neuropathic pain.
Exercises to improve strength, balance, and coordination, along with assistive devices if needed for mobility.
Capsaicin cream or lidocaine patches can provide localised pain relief for affected areas.
Diagnosis involves neurological examination, nerve conduction studies, electromyography (EMG), blood tests (glucose, B12, thyroid), and sometimes nerve biopsy. The pattern of nerve involvement helps determine the underlying cause.
See a doctor if you experience persistent numbness, tingling, weakness, or pain in your extremities, especially if it is worsening or affecting your balance and daily activities.
Steps that may help reduce the risk of developing or worsening peripheral neuropathy.
Maintain good blood sugar control if diabetic
Limit alcohol consumption
Ensure adequate vitamin B12 intake
Protect extremities from injury
If left untreated or poorly managed, peripheral neuropathy may lead to:
It depends on the cause. Neuropathy from vitamin deficiency or medication toxicity may improve once the cause is addressed. Diabetic neuropathy can be slowed but is usually not fully reversible.
No. While diabetes is the most common cause, neuropathy can result from many conditions including autoimmune diseases, infections, alcohol use, vitamin deficiencies, and certain medications.
The most common pattern (length-dependent neuropathy) starts in the feet and progresses upward. However, some types can affect other areas first, depending on the underlying cause.
