Peripheral Neuropathy Signs & Symptoms

Peripheral neuropathy is nerve damage to the peripheral nervous system. The nervous system is divided into two categories. The central nervous system is the brain and spinal cord. All other nerves are part of the peripheral nervous system.

Types

• Symptoms of peripheral neuropathy depend on which type of nerve is affected. Types of peripheral nerves include sensory nerves (those that carry sensations), motor nerves (those that control movement) and autonomic nerves (those that control automatic functions). Neuropathy can affect any one type or all three types.

Sensory Nerve Damage

• Damage to sensory nerves causes loss of sensation. Symptoms include numbness, tingling, burning and nerve pain. Sensory nerve damage usually begins in the feet and gradually progresses to other areas of the body.

Motor Nerve Damage

• Motor nerve damage causes weakness and interferes with muscle control. You may experience difficulty moving part of your body, or you may experience twitching and cramping. You may find that you are falling often.

Autonomic Nerve Damage

• Autonomic nerve damage affects involuntary functions. Symptoms of autonomic nerve involvement include dizziness, constipation, diarrhea, impotence and incontinence. Other symptoms include difficulty eating or swallowing.

Prevention/Solution

• Carefully manage any medical condition that puts you at risk for peripheral neuropathy, particularly diabetes and alcoholism. Eat a healthy diet that includes plenty of fruits, vegetables and whole grains. Avoid cramped positions, repetitive movements and toxic chemicals, which can all cause nerve damage.
