What is Peripheral Neuropathy?

Peripheral neuropathy is referred to when damage of the peripheral nerves occurs. Your peripheral nervesthe nerves in your toes and fingertipsare the ones on the periphery of your body. When the nerves are damaged, they don’t function properly. People with peripheral neuropathy have decreased or abnormal sensation in their toes and fingers. Sometimes, they develop problems moving these parts of the body as well.

Causes of Peripheral Neuropathy

Diabetes is the most common cause of peripheral neuropathy. According to the American Diabetes Association, 60 to 70 percent of people with diabetes will develop neuropathy within their lifetime.

Other causes of peripheral neuropathy include:

  • Certain medications, including some chemotherapy drugs.
  • Some people have a family history of peripheral neuropathy.
  • Advanced age. Peripheral neuropathy is more common as people age.
  • Arthritis. Certain type of arthritis can cause peripheral neuropathy.
  • According to the US National Library of Medicine.
  • Neurological disorders.Certain neurological disorders, including spina bifida and fibromyalgia, are associated with peripheral neuropathy.
  • Acute injury to the peripheral nerves may also cause peripheral neuropathy.


Symptoms of Peripheral Neuropathy

Common symptoms of peripheral neuropathy include burning, numbness, tingling, or shooting or stabbing pain in the toes and/or fingertips. Change in sensation in the fingers or toes may be a symptom of peripheral neuropathy. Report any abnormal sensations in your toes and fingers to your doctor. Those sensations can be an early sign of other problems, such as diabetes.

 Home Care and treatment

You should always inspect your feet regularly if you have peripheral neuropathy. Decreased sensation may develop eventually, you might not notice an injury or infection. Someone who has diabetes and peripheral neuropathy with loss of protective sensation, for instance, could step on a tack without noticing it. Regularly inspect your feet so you can note any injuries or infections and seek appropriate medical attention as needed.

If you’re unable to properly inspect your own feet, enlist a family member or friend to help you. It’s absolutely essential that any injuries are caught and treated promptly. Otherwise, an infection can develop and progress.

People with peripheral neuropathy should wear properly fitted shoes and avoid walking barefoot to prevent injury. If you have diabetes, it’s important to control your blood sugar as well, because out-of-control blood sugar leads to increased nerve damage. Take your insulin or medication as prescribed and follow the recommended diet.

 When to Visit a Podiatrist

If you have Peripheral Neuropathy or suspect it, you should consult with a Podiatrist early on. It’s important to have an ongoing treatment plan.

 Diagnosis and Treatment

Many types of medical professionals including a podiatrist, family physician, internist, or physician who specializes in diabetes can diagnose peripheral neuropathy. The diagnosis is made on the basis of a physical exam, health history, and your reporting of symptoms. The doctor may order a blood test to check your blood sugar level because high blood sugar levels and diabetes are an important cause of peripheral neuropathy.

There is no known cure for peripheral neuropathy. The goal of treatments are to slow the progression of the disease, to maintain foot health, and to decrease pain (if present) and improve the quality of life.

The podiatrist often prescribes oral medication to help with pain a thorough foot check to look for any injuries or infections and will teach you how to do the same. Your podiatrist will also show you how to take care of your feet at home. People who have peripheral neuropathy should have their feet examined by a podiatrist at least once per year.

If you also have diabetes, the podiatrist will work closely with you and other health-care professionals. Controlling the patient’s blood sugar levels with diet, exercise, and medication (if needed) can slow the progression of peripheral neuropathy and maintain foot health.

 Prevention of Peripheral Neuropathy

Keeping your blood sugar levels under control is the the best thing you can do to prevent peripheral neuropathy. Peripheral neuropathy is common in people with diabetes, but the degree of neuropathy generally corresponds to the degree of blood sugar control. Someone whose blood sugar is kept under tight control will usually have much better sensation in their fingers and toes than someone with poorly controlled diabetes.
