About 60% to 70% of all people with diabetes will eventually develop peripheral neuropathy, although not all suffer pain. Yet this nerve damage is not inevitable. Studies have shown that people with diabetes can reduce their risk of developing nerve damage by keeping their blood sugar levels as close to normal as possible.
For most people, a bad shoe day means a blistered heel or painful arch that goes away quickly. But for people with diabetes, poor footwear can trigger serious problems, such as foot ulcers, infections, and even amputation.
Foot problems aren't inevitable, though. Ralph Guanci learned the hard way to pick his shoes with care and to stick with wearing them because they're good medicine for his feet.
Guanci, 57, a businessman in Carlisle, Massachusetts, was diagnosed with type 2 diabetes 25 years...
What causes peripheral neuropathy? Chronically high blood sugar levels damage nerves not only in your extremities but also in other parts of your body. These damaged nerves cannot effectively carry messages between the brain and other parts of the body.
This means you may not feel heat, cold, or pain in your feet, legs, or hands. If you get a cut or sore on your foot, you may not know it, which is why it's so important to inspect your feet daily. If a shoe doesn't fit properly, you could even develop a foot ulcer and not know it.
The consequences can be life-threatening. An infection that won't heal because of poor blood flow causes risk for developing ulcers and can lead to amputation, even death.
This nerve damage shows itself differently in each person. Some people feel tingling, then later feel pain. Other people lose the feeling in fingers and toes; they have numbness. These changes happen slowly over a period of years, so you might not even notice it.
Because the changes are subtle and happen as people get older, people tend to ignore the signs of nerve damage, thinking it's just part of getting older.
But there are treatments that can help slow the progression of this condition and limit the damage. Talk to your doctors about what your options are, and don't ignore the signs because with time, it can get worse.
Symptoms of Nerve Damage From Diabetes
Numbness is the most common, troubling symptom of nerve damage due to diabetes. The loss of sensation is a special concern. People who lose sensation are the ones most likely to get ulcers on their feet and to end up needing amputations.
