[As published in SouthwestHealth] Happy feet are an important part of a healthy body, yet most of us don't give our feet much thought. But for someone with diabetes, having healthy feet can be a real challenge.
Higher than normal blood sugar levels can, over time, damage blood vessels and nerves. When nerves are damaged, you may develop diabetic neuropathy. With this condition, you might feel burning pain or you may lose feeling in parts of your body. When blood vessels in your feet are damaged, the tissues are not getting enough blood.
The loss of feeling makes it hard for you to tell if your foot is sore or if there are blisters. If you don't care for the blisters properly, they may become ulcers, which then could become infected. The reduced circulation makes it difficult for blisters or ulcers to heal, even with antibiotics.
Southwest's Wound Healing Center can help treat deep wounds or ulcers that may not heal on their own. Hyperbaric oxygen therapy can be a treatment option for severe wounds, such as diabetic foot wounds. But the best treatment is prevention.
- Manage your diabetes to keep your blood sugar level as close to normal as you can.
- Follow the diet, exercise and medication regimen your doctor recommends.
- Check your feet daily. You might have to use a mirror to see the bottoms of your feet or have a family member or friend help you.
- Wash your feet every day with lukewarm water and mild soap. Don't use hot water.
- Dry your feet thoroughly. Use a soft towel and pat gently, don't rub. And be sure to dry between your toes.
- If you see redness, swelling, blisters, sores or cracked skin, call your doctor.
- Call your doctor if you experience numbness or tingling in any part of your foot.
More tips for happy feet
Basic care:
- Use creams or lotions on your feet. Pay special attention to the heels.
- Dust with nonmedicated powder before putting on socks, stockings, or shoes to help keep your feet dry.
- Cut toenails straight across to prevent ingrown toenails.
- Check with your doctor before treating calluses, corns, or bunions.
- Keep your feet at a comfortable temperature. They shouldn't be too hot or too cold.

The right shoes and socks make a big difference
|
— Socks —
- Wear clean, dry socks.
- Change your socks every day.
- Avoid socks with tight elastic bands that can hinder circulation.
- Don't wear thick or bulk socks. They may fit badly and irritate the skin.
- Wear socks to bed if your feet get cold at night. Don't use heating pads or a hot water bottle — these might cause burns you may not feel.
- Always wear socks with shoes

— Shoes —
- Wear shoes that are the right size.
- Have your feet measured when you buy new shoes.
- Make sure your shoes are comfortable, not tight or too loose.
- Shop for shoes at the end of the day when your feet are a little swollen.
- Break in new shoes slowly. Wear them for an hour a day for several days.
- Avoid sandals or other open-toed shoes or shoes with high heels or pointed toes.
- Check your shoes before you put them on. Look for gravel, pebbles, torn linings, anything that might rub against your foot and cause blisters.
