According to the American Diabetes Association, about 15.7 million people (5.9 percent of the United States population) have diabetes. Nervous system damage (also called neuropathy) affects about 60 to 70 percent of people with diabetes and is a major complication that may cause diabetics to lose feeling in their feet or hands.

Foot problems are a big risk in diabetics. Diabetics must constantly monitor their feet or face severe consequences, including amputation.

With a diabetic foot, a wound as small as a blister from wearing a shoe that's too tight can cause a lot of damage. Diabetes decreases blood flow, so injuries are slow to heal. When your wound is not healing, it's at risk for infection. As a diabetic, your infections spread quickly. If you have diabetes, you should inspect your feet every day. Look for puncture wounds, bruises, pressure areas, redness, warmth, blisters, ulcers, scratches, cuts and nail problems. Get someone to help you, or use a mirror. 

People with diabetes are prone to having foot problems, often because of two complications of diabetes: nerve damage (neuropathy) and poor circulation. Neuropathy causes loss of feeling in your feet, taking away your ability to feel pain and discomfort, so you may not detect an injury or irritation. Poor circulation in your feet reduces your ability to heal, making it hard for even a tiny cut to resist infection.

Having diabetes increases the risk of developing a wide range of foot problems. Furthermore, with diabetes, small foot problems can turn into serious complications.

Diabetes-related Foot and Leg Problems

  • Infections and ulcers (sores) that don’t heal. An ulcer is a sore in the skin that may go all the way to the bone. Because of poor circulation and neuropathy in the feet, cuts or blisters can easily turn into ulcers that become infected and won’t heal. This is a common – and serious – complication of diabetes and can lead to a loss of your foot, your leg, or your life. 
  • Corns and calluses. When neuropathy is present, you can’t tell if your shoes are causing pressure and producing corns or calluses. Corns and calluses must be properly treated or they can develop into ulcers. 
  • Dry, cracked skin. Poor circulation and neuropathy can make your skin dry. This may seem harmless, but dry skin can result in cracks that may become sores and can lead to infection. 
  • Nail disorders. Ingrown toenails (which curve into the skin on the sides of the nail) and fungal infections can go unnoticed because of loss of feeling. If they are not properly treated, they can lead to infection. 
  • Hammertoes and bunions. Nerve damage affecting muscles can cause muscle weakness and loss of tone in the feet, resulting in hammertoes and bunions. If left untreated, these deformities can cause ulcers. 
  • Charcot foot. This is a complex foot deformity. It develops as a result of loss of sensation and an undetected broken bone that leads to destruction of the soft tissue of the foot. Because of neuropathy, the pain of the fracture goes unnoticed and the patient continues to walk on the broken bone, making it worse. This disabling complication is so severe that surgery, and occasionally amputation, may become necessary. 
  • Poor blood flow. In diabetes, the blood vessels below the knee often become narrow and restrict blood flow. This prevents wounds from healing and may cause tissue death.
