Diabetes can have many damaging effects on the legs and feet due to changes in the blood vessels and nerves. You may not feel a cut, blister, or sore if you've lost the feeling in your foot due to nerve damage. These injuries can lead to ulcers or infection. A diabetic ulcer is a breakdown of the skin on an area of the foot. It may be difficult to heal because damage to blood vessels prevents it from getting enough blood and oxygen. Without treatment, it may progress through layers of tissue. Ultimately the tissue may die, and amputation may be necessary. People with diabetes are also more likely to develop cellulitis, a bacterial type of infection. Cellulitis can affect both the skin and the fat underneath. It usually begins with a tear or break on the skin that permits bacteria to enter, but a weakened immune system sometimes allows it to start when skin has not been broken.
