Foot complications are common in diabetic patients and often are caused by the body's poor circulatory system. According to PodiatryChannel.com, leg and foot problems are the primary cause of hospitalization for diabetics. Diabetes is also the main reason for amputations below the knee. Foot complications related to diabetes show different symptoms. Understanding and identifying symptoms of infection in a diabetic's feet is essential to prevent complications. Left untreated, symptoms may lead to further infections, amputations and serious life-threatening situations.
Nerve Dysfunction
Excess sugar in the body may damage the body's nervous system. A diabetic may experience loss of sensation in the feet, shooting pain, tingling or a burning sensation. Feet may have a "pins and needles" sensation. The feeling is known as diabetic neuropathy and is caused by deterioration of nerve function in extremities.
Injury and Infection
Due to the loss of sensation in the feet, small cuts, bruises and injuries may lead to further infection. A diabetic may simply not feel an injury is present in the foot before an infection sets in. Due to poor circulation, a diabetic's foot does not heal quickly. Infection can set in promptly, causing further complications. The PodiatryChannel.com suggests a diabetic wash and inspect his feet daily for signs of injury or infection.
Skin Changes
The American Diabetes Association (ADA) reports a diabetic's feet may become dry, leading to cracks and skin peeling. The nerves that control oil production in the foot eventually become dysfunctional or stop working altogether. The ADA recommends applying a thin layer of petroleum jelly or light cream to the feet; however, never apply lotion between the toes, where moisture can turn into fungi or further infection. Calluses, or thick patches of skin, build up faster on diabetic feet. The ADA suggests using a pumice stone daily to wear down the thick areas of skin. Calluses, if left alone, break down and turn into ulcers. Ulcers often occur on the ball of the foot or bottom of the large toe. Untreated ulcers can lead to infections as well as possible amputation of the foot.
