According to the Canadian Diabetes Association, there are more than 9 million Canadians living with diabetes or pre-diabetes. There were 4,400 diabetes-related amputations in 2008.
Diabetes is a chronic, often incapacitating and sometimes deadly disease, in which the body either cannot produce insulin or cannot properly use the insulin it produces. This leads to high levels of glucose in the blood, which can damage organs, blood vessels, and nerves. Nervous system damage (also called neuropathy) affects about 60 to 70 percent of people with diabetes and is a major problem that may cause diabetics to lose feeling in their feet or hands.
With a diabetic foot, a wound as small as a blister caused from wearing a shoe that’s too constricted can cause a lot of damage. Diabetes decreases blood flow, so injuries are slow to heal. Also, diabetics often have reduced sensation, especially to their feet, so an injury may go undetected. 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.
Areas of high pressure are especially susceptible to develop corns and calluses that may become wounds and come infected. Diabetic and Advanced Foot care Nurses are highly skilled in reducing calluses and corns, in order to prevent wounds from occurring. It is also advisable for diabetics to wear proper footwear and custom foot orthotics, in order to reduce areas of high pressure.
