Diabetes is basically carbohydrate intolerance and insulin resistance. There are two types; one of which is related to the inability of insulin secretion and in the other type the own defense system destroys the produced insulin. The diabetic foot occurs with hyperglycemia, when the blood glucose levels are very high. The pathology behind diabetic feet is that the high blood sugar content damages the nerve fibres of the peripheries basically of the feet. This term is then referred to as diabetic neuropathy. It will cause numbness, tingling, pain, or a loss of feeling in your feet.
Sometimes people lose sensation in their feet. This is when the most damage has occurred when the nerve fibers have been damaged. You might not know when you are getting ulcers and blisters, and even cuts on your feet.
