Diabetes is a condition in which a person has high blood sugar (glucose) because the body either does not produce enough insulin, the body’s cells do not respond properly to insulin — or both. Referred to by doctors as diabetes mellitus, symptoms often include frequent urination, unusually high levels of thirst and hunger, numbness and tingling in the feet, cold feet, and sores or ulcers that don’t heal.
Because of decreased circulation, people with diabetes often do not feel sores, infection and other ailments on their feet. They are also vulnerable to complications associated with foot disorders like corns, calluses and bunions. Therefore doctors and many medical sites like WebMD, MedlinePlus and Medscape advised that diabetic patients should check and wash their feet every day, keep the toenails properly trimmed, and visit a health care provider for any foot related problems rather than try to treat these ailments at home. Failure to catch foot infections and other problems in the extremities in a timely manner could lead to gangrene and, in some cases, limb amputation.
