Foot problems are common in people with diabetes. Any small cut or blister or ulcer is more prone to infection in Diabetic patients. How can diabetes affect the feet? Diabetes can cause two problems that can affect your feet: Diabetic Neuropathy: Uncontrolled diabetes can damage your nerves. If you have damaged nerves in your legs and feet, you might not feel heat, cold, or pain there. This lack of feeling is called "sensory diabetic neuropathy." If you do not feel a cut or sore on your foot because of neuropathy, the cut could get worse and become infected. Peripheral Vascular Disease: Diabetes also affects the flow of blood. Without good blood flow or reducing blood flow to feet, hampers the healing of foot ulcers. Poor blood flow in the arms and legs is called "peripheral vascular disease."
