What are the causes of diabetic foot ulcers? Pathophysiology • neuropathy‐ leads to skin dryness and cracks, foot deformity and loss of protective sense in the foot • microangiopathy/vascular disease‐ lead to poor blood supply to the toes and foot and then ulcerate easily • immunopathy‐ defects in leukocyte function (leukocyte phagocytosis, neutrophil dysfunction) and also deficient w hite cell chemotaxis and adherence 11,12 hyperglycemia produces oxidative stress on nerve cells and leads to neuropathy. 11 additional nerve dysfunction follows from glycosylation of nerve cell proteins, leading to further ischemia.
Pathways to ulceration are displayed schematically in figure 1. A diabetic foot ulcer can be redness over a bony area or an open sore. The fluid may also contain pus or blood.
