The delayed healing of a diabetic foot ulcer is mainly due to poor blood circulation and weakened immune response. In diabetes, high glucose levels damage blood vessels, making it harder for the body to deliver essential nutrients to the wound. This directly affects the wound healing in diabetes process. Additionally, reduced sensation in the feet may cause minor injuries to go unnoticed, increasing the risk of infection. Effective diabetic wound care involves keeping the wound clean, protected, and free from pressure. Proper foot ulcer treatment also includes controlling blood sugar levels and maintaining hygiene. With the right care and monitoring, healing can be improved and complications can be minimized.
