What stop wounds from healing?

Wounds not healing can be a result of factors relating to the patient themselves or the wound or other exogenous environmental factors. Patient factors which can impair wound healing include patient medical problems like diabetes, kidney disease, or if the patient has a wound on an arm or a leg, if the blood supply to that wound is poor or the circulation within the patient is poor, then the nutrients and oxygen delivery to that wound may not be sufficient to allow the wound to heal. Other factors, apart from patient factors, wound factors, if the wound is particularly large, deep, if the wound is not clean, if the wound becomes infected, if the wound is under tension. Exogenous factors such as the environment which the patient's in, if the wound isn't dressed regularly, isn't cleaned regularly, these environmental factors may be a recipe for the wound not healing. you
