Finally, scar tissue forms to mimic the structure of the skin before the wound to heal the tissue. That said, there are many reasons why a wound is slow to heal. Certain wounds take longer to heal than others (i.e., leg or foot ulcers). Poor nutrition can also damage the body's ability to heal wounds. Too few calories, especially from proteins, and inadequate vitamin (and zinc) intake may affect wound healing. An infected wound harboring a large number of bacteria usually slows the healing process.
What is a leg ulcer? A leg ulcer is simply a break in the skin of the leg, which allows air and bacteria to get into the underlying tissue. This is usually caused by an injury, often a minor one that breaks the skin. In most people such an injury will heal up without difficulty within a week or two.
