In a situation where we or a loved one has a difficult or long-term wound to heal, we need to realize that proper nutrition will support or directly enable the healing process. The body needs to supply both the basic building blocks for healing and other necessary components. Nowadays, great emphasis is placed on modern dressing materials, of which there is an abundance. They help eliminate infection or dead tissue, maintain a moist environment in the wound that is favorable for newly formed cells. Wound healing is a science today. Growth and inflammatory factors, enzymes, various complex mechanisms of wound formation (for example bedsores), possibilities for preventing them, and possibilities for their healing are investigated. Although there will be wounds that cannot heal, we are recording a significant number of successes. Any dressing material or procedure will work better when accompanied by good nutrition. Wound healing is not only a matter of local treatment, but always the overall care of the patient provided by experts in several fields. Nutritional support should be started early as this is a key area for good healing.
