Why do wounds heal slower in some people?

Wound healing depends on blood flow, immune response, and cell repair. Conditions like diabetes, poor circulation, or immune deficiencies can slow this process. Smoking, poor nutrition, and advanced age also reduce healing efficiency. Chronic inflammation or infection at the wound site delays tissue repair. Proper wound care, adequate hydration, and a protein-rich diet help recovery. Managing blood sugar and avoiding infection are critical for faster healing. Persistent wounds should be examined by a healthcare professional to rule out underlying vascular or metabolic disorders.
