Edema can significantly affect wound healing by impeding blood flow and oxygen delivery to the tissues, which delays the healing process. When edema occurs, excess fluid accumulates in the tissues, which can increase interstitial pressure. This pressure can constrict blood vessels, reducing their ability to supply the necessary nutrients and oxygen that are critical for healing. Without adequate blood flow, the body's inflammatory response and repair mechanisms are compromised, leading to a longer and potentially complicated healing process. Furthermore, the presence of edema may increase the risk of infection, as the fluid pocket can serve as a breeding ground for pathogens, further complicating the healing trajectory.
