Does high blood sugar affect wound healing?

High blood sugar levels can affect wound healing. When blood glucose is elevated, the wound healing process is impaired for several main reasons: 1. Impaired protein synthesis: High blood sugar interferes with protein synthesis, leading to insufficient nutrient supply required for wound healing, thereby delaying the healing process. 2. Reduced white blood cell function: A high-glucose environment diminishes the ability of white blood cells to kill bacteria, compromising the wound's resistance to infection and impairing healing. 3. Favorable environment for bacterial growth: Glucose in the blood provides a favorable medium for bacterial proliferation, increasing the risk of wound infection and further disrupting healing. To address wound healing issues caused by high blood sugar, patients should first control their blood glucose levels, ensuring they remain within the normal range.
