In the context of wound healing, which factor can delay healing?

Uncontrolled diabetes is a significant factor that can delay wound healing due to its impact on various physiological processes. In individuals with poorly managed blood glucose levels, high levels of glucose can impair the function of immune cells, leading to a decreased ability to fight infections, which is crucial for the healing process. Additionally, elevated blood sugar can damage blood vessels and nerve tissues, reducing circulation and sensation in the affected area, which can further compromise healing. Furthermore, diabetes-related complications, such as neuropathy and peripheral vascular disease, can also contribute to delayed wound healing.

In contrast, increased protein intake supports wound healing by providing the necessary building blocks for tissue repair, regular exercise promotes circulation and overall health, and smoking cessation significantly improves oxygenation and circulation, both of which are beneficial for wound healing.
