How does hyperglycemia affect wound healing?

• A. It enhances collagen synthesis
• B. It impairs immune response
• C. It speeds up healing
• D. It has no effect

Answer: (B)

Hyperglycemia, which refers to elevated levels of glucose in the blood, significantly impairs wound healing primarily due to its negative effects on the immune response. When blood glucose levels are high, various physiological processes become disrupted. For example, hyperglycemia can lead to alterations in white blood cell function, reducing their ability to migrate to sites of infection and to effectively engulf pathogens. This compromised immune response increases the risk of infections, which are major barriers to successful wound healing. Furthermore, hyperglycemia can also affect angiogenesis, the process by which new blood vessels form, and can impair fibroblast function, which is crucial for collagen production and tissue repair. These factors contribute collectively to a delayed healing process. Understanding how high blood sugar levels impact healing is vital for managing patients with diabetes or other conditions associated with hyperglycemia, as effective wound care strategies must consider these underlying issues for optimal recovery.
