What is the rationale behind the delayed healing of wounds in individuals afflicted with diabetes mellitus?
Response: There exist two paramount rationales for the protracted convalescence of wounds in diabetes mellitus:
PRIMARY: Elevated levels of blood glucose:
Elevated blood glucose levels can inflict damage upon the blood vessels and nerves throughout the body. This may engender compromised circulation to the extremities, notably the feet and digits. Impaired blood circulation entails that wounds will not receive the oxygen and nutrients requisite for optimal healing.
Additionally, heightened blood glucose levels can also debilitate the immune system, thereby rendering the body less adept at combatting infections.
SECONDARY: Weakened immune system:
Diabetes mellitus can enfeeble the body's immune system, thus rendering it more arduous to fend off bacteria that precipitate infections in wounds.
Immune system frailty arises from various factors, including the potential impact of elevated blood glucose levels on the performance of white blood cells.
CONSEQUENTLY: In the presence of diabetes mellitus, it is imperative to exercise heightened vigilance in scrutinizing the condition of one's feet. Inspect for abrasions or ulcers.
Even a minor injury can escalate into a formidable predicament.
