Final answer:
Hyperglycemia develops in patients with severe injury due to increased glucose concentration, impaired insulin function, and metabolic imbalances.
Step-by-step explanation:
Hyperglycemia develops in patients with severe injury due to several factors.
- Increased glucose concentration in the blood for a longer duration of time can lead to infections and delayed wound healing.
- In cases of renal dysfunction, hypoglycemia may be seen due to non-reabsorption of glucose by the kidney tubules.
- Impaired insulin function can also lead to hyperglycemia and diabetes mellitus, which can cause damage to blood vessels, nerves, kidneys, and other organs.
Uncontrolled diabetes can also lead to a dangerous form of metabolic acidosis called ketoacidosis.
