Why is glucose control important in TBI patients?

• A. Both hyperglycemia and hypoglycemia worsen brain injury; maintain euglycemia with careful glucose management and nutrition
• B. Hyperglycemia is beneficial
• C. Glucose control has no impact
• D. Only hypoglycemia matters

Answer: (A)

Maintaining a steady, normal level of blood glucose is important because the brain relies on glucose for energy, and after a traumatic brain injury the brain is particularly vulnerable to energy failure. When glucose is too high (hyperglycemia), it can worsen brain injury by promoting edema, increasing oxidative stress and inflammation, and accelerating secondary damage. When glucose is too low (hypoglycemia), the brain can’t get enough energy, leading to neuronal injury and further damage. So the goal is to keep glucose in a normal range through careful glucose management and proper nutrition, avoiding both extremes. This approach explains why the option that highlights protecting the brain by preventing both hyperglycemia and hypoglycemia is the best. The other choices aren’t accurate because they either claim hyperglycemia is beneficial, say glucose control doesn’t matter, or focus only on hypoglycemia, ignoring the harm that hyperglycemia can cause.
