New York State Basic EMT-B Practice Exam: Prep & Practice Tests

Untreated severe hypoglycemia can lead to permanent brain damage due to the critical role glucose plays as the primary energy source for the brain. When blood sugar levels drop significantly, the brain is deprived of necessary glucose, which can harm neural cells. Prolonged hypoglycemic episodes can result in neuronal injury and may eventually cause lasting effects on cognitive functioning and overall neurological health. Recognizing the severity of hypoglycemia and the urgency of treating it is essential in preventing these potentially irreversible consequences.
