Which of the following statements regarding hypoglycemia is FALSE?
A.Counter regulatory hormones are released in a hypoglycemic state
B.Hypoglycemia causes both autonomic and neuroglycopenic symptoms
C.Hypoglycemic patients commonly present with altered levels of consciousness, lethargy, confusion, or agitation
D.Hypoglycemia is diagnosed when the blood glucose is less than 60 mg/dL
E.Glucagon is ineffective in the treatment of alcohol-induced hypoglycemia
Answer & Comments
•D
•Comments:
–The serum glucose level that causes hypoglycemic symptoms is variable.
–Levels of 35 mg/dL and lower are present in asymptomatic individuals, and levels in the “normal” range can cause symptoms of hypoglycemia that resolve with glucose administration.
–Patients with hypoglycemia experience both neuro-glycopenic and autonomic symptoms.
–Neuroglycopenic symptoms result from a direct effect on the brain and manifest as dizziness, confusion, tiredness, difficulty speaking, and headache.
–Autonomic or sympathomimetic symptoms are due to release of the counter regulatory hormone epinephrine and include diaphoresis, anxiety, trembling, and nausea.
–Glucagon is ineffective in alcoholics and the elderly because they have low glycogen stores.
