Hypoglycaemia unawareness is defined as which of the following?

• A. The inability to sense early hypoglycaemic symptoms.
• B. Increased thirst and urination at night.
• C. The inability to sense early hypoglycaemic symptoms, leading to increased risk of severe episodes.
• D. Hyperglycemia with no symptoms.

Answer: (C)

Hypoglycemia unawareness means you no longer recognize the early warning signs of low blood glucose. Normally the body signals danger with symptoms like tremor, sweating, and palpitations to prompt you to treat the low. When those warning signs fade, you may not realize you’re hypoglycemic until the level becomes quite low, which raises the risk of severe, potentially dangerous episodes. This definition aligns with describing an inability to sense early hypoglycaemic symptoms and noting that this loss of awareness leads to a higher risk of severe events. The other options point to unrelated or indirect issues—nocturnal thirst and urination suggest high blood glucose, not impaired awareness of hypoglycemia, and hyperglycemia without symptoms is simply high sugar with no warning signs, not specifically hypoglycemia unawareness.
