Why does chronic alcohol consumption increase the risk of hypoglycemia even when glycogen stores are present?

A)Increased insulin receptor sensitivity occurs
B)Ketogenesis inhibits liver gluconeogenesis
C)Ethanol metabolism inhibits gluconeogenesis
D)Glycogenolysis becomes severely impaired

💡 Explanation

Chronic alcohol consumption increases the risk of hypoglycemia because ethanol metabolism in the liver increases the NADH/NAD+ ratio, inhibiting gluconeogenesis, a process critical for glucose production. Therefore, the liver can't synthesize glucose, rather than increased receptor sensitivity compensating or glycogenolysis being severely impaired.
