Hypoglycemia is low blood glucose; hyperglycemia is high blood glucose. Which option correctly matches signs to each condition?

• A. Hypoglycemia is high blood glucose; hyperglycemia is low blood glucose; tremor and sweating are signs of hyperglycemia; polydipsia and polyuria are signs of hypoglycemia.
• B. Hypoglycemia is low blood glucose; hyperglycemia is high blood glucose; tremor and sweating are signs of hypoglycemia; polydipsia and polyuria are signs of hyperglycemia.
• C. Hypoglycemia is low blood glucose; hyperglycemia is high blood glucose; tremor and sweating are signs of hyperglycemia; polydipsia and polyuria are signs of hypoglycemia.
• D. Hypoglycemia is low blood glucose; hyperglycemia is high blood glucose; tremor and sweating are signs of hypoglycemia; polydipsia and polyuria are signs of hypoglycemia.

Answer: (B)

When blood glucose is low, the body mounts adrenergic signs like tremor and sweating as quick warning signals. When glucose is high, the body shows signs from osmotic diuresis such to polydipsia (increased thirst) and polyuria (increased urination). So the correct match is low blood glucose with tremor and sweating, and high blood glucose with polydipsia and polyuria.

Other options mix up these signs or assign the wrong glucose context, which would misrepresent how the body responds to hypo- and hyperglycemia.
