Presence of which of the following conditions in urine are indicative of diabetes mellitus?

Answer: (A) Ketonuria and Glycosuria. Answer: (a) Ketonuria and Glycosuria Solution: Prolonged hyperglycemia in diabetes mellitus causes loss of glucose through urine (glycosuria) and formation of harmful ketone bodies that appear in urine (ketonuria).

  1. A.Ketonuria and Glycosuria✓
  2. B.Renal calculi and Hyperglycaemia
  3. C.Uremia and ketonuria
  4. D.Uremia and Renal Calculi

Correct Answer

(A) Ketonuria and Glycosuria

Solution & Explanation

Answer: (a) Ketonuria and Glycosuria Solution: Prolonged hyperglycemia in diabetes mellitus causes loss of glucose through urine (glycosuria) and formation of harmful ketone bodies that appear in urine (ketonuria). Hence ketonuria and glycosuria are the urinary indicators of diabetes mellitus, distinguishing it from the renal/uremia options. NCERT Reference: Chapter 19, Page 246, Line(s) 9-11 — "Prolonged hyperglycemia leads to a complex disorder called diabetes mellitus which is associated with loss of glucose through urine and formation of harmful compounds known as ketone bodies."
