KROK 1 2015 – Question 83 · KROK (Medicine) · Pathophysiology
According to the results of glucose tolerance test a patient has no disorder of carbohydrate tolerance. Despite that glucose is detected in the patients’s urine (5 mmol/l). The patient has been diagnosed with renal diabetes. What renal changes cause glucosuria in this case?
- A. Increased activity of glucose reabsorption enzymes
- B. Increased glucose filtration
- C. Increased glucose secretion
- D. Decreased activity of glucose reabsorption enzymes
- E. Exceeded glucose reabsorption threshold
Hint
Because glucose tolerance is normal, think about what must differ in the kidney itself, comparing glomerular filtration with the tubular processing of glucose.
