High glucose in urine but not blood could indicate a condition called renal glycosuria. This occurs when the kidneys’ ability to reabsorb glucose is impaired, causing glucose to leak into the urine despite normal blood sugar levels. It is important to consult a healthcare professional for accurate diagnosis and appropriate management of this condition.

FAQs & Answers

  1. What causes glucose to appear in urine but not in blood? Glucose in urine but normal blood glucose levels can be caused by renal glycosuria, where the kidneys fail to reabsorb glucose effectively.
  2. Is renal glycosuria dangerous? Renal glycosuria is generally benign but should be evaluated by a healthcare provider to rule out other conditions.
  3. How is renal glycosuria diagnosed? Diagnosis involves urine and blood tests to measure glucose levels and assess kidney function.
