Study Notes

Glycosuria

  • Glycosuria is the presence of detectable glucose in urine.
  • This happens when blood glucose levels exceed the kidney's ability to reabsorb glucose.
  • Glucose can appear in urine without always having high blood sugar.
  • Factors like glomerular blood flow, tubular reabsorption, and urine flow influence glycosuria.
  • Glycosuria is usually seen when blood glucose is above 180-200 mg/dL if hyperglycemia is present.
