- Normal Levels of Glucose in Urine
- Healthy individuals typically have no detectable glucose in urine, or levels are so low they are undetectable by routine testing.
- Elevated Glucose in Urine (Glucosuria)
- Diabetes Mellitus: High blood sugar levels overwhelm the kidneys' ability to reabsorb glucose, resulting in glucose spillage into the urine.
- Stress or Hormonal Changes: Temporary glucosuria can occur during physical stress, illness, or hormonal surges (e.g., in pregnancy or with corticosteroid use).
- Kidney Disorders (Renal Glucosuria): In rare cases, glucose appears in urine despite normal blood sugar levels due to a defect in kidney tubules, impairing glucose reabsorption.
- Transient Causes of Glucosuria
- High carbohydrate intake shortly before testing.
- Stressful situations, infections, or surgeries.
- Pregnancy-related changes in glucose metabolism.
