Glycosuria Causes and Endocrine Disorders

Polyuria and thirst are common symptoms associated with glycosuria.

Urine glucose measurements can be misleading due to the variation in renal threshold for glucose among diabetic patients.

Urine tests are painless and inexpensive compared to blood tests.
