Glycosuria is a condition in which a person's urine contains more sugar, or glucose, than it should. It typically occurs due to high blood sugar levels or kidney damage. Glycosuria is a common symptom of both type 1 diabetes and type 2 diabetes.

What can the presence of glycosuria indicate?

Glycosuria. Glycosuria may indicate the presence of diabetes, but it is not diagnostic, nor does the absence of glycosuria exclude diabetes. In individuals with a low renal threshold, glucose may be present in the urine in the absence of hyperglycemia.

What is the most common cause of glycosuria?

Type 2 diabetes is the most common cause of glycosuria. If you have this condition, your body's insulin doesn't work properly in one of two ways. In some cases, insulin can't transport blood sugar into your body's cells effectively. This can cause blood sugar to be passed out in your urine instead.
