Sugar in urine

What does sugar in urine mean?

When the sugar (glucose) detected in urine, that means you have a high level of bloody sugar, so that the excess sugar will be discharged from blood into urine.

Sugar in urine causes

Any cause leading to high blood sugar or diabetes, will causes sugar in urine.

In normal, there is no sugar in urine. When the blood glucose level rises above renal glucose threshold (the maximum of blood glucose concentration, which does not cause sugar in urine), sugar will be present in the urine, called "glycosuria". The sugar in urine is an important clue, that suggests you may have diabetes mellitus. In spite of that, there will still be a deviation for diagnosis of diabetes. For example, with diabetes-induced renal glomerular sclerosis, there may be no sugar in urine; Another example, pregnancy-induced decrease of renal glucose threshold shows sugar in urine in healthy women, who have no diabetes, no hyperglycemia (high blood sugar).

The blood sugar test is more reliable for diagnosis of diabetes. That is to say, urine sugar test can be as a diagnostic clue and blood sugar test is a main basis for diabetes diagnosis.

If the pancreatic function and/or tissues and cells are impaired, it will lead to insulin deficiency thus to sugar in urine.
