Low threshhold: Ordinarily the kidney does not spill sugar into the urine until the blood level reaches about 180. However, if this kidney threshhold happens to be set at a much lower level, the sugar will begin to spill at a much lower level. This goes by the scientific name of renal glycosuria and has no relation to diabetes. ...Read more

Usually diabetes.: One of the functions of the kidney is to absorb all sugars into the bloodstream & prevent their excretion in the urine. Diabetes, or conditions where blood sugar is very high, can overwhelm the kidney's ability to reabsorb glucose, causing it to spill out into the urine, a condition called glycosuria. Though diabetes is the most common cause, rare defects in kidney function can cause this as well. ...Read more
