Sugars A high level of glucose and other sugars in the urine (glycosuria) is often a symptom of diabetes mellitus. Glycosuria can also be caused by advanced kidney disease, Cushing's syndrome, impaired tubular reabsorption, shock, a rare tumor of the adrenal gland (pheochromocytoma), or cancer of the pancreas.lycosuria Glycosuria or glucosuria is a condition of osmotic diuresis typical in those suffering from diabetes mellitus. It leads to excretion of glucose in the urine. Due to a lack of the hormone insulin, plasma glucose levels are above normal.
Glycosuria or glucosuria is the excretion of glucose into the urine. Ordinarily, urine contains no glucose because the kidneys are able to reclaim all of the filtered glucose back into the bloodstream. Glycosuria is nearly always caused by elevated blood glucose levels, most commonly due to untreated diabetes mellitus.Rarely, glycosuria is due to an intrinsic problem with glucose reabsorption within the kidneys themselves, a condition termed renal glycosuria.lycosuria is nearly always caused by elevated blood glucose levels, most commonly due to untreated diabetes mellitus.
