Glycosuria

Or glucosuria is an abnormal condition of osmotic diuresis due to excretion of glucose by the kidneys into the urine.

Appearance of glucose in the urine, as in diabetes and after the administration of drugs that lower the renal threshold.

Presence of sugar, particularly glucose, in the urine.

Sugar in the urine typical of diabetes mellitus.

A high level of sugar in the urine, a symptom of diabetes mellitus.

Presence of abnormally high levels of sugar, especially glucose, in the urine, due to ingestion of large amounts of carbohydrates, kidney disease, diabetes mellitus, or other metabolic disorder.

The excretion of abnormally large amounts of glucose in the urine; also known as renal glycosuria. In pathologic glycosuria, large amounts of glucose appear in the urine for considerable periods. Pathologic glycosuria usually results from diabetes mellitus and occurs when the pancreas fails to produce sufficient insulin or the body is resistant to the insulin it makes (type 2 diabetes). This causes an abnormally high blood sugar level, leading to frequent or continuous elimination of glucose in the urine. When the blood sugar level is normal, glycosuria may be caused by the failure of certain cells in the kidneys to reabsorb glucose as urine is produced. The defect in itself is not harmful.

The presence of glucose in the urine in abnormally large amounts. Only very minute quantities of this sugar may be found normally in the urine. Higher levels may be associated with diabetes mellitus, kidney disease, and some other conditions.

The presence of sugar in the urine. By far the most common cause of glycosuria is diabetes mellitus, but it may also occur as a result of a lowered renal threshold for sugar, when it is called renal glycosuria, and is not a sign of disease.

An abnormal amount of glucose in the urine. Traces of sugar, particularly glucose, may occur in normal urine but are not detected by ordinary qualitative methods. The presence of a reducing sugar found during routine urinalysis is suggestive but not diagnostic of diabetes mellitus. It is found when the blood glucose level exceeds the renal threshold (about 170 mg/dl of blood). The fasting level of blood glucose is normally between 70 and 99 mg/dl of blood.

Glycosuria is a condition characterized by the presence of glucose in the urine. It occurs when the kidneys fail to reabsorb glucose back into the bloodstream after the blood has been filtered to eliminate waste products.

The inability to adequately reabsorb glucose could be due to hyperglycemia (an unusually high blood glucose level), as seen in conditions like diabetes mellitus. It can also happen if the kidney tubules are damaged, such as through drug poisoning, making them unable to reabsorb even standard amounts of glucose. Furthermore, glycosuria may appear during pregnancy; however, it’s typically not serious as long as the blood glucose level remains normal and no other symptoms are present.

Glycosuria is identified through the examination of urine. The appropriate treatment varies depending on the underlying cause.
