What is renal glycosuria?

Renal glycosuria is a rare condition in which the simple sugar glucose is excreted in the urine despite normal or low blood glucose levels. With normal kidney function, glucose is excreted in the urine only when there are abnormally elevated levels of glucose in the blood. However, in those with renal glycosuria, glucose is abnormally eliminated in the urine due to improper functioning of the renal tubules, which are the primary components of the filtering units of the kidneys. In most affected individuals, the condition causes no apparent symptoms or serious effects. When renal glycosuria occurs as an isolated finding with otherwise normal kidney function, the condition is thought to be inherited as an autosomal recessive trait.[1]

How might renal glycosuria be treated?

In most affected individuals, no treatment is required. However, some individuals with renal glycosuria may develop diabetes mellitus. Therefore, appropriate testing should be conducted to rule out diabetes and to regularly monitor those with confirmed renal glycosuria.[1]
