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. This leads to saturation of receptors in the kidneys, and occurs at plasma glucose levels above 11 mmol/L^{[citation needed]}.

Renal glycosuria, also known as renal glucosuria, 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 (renal) 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 primary components of nephrons, the filtering units of the kidneys.

In most affected individuals, the condition causes no apparent symptoms (asymptomatic) 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^{[citation needed]}.
