Glucose is the source of energy in the body and is regulated by insulin and glucagon. Glucose passes freely through the renal glomeruli and is totally reabsorbed in the renal tubules. As plasma glucose levels rise this mechanism is saturated and the ‘renal threshold’ exceeded, glucose then appears in the urine. Renal thresholds for the dog and cat are approximately 10-12mmol/l. | Glucose is the source of energy in the body and is regulated by insulin and glucagon.
