Glucose reabsorption is mediated by the sodium-glucose cotransporter (SGLT) 2, which reabsorbs 90% of glucose, and SGLT1, which reabsorbs the remaining 10%.
The relationship between hyperglycaemia and the development of renal disease is complex. Hyperglycaemia-induced complications are mediated by several metabolic pathways, among which accumulation of Advanced Glycation End-products with abnormalities of the glycosylation of macromolecules and increased glucose flux through the polyol pathway seem to be the most important.
