At normal blood glucose levels, up to 97% of glucose filtered by the glomeruli is reabsorbed by sodium-dependent glucose transporter-2 (SGLT2) in the initial segment of the tubule, and only 3% of the remaining glucose is reabsorbed by sodium-dependent glucose transporter-1 (SGLT1) in the later segment of the proximal tubule (17)
