Renal glucose reabsorption

From Wikipedia, the free encyclopedia

Renal glucose reabsorption is the part of renal physiology that deals with the retrieval of filtered glucose, preventing it from disappearing from the body through the urine.

If glucose is not reabsorbed by the kidney, it appears in the urine, in a condition known as glucosuria. This is associated with diabetes mellitus.^[1].

Characteristics of Glucose reabsorption

Characteristic	proximal tubule			loop of Henle	Distal convoluted tubule	Collecting duct system
	S1	S2	S3
reabsorption (%)	98[2]			Beyond the proximal tubule: 2%[2]
reabsorption (mmoles/day)
Concentration
apical transport proteins	SGLT2[2]		SGLT1[2]
basolateral transport proteins	GLUT2[2]		GLUT1[2]
Other reabsorption features
