Renal tubular acidosis Type 1 pathophysiology
Distal failure of H+ secretion -> Acidaemia -> Metabolic acidosis
K+ excretion to maintain electrochemical gradient in kidney -> hypokalaemia
Renal tubular acidosis Type 2 pathophysiology
Failure to reabsorb bicarb in proximal tubule -> acidaemia -> metabolic acidosis
High urine bicarb -> osmotic diuresis -> hypovolaemia -> RAAS activation -> Aldosterone -> Increased Na resorption + decreased K resorption -> hypokalaemia
Renal tubular acidosis Type 4 pathophysiology
Deficiency of(Addison’s)/Resistance to Aldosterone (ARBs) -> the normal stuff -> hyperkalaemia and acidosis
