The acid-base balance of the body is regulated by the lungs and the kidney.
The lungs remove carbon dioxide and the kidneys resorb filtered bicarbonate and excrete hydrogen ions, to remove the daily acid load produced by metabolism of dietary protein, amongst other things.
The Renal Tubular Acidoses (RTAs) are a group of disorders in which there is a failure of the kidney to either resorb bicarbonate or excrete hydrogen ions which is not related to advancing renal failure. They are a cause of a normal anion gap acidosis.
[edit] Types
There are several different subtypes of RTA;
- Distal or type 1 RTA
- Proximal or type 2 RTA
- Hypoaldosteronism or type 4 RTA
