I don't understand how for example in elevated anion gap acidosis really "causes acidosis" when the concentrations of cations and anions are actually the same (as we see in the box). Aren't they?? :(
The left figure is normal , While the concentration of the right one is changed, An example of elevated anion gap is accumulation of Lactic Acids which is dissolve to Lactate anions and H+ ions , That's lead to decrease HCO3 due to buffer excessive H+ ions in plama , While Lactate anions Categorie as UA , That's lead to increase UA in right figure.
