Can someone pls clarify the positive and normal gap for me? I dont understand why the body does not balance itself in a positive gap but does in a normal gap (with bicarb and Cl).

Please clarify

So am trying to squeeze my mind to understand what you mean by your question but I could not :(

Please clarify more, what is it exactly that you don't understand!

To be honest im not sure what I am trying to ask either :notsure:
The concept has me memorizing and not understanding.
Always acidosis. yes
Always metabolic. yes
Now why would something like Lactic Acidosis be positive and RTA be normal gap?

thanks

in some diseases the loss of hco3- is balanced by anions of the acid eg lactate so the positive(cations) ions are increasing and the negative (anions ) are decreasing

the equation is( na+) -(chloride ion +hco3-) so as i said above if u think that statement accoding to this equation there is an increase in anion gap

but suppose say in diarrhea loss of hco3- is counterbalance by cl- so they balance each other so there wont be any change in the anion gap

hope u got it
