This is where acid from the body has built up in the system OR bicarbonate has been lost in excess.

NAGMA-or normal anion gap metabolic acidosis–this is usually due to excessive loss of bicarbonate from the GI tract or kidney failure. It is also known as hyperchloremic metabolic acidosis. Read more.
HAGMA or AGMA-high anion gap metabolic acidosis–this is due to some other acid in the system. Read more.
