Normal anion gap acidosis Classification and external resources
ICD-10	E87.2
ICD-9	276.2
DiseasesDB	29144

In renal physiology, normal anion gap acidosis, and less precisely non-anion gap acidosis, is an acidosis that is not accompanied by an anion gap.

[edit] Differential diagnosis

The differential diagnosis of normal anion gap acidosis is relatively short (when compared to the differential diagnosis of acidosis):

• Hyperalimentation
• Acetazolamide and other carbonic anhydrase inhibitors
• Renal tubular acidosis
• Diarrhea
• Ureteroenteric fistula - an abnormal connection (fistula) between a ureter and the gastrointestinal tract
• Pancreaticoduodenal fistula - an abnormal connection between the pancreas and duodenum

It can be remembered with the mnemonic HARD-UP.^[1]

[edit] Causes

The most common cause of normal anion gap acidosis is diarrhea.
