Question Bicarbonate and Chloride in Laxative Abuse!

Hi all:

Just a short question, if patients come in with laxatives use and we diagnose factitious diarrhea, then the serum bicarbonate should be LOW, right? Because there is a chart in UW comparing some hypokalemia condition. And in factitious diarrhea, it says the serum bicarbonate is HIGH.

Besides, with diarrhea, our urine chloride ill be low or high? I think it would be high because in diarrhea we have metablic acidosis so we have to urinate more hydrogen and chloride?

Thank you!

HCO3-
primarily pancreatic secretion
Lost in diarrhea.
Hence gives metabolic acidosis

so LOW HCO3-


Cl-
other anion in the body.
the loss of one anion causes the kidneys to compensate and hold back the other anion.
so HIGH Cl-
