Fecal Nitrogen

The quantification of nitrogen in feces is mainly used for nitrogen balance test and diagnosis of small intestinal malabsorption. In small intestinal malabsorption, nitrogen excreted in the feces increases. In addition, in severe diarrhea, gastrocolonic fistula also increased. Fatty diarrhea (oral inflammatory diarrhea, spontaneous diarrhea, celiac disease) can increase to 214mmol / 24h, and pancreatic diseases (chronic pancreatitis, pancreatic duct obstruction, post-pancreatectomy) can excrete up to 214 to 643mmol / 24h nitrogen.
