Urine analysis

The suspicion on bacterial growth in the intestine is based on how it has started, but also on bacterial findings in faeces.

Clinically this phenomenon, also called ”bacterial overgrowth”, is often accompanied by meteorism and diarrhoea but also by dermatological problems. This is caused by an affected digestive ability which can be followed by inflammatory and destructive mucosal changes. The causes can be the following:

  • Sub- or anacid stomach
  • Excessive amount of indigestible proteins and/or carbohydrates
  • Segmental disturbances of the intestinal motility with decelerated intestinal passage
  • Excretory pancreas insufficiency

Due to the increased number of bacteria in the gut, too many bacterial metabolites from nutritious substances arise. These metabolites are detoxified in the liver and excreted via the kidneys.

The quantitative evidence of phenols in night- and morning urine with increased values is a reliable indicator of an overgrowth of the intestine.

Through a particular analysis of nitrosonaphtol and indican it is furthermore possible to locate a growth in the intestine. Whilst phenol mainly is resorbed in the small intestine, indican is a bacterial metabolic product which is resorbed in colon.

Normal value phenol: < 70 mg/dl urine
Indication of bacterial overgrowth of the small intestine: > 70 mg/dl urine

Normal value nitrosonaphtol: < 0,1 dE
Indication of bacterial overgrowth of the small intestine: > 0,1 dE

Normal value indican: 1,0 to 3,0 mg/dl urine
Indication of bacterial overgrowth of colon: > 3,0 mg/dl urine
