The doctor is an ancient profession and relatively recently it has not yet smelled of alcohol and penicillin, but smelled of urine and faeces. Doctors had to assess the body’s odour, colour, taste and consistency. For example, in old reference books you can find a mention of the smell of approaching death. We will move to the 17th century thanks to the painting by Jan Sten, where the doctor visually assesses the patient’s urine:
What illnesses could a doctor diagnose with such a meager set of characteristics of a patient’s natural dispatches? Naturally, at first the doctor preferred to evaluate the object of the study from a distance – the appearance. We will start with it.
The coloring of both urine and faeces has a common origin. Yellow-brown pigments are products of blood hemoglobin decay. In the case of liver disease, the most common cause of discoloration is faeces, and the change in urine colour can be a consequence of both kidney and liver pathology. The presence of traces of blood is a sign of either intestinal bleeding due to cancer or ulcers, or a sign of serious kidney injury.
Sediments in the urine form white blood cells as a result of kidney or bladder infection. Fine sand indicates the possibility of ureteral stones.
The smell of urine with acetone is a good sign of diabetes mell. Ammonia is a bacterial bladder infection. Rotten meat – bladder tumor. It was also the violets that smelled when they tried to poison themselves with turpentine in the olden days.
The smell of feces causes the metabolism products of bacteria – stingray, indole, hydrogen sulfide, etc. A slight shift in the ratio of these gases has a noticeable effect on odor perception. The shift towards hydrogen sulfide will give a smell of rotten eggs that is characteristic at infringement of rotting of fibers. Disruption of processes of fermentation of carbohydrates will give acidic smell of indole. If, however, completely eliminate hydrogen sulfide, it will smell like jasmine, as the skatole and indole are synthesized by the flowers of this plant. All these are signs of dysbacteriosis. Yes, these gases are combustible and explosive!
Fecal consistency characterizes peristalsis activity and water absorption processes.
Fecal form. “Feces” – disturbance of colon tone and/or excessive growth of lactobacillus colonies. “Horseshoe” feces – a sign of rectal tumor.
