Mistakenly drinking a mouthful of urine generally has no effect on your health. The main component of urine is water, followed by metabolic wastes such as urea, uric acid, creatinine, etc., and a small amount of inorganic salts such as sodium ions, potassium ions, chloride ions and so on. Urine after oral intake, will be absorbed through the gastrointestinal tract, the main possible harm to the body is the metabolic waste, but in the case of normal renal function, these wastes will soon be discharged with the urine, to the extent that it does not affect the health. Therefore, drinking small amounts of urine has no effect on the health of the organism, but this is generally not recommended. Only in cases of extreme dehydration can drinking urine provide the organism with a small amount of water and electrolytes that may save lives. It should be noted that if a urinary tract infection is present, pathogens can be present in the urine, and drinking it at this time may lead to a gastrointestinal infection, which in turn requires antibiotic treatment.
