Why does urine smell so bad?

Urine is an important part of the human circulatory system. It can expel excess water and useless products of metabolism from the body. Under normal circumstances, urine has no odor, but some people have very smelly urine. This situation is most likely due to a disease in the human urinary system, and people need to pay special attention to it. The following is a detailed introduction to the reasons why urine smells bad.

Urine odor: Generally speaking, urine contains urea, which will give off a slight odor. When urine is left for a long time, the urea may decompose and give off an ammonia odor. However, if freshly discharged urine has a very obvious odor, there may be problems such as urinary tract infection or urinary retention. In addition, eating certain foods such as onions and garlic can also make the urine have a special smell. The following diseases can also cause urine odor: Urethritis caused by non-sexual behavior, such as traumatic mental stimulation, systemic infection complications, metabolic abnormalities, allergies, etc.

Urethritis caused by sexual intercourse or similar sexual activities. Gonococcal urethritis is urethritis caused by infection with gonorrhea. Non-gonococcal urethritis is a urethritis caused by microorganisms other than gonococci, including chlamydia, mycoplasma, etc. If urethritis is not treated in time, it can easily cause prostatitis, orchitis, epididymitis, seminal vesiculitis, etc. Urine may also have an ammonia smell. The volatile acid in normal urine may produce an ammonia smell due to the decomposition of urea by bacteria after being left. If the urine has an ammonia smell as soon as it is discharged, it often indicates chronic cystitis and chronic urinary retention.

The apple scent is often seen in diabetic acidosis or hunger, and this kind of urine can often attract ants to gather. A putrid, fishy smell is common in cystitis and suppurative pyelitis.
