Urine is made up of water and a small concentration of waste products. Urine typically has a subtle odor of its own, but this can change or fluctuate for a number of reasons. In some cases, your urine may even take on a fishy smell. Although this is usually temporary and easily remedied, it can sometimes be a sign of an underlying condition that requires more advanced treatment.


  1. Diet and dehydration

Your urine contains some of the chemical compounds found in food you’ve recently consumed. These compounds will carry some of the food’s scent into your urine. With that in mind, it’s unsurprising that eating fish can cause your urine to have a fishy smell.

Other foods and drinks that can cause this include: caffeine, which can act as a diureticasparagus, which can release of sulfur in the urine Brussel sprouts and cabbage, which release methyl mercaptan that can cause a strong fish or rancid smell

Dehydration can also cause or aggravate the fishy smell in your urine. When you’re dehydrated, there’s less water to dilute the concentrations of chemicals. This will give your urine a stronger smell.

  1. Urinary tract infection (UTI):-

A UTI can cause bacteria from the infection to contaminate the urine, resulting in a distinct fishy smell. UTIs are more common in women than men.

Other symptoms include:

  • urine that is cloudy or bloody
  • pain or burning during urination
  • feeling the need to urinate urgently or frequently
  • lower abdominal or back pain
  • mild fever.
  1. Bacterial vaginosis: -

Bacterial vaginosis occurs when there is too much “bad” bacteria in the vagina, disrupting the balance of “good” and “bad” bacteria. This can cause a grayish, fishy-smelling vaginal discharge that may be noticeable when urinating.

Some women with bacterial vaginosis won’t experience any symptoms.

If symptoms are present, they may include:

  • discharge that is thin or watery
  • pain during intercourse
  • painful urination
  • light vaginal bleeding.
  1. Trimethylaminuria:-

Trimethylaminuria is a rare metabolic disorder that occurs when the body is unable to break down certain compounds properly. This includes fishy-smelling trimethylamine. Trimethylamine is produced in the intestines after consuming certain types of food that are high in protein. With trimethylaminuria, trimethylamine is released into the urine instead of being broken down.
