A fishy smell in pee can result from dietary factors, an infection, and other health issues. It can also be a sign of trimethylaminuria (“fish odor syndrome”) which often has a genetic cause. If fishy-smelling urine is the only symptom, a person may want to wait for a couple of days to see if it clears up.
Fish Odor Syndrome
Also called trimethylaminuria, this genetic condition can give your pee a fishy smell. It happens when your body can't break down trimethylamine. You end up getting rid of the compound through your pee, sweat, breath, and other fluids. It doesn't mean you're unhealthy.
Many of the bacterial species that cause urinary tract infections can also break down urea, a natural waste product that is commonly excreted in urine. These bacteria cause urea to break down into ammonia, which imparts a strong, pungent odor to affected patients' urine.
Urine is mostly waste products and water and normally has a mild smell and a light yellow color. If you have more waste than water in your urine, it can smell more strongly. In most cases, a strong smell isn't a sign of disease. It's usually from your diet and medications, or it means you need to drink more water.
See a GP if: You have smelly pee and: you need to pee suddenly, more often than usual, or during the night. you have pain or a burning sensation when peeing.
A person with uncontrolled diabetes may have blood glucose levels that are dangerously high. The body tries to get rid of the extra glucose in the urine, and this can cause a sweet smell. People with sweet-smelling urine due to diabetes may notice other symptoms, including: exhaustion.
Common causes of a fishy odour include poor hygiene, gingivitis, bacterial vaginosis and urinary tract infections. Advanced kidney or liver disease may also cause this condition.
Liver disease
Infections and diseases of the liver can produce high ammonia levels in the urine and the accompanying pungent odor. Ammonia levels in blood and urine will increase when the liver is not working as it should. Any continued ammonia odor in urine should be checked by a doctor.
Vinegar helps to rid of the toxins that cause the fishy vaginal odour. All you need is 1 cup of vinegar or apple cider vinegar. Add vinegar to your bathtub with water and let it soak in for 20 minutes. You can also drink two tablespoons of vinegar in lukewarm water.
Foul-smelling urine may be due to bacteria. Sweet-smelling urine may be a sign of uncontrolled diabetes or a rare disease of metabolism. Liver disease and certain metabolic disorders may cause musty-smelling urine.
Fishy smells are associated with a type of vaginitis called bacterial vaginosis. Health care providers can prescribe medications to treat it.
If you detect a hint of ammonia in your urine, it could be a sign of a urinary tract infection (UTI).
Bacterial vaginosis (BV) is a common vaginal infection that happens when some normal bacteria that live in your vagina overgrow, causing a bacterial imbalance. Symptoms include an off-white or gray vaginal discharge that smells “fishy.” BV is easily treatable with antibiotics from a healthcare provider.
While some UTIs may go away without antibiotic treatment, Dr. Pitis cautions against foregoing antibiotics. “While it's possible for the body to clear a mild infection on its own in some cases, it can be very risky not to treat a confirmed UTI with antibiotics,” says Dr.
The symptoms of a bladder infection include: Cloudy or bloody urine, which may have a foul or strong odor. Low grade fever in some people.
Trimethylaminuria (TMAU) is an uncommon condition that causes an unpleasant, fishy smell. It's also called "fish odour syndrome". Sometimes it's caused by faulty genes that a person inherits from their parents, but this isn't always the case. There's currently no cure, but there are things that can help.
Pee doesn't usually have a strong smell. But some foods -- especially asparagus, which has a smelly sulfur compound -- can change the odor. So can vitamin B-6 supplements. When you're dehydrated and your pee gets very concentrated, it can smell strongly of ammonia.
Some foods and medications, such as asparagus or certain vitamins, can cause a noticeable urine odor, even in low concentrations. Sometimes, unusual urine odor indicates a medical condition or disease, such as: Cystitis (bladder inflammation)
Several vitamins, including vitamin B-6, can cause urine smell to change. Although a strong smell to your urine probably doesn't mean vitamin D toxicity, it may indicate that you are dehydrated, which can in turn be a sign of excess vitamin D. Strong-smelling urine could also indicate a urinary tract infection.
