Everyone's urine has ammonia in it. The more hydrated you are, the less concentrated the ammonia is. But when you're dehydrated, the ammonia concentration is stronger — and so is the smell. This is why you may notice your urine smells stronger in the morning right after you wake up.
some people find that their urine smells stronger and is darker first thing in the morning (this is when it's more concentrated, or generally when they're dehydrated) certain food and drinks, including asparagus, beer, garlic and coffee, may temporarily give urine a stronger smell.
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.
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) Dehydration.
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.
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.
Cystitis
It's often caused by a bacterial infection, such as a UTI. The bacteria from the infection can result in a strong fish smell in the urine.
It's usually caused either by a UTI or an imbalance of “good” and “bad” bacteria naturally found within the body. When caused by bacteria, the bacteria will affect the urine as it sits in or passes through the bladder. This can lead to strong, sulfur-smelling urine.
Concentrated urine
When urine is highly concentrated, it contains more ammonia and less water. This can cause it to have a strong smell. Urine tends to be more concentrated when a person is dehydrated. This is often the case first thing in the morning or when a person does not drink enough water throughout the day.
You're dehydrated. If you're not drinking enough water, your pee will take on a strong ammonia scent. Without enough H2O to dilute your urine, it becomes more concentrated with waste products and therefore, darker in color and more odorous. Drink more water, and the smell should go back to normal.
Specifically, saliva production decreases while you're sleeping, leaving you with dry mouth at night. Since saliva usually flushes out odor-causing particles, you're left with bacterial buildup that makes its presence known with its distinctive aroma.
Symptoms of kidney infection
These include: needing to pee suddenly or more often than usual. pain or a burning sensation when peeing. smelly or cloudy pee.
Another indicator that you could have a bladder infection is that your pee strongly smells when you urinate. While your pee may always smell differently if you drink a lot of coffee, you'll notice a particularly different smell if you have a bladder infection. It will have an off or funny smell that you aren't used to.
Why does my urine smell like fish? Patients affected by trimethylaminuria will often have fishy-smelling urine. Trimethylaminuria is a genetic disorder in which affected individuals have an enzymatic deficiency that makes them unable to metabolize TMA.
Diabetes: Strong sweet-smelling urine is a sign of advanced diabetes, which can be diagnosed with urinalysis. With advanced diabetes, sugar and ketones, which are normally absent, can accumulate in the urine and create a strong odor.
Kidney disease causes chemicals in urine to become concentrated and to cause a smell resembling ammonia. Kidney dysfunction can also cause high bacteria and protein levels in the urine, which will contribute to a foul ammonia smell.
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.
Regular urine color ranges from clear to pale yellow. But certain things can change the color. Foods such as beets, blackberries and fava beans can turn urine pink or red, for example. And some medicines can give urine vivid tones, such as orange or greenish-blue.
Urine that smells like feces could mean that there's a connection (called a “fistula”) between the rectum and the bladder or urethra. Some vaginal infections have an odd odor that women tend to notice when they urinate.
One such example is a sweet smell to the urine, which can indicate excess glucose (blood sugar) in the urine. Another is the smell of ammonia, which has a strong, chemical-like smell.
