Urine odor refers to the smell from your urine. Urine odor varies. Most of the time, urine does not have a strong smell if you are healthy and drink plenty of fluids.
Most changes in urine odor are not a sign of disease and go away in time. Some foods and medicines, including vitamins, may affect your urine’s odor. For example, eating asparagus causes a distinct urine odor.
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 conditions that can cause changes in urine odor include:
- Bladder infection
- Body is low on fluids (concentrated urine can smell like ammonia)
- Poorly controlled diabetes (sweet smelling urine)
- Liver failure
