what causes urine odor
Underlying Medical Causes of Urine Odor. Several conditions can cause strong or unusual urine odor. The most common causes include: Dehydration. Dehydration occurs when you do not drink enough fluids. If you are dehydrated, you may notice that your urine is a dark yellow or orange color and smells like ammonia.
The presence of bacteria in the urine, such as with a urinary tract infection (UTI), can affect the appearance and smell of urine. When there is an infection in the urinary tract, the urine may take on a foul-smelling odor as well as appear cloudy or bloody.
