What is a common characteristic of cloudy urine?

Cloudy urine is often associated with the presence of various substances that can alter its appearance. This turbidity may result from the presence of cells (such as white blood cells or red blood cells), bacteria, proteins, crystals, or other elements. These substances can be indicative of a range of conditions, including urinary tract infections, kidney stones, or other pathological states. It is important to evaluate the context and other accompanying symptoms to determine the underlying cause of the cloudiness.

Other options suggest more specific interpretations of cloudy urine. While dehydration can cause urine concentration and potential cloudiness, it is typically related to a darker, not necessarily cloudy, appearance. Proteinuria indeed can lead to cloudy urine, but it is not the sole cause. Furthermore, though cloudy urine can be associated with urinary tract infections, it is not a definitive sign, as cloudiness can arise from several other factors.
