Is cloudy urine always a sign of infection?

Possible infection: Cloudy urine can be caused by an infection, kidney damage, protein in the urine, and sediment from a stone. See your doctor for confirmation and possible treatment.

For gals: Cloudy urine can also be caused by vaginal discharge. Lots of things to talk with your doc about!

Certainly not: Can be due to so called "amorphous debris" which is innocent sediment often found in alkaline urine. Chyluria can also cause a milky cloudy urine. Chyle is a substance comprising lymph plus fatty material. Can occur during pregnancy and number of other medical conditions permitting lymph to leak into the urine. Utis are usually symptomatic, but, not always.
