Cloudy urine has many potential causes. Some of these causes are more serious than others, making it important to understand when you need to seek medical attention.

Normal urine comes in many colors. It typically varies from clear (like water) to a dark amber color. The exact shade of urine is a function of many different factors, including your level of hydration, what you've eaten lately and medications you are taking among other things. Changes in urine color and clarity can often be worrisome, especially when combined with other urinary symptoms, such as increased frequency and pain or burning on urination.

Pylonephritis will almost always be associated with flank pain, pain on urinating as well as fever and general symptoms of infection.

Bladder infections, known as cystitis, can cause cloudy urine. In these cases the cloudiness is usually due to white blood cells (leukocytes) in the urine, which are a response to the infection. A quick urine dipstick test at the doctors office can establish the presence of white cells in the urine. Most cases of cystitis have other symptoms as well. These can include a feeling of urgency, frequent urination, pain or burning on urinating, abdominal pain, and even fever or chills.
