What Causes Cloudy Urine in Women and Men?

Healthy urine is clear and light yellow in color. Urine may appear cloudy for a variety of reasons, some of which are not harmful, such as foaming of the urine that occurs temporarily when urinating rapidly. However, when urine is persistently cloudy, hazy or milky, it is generally an abnormal condition and a symptom of an underlying disease, disorder or condition.

Cloudy Urine

Cloudy urine can be caused by a variety of conditions, including vaginal discharge, sexually transmitted diseases, dehydration, certain autoimmune disorders, as well as infection, inflammation, or other conditions of the urinary tract (kidneys, ureters, bladder and urethra). Cloudy urine can also be caused by diseases that affect other body systems in addition to the urinary tract. These include diabetes, preeclampsia and heart disease.

Cloudy urine can occur in all age groups and populations, and it may or may not occur with additional symptoms, such as a foul urine odor and burning with urination.

In some cases, cloudy urine can be due to a serious or life-threatening underlying disease, such as pyelonephritis and urosepsisSeek prompt medical care if you have persistently cloudy urine. Timely diagnosis and treatment of the underlying cause reduces the risk of serious or life-threatening complications, such as kidney failure and shock.

If you have cloudy urine with symptoms such as high fever (higher than 101 degrees Fahrenheit), abdominal or flank pain, bloody urine, or a change in consciousness or alertness, seek immediate medical care (call 911).
