​
Most of the time, urine is see-through. It is not necessarily abnormal to have cloudy urine, though. There are both harmless and dangerous possible causes of it.

One cause that is harmless is when you have a buildup of phosphates in your urine. This will make it appear cloudy instead of clear. This can occur due to the foods you ate. Your urine should return to normal within a day or two.
​
Urinary tract infections (UTIs) can cause cloudy urine. Usually, a UTI will have other symptoms, like frequent urination, urinary pain or a constant urge to urinate. It is possible, though, for a UTI to have no other symptoms. The only way to find out if you have a UTI is to consult with a doctor and have your urine tested.

What Causes Cloudy Urine?

Cloudy urine can come from excessive protein in the urine. This is called proteinuria. It can be caused by high blood pressure, kidney diseases and in pregnant women, it may be a sign of pre-eclampsia.
​
In men, inflammation of the prostate (prostatitis) can cause cloudy urine. It usually also causes more noticeable symptoms, such as pain, fever and chills. If you suspect you have prostatitis, you should see a doctor.


Some sexually transmitted diseases may cause your urine to look cloudy. Gonorrhea in particular is known for causing this.

Pus or vaginal discharge in urine can make it look cloudy.
