Why is urine cloudy?

Urine can look cloudy when it contains more minerals, cells, mucus, or other particles than usual. Fluid loss from heat, exercise, vomiting, or diarrhoea can concentrate urine and make its appearance stronger. Some foods and medicines can alter colour or smell without causing illness. A urinary tract infection may present with cloudy urine, burning, urgency, frequent urination, lower abdominal pressure, or an unusual odour. Kidney infection is more likely to be considered when urinary symptoms accompany fever, chills, nausea, or pain in the side or back. Cloudiness by itself does not establish a diagnosis.

Think about when the change began and whether you have been drinking less or losing fluids. Drink to thirst unless you have been given a fluid limit. Do not self-treat with leftover antibiotics. If urine becomes clear again and you feel well, continue observing. If cloudiness lasts, recurs, or is joined by urinary discomfort, book a clinical assessment. A urine test can help distinguish infection, blood, crystals, and other findings.

Get prompt care for cloudy urine with fever, chills, pain in the flank or back, vomiting, visible blood, confusion, or inability to urinate. Arrange timely advice if you are pregnant, have diabetes, have kidney disease, or the change continues despite normal fluid intake. These situations may need a urine check and targeted treatment.

Ask what findings would make infection more likely, how to collect a clean urine sample, whether medicines or supplements could affect the appearance, and which changes should lead you to seek same-day care.
