Cloudy urine that smells like ammonia

Urine develops a stronger ammonia smell when it becomes concentrated or sits for a while, such as after waking or when fluid intake has been low. Foods, supplements, and some medicines can also change urine smell. Cloudiness may come from crystals, mucus, or cells, so the two changes may have a shared cause or may occur independently.

A urinary tract infection can produce cloudy or strong-smelling urine and may also cause burning, urgency, frequency, or lower abdominal discomfort. Kidney infection may present with fever, chills, nausea, and side or back pain. Smell alone cannot diagnose an infection.

Drink fluids normally if you have not been told to limit them, then notice whether the smell and cloudiness persist in fresh urine. Avoid scented products around the genital area, which can irritate skin and confuse the source of an odour. Record burning, urgency, pain, fever, discharge, and any recent medicine or supplement changes.

Arrange a medical review if the change continues, returns repeatedly, or occurs with urinary symptoms. A clinician may request a clean urine sample and decide whether testing for infection or other causes is needed. Do not take leftover antibiotics.

Seek prompt care for ammonia-smelling cloudy urine with fever, chills, side or back pain, vomiting, visible blood, or increasing discomfort. Get urgent help if you are confused, faint, severely weak, unable to pass urine, or unable to keep fluids down. Pregnancy and known kidney disease warrant early clinical advice.

Ask whether a fresh sample should be tested, whether the findings suggest infection, and which symptoms require same-day review. Tell the clinician when the smell began, whether it changes after drinking, and about supplements, medicines, discharge, pain, or fever.
