What should you know about urine that smells like eggs and looks cloudy?

A sulfur-like smell may follow foods or supplements that contain sulfur compounds, and some medicines can alter urine odour. Concentrated urine from dehydration can also smell stronger and appear darker or cloudy. If the change persists after a likely food or medicine trigger has passed, it deserves closer attention.

Cloudiness with burning, urgency, frequent urination, lower abdominal discomfort, or blood can occur with a urinary tract infection. Fever, chills, nausea, or pain in the side or back can signal infection higher in the urinary system. The appearance and smell alone cannot identify the cause.

Think back to recent foods, supplements, medicines, fluid intake, and the timing of the change. Drink normally unless a clinician has given you a fluid restriction. Do not use leftover antibiotics or rely on odour alone to choose treatment. A clinician may request a clean-catch urine sample, dipstick, microscopy, or culture depending on your symptoms.

Tell the clinician about discharge, pregnancy, recent sexual activity, previous urinary infections, and any kidney problems. These details help distinguish urinary causes from contamination or another source of odour. The [Cloudy Urine](/symptoms/cloudy-urine/) guide has related symptom information.

Arrange a medical review if the smell and cloudiness continue, recur, or occur with burning, urgency, pelvic pain, or blood. Seek urgent care for fever with side or back pain, vomiting, shaking chills, confusion, or severe weakness. These symptoms can occur with a kidney infection and should be assessed promptly.

Ask whether the pattern fits dehydration, a food or medicine effect, or a urinary tract infection; whether you need a urine test or culture; and which changes require urgent care. Mention any fever, flank pain, burning, discharge, blood, or difficulty passing urine.
