Urine with a simple yellow odor usually only lasts a few days and goes away on its own. However, if combined with other symptoms such as painful urination, burning urination, persistent foul odor, etc., you should see a doctor because it could be a sign of a urinary tract infection.

Not everyone pays attention to the color of urine, but in fact, observing abnormal urine colors also helps doctors make clinical diagnoses. If you see dark yellow, clear, or any other unusual color urine for a long time, you should go to the hospital for a check-up soon.
