My urine is light yellow cloudy and has a bad odor. but their is no burning, no itching. no other symptoms. what can it be?

Let me explain: If you are other wise healthy, you do not use medications, vitamins supplements and special diets to cause the odor, my suggestion to go and have routine urine test to be sure. There many reasons for bad odor in the urine. Look at web site for more information. Good luck. http://www.mayoclinic.com/health/urine-odor/my00378/dsection=causes.
