Causes. Urine odor is related to the volume and concentration of a variety of substances excreted by the kidneys. Normally, urine that contains a lot of water has little to no odor.

Many foods and medications, such as asparagus or certain vitamins, can affect the odor of urine. Sometimes, unusual urine odor may indicate a medical condition or disease, such as: 1  Bladder infection. 2  Cystitis (bladder inflammation). 3  Dehydration. 4  Diabetic ketoacidosis (high levels of blood acids called ketones). 5  Gastrointestinal-bladder fistula (abnormal connection between the intestines and bladder).
