Urine odor refers to the scent of your urine as you excrete it from your body. Urine odor varies — ranging from sweet to foul.
Urine odor is related to the volume and concentration of a variety of chemicals excreted by the kidneys. Normally, diluted urine has little to no odor. If your urine becomes highly concentrated, urine odor may have a strong ammonia quality. Many foods and medications — such as asparagus or certain vitamins — also can affect the odor of urine.
Sometimes, unusual urine odor indicates an extremely rare condition, such as the inherited disorder called maple syrup urine disease.
