Causes of Abnormal Smell (Odor) or Color of Your Urine (Pee)
Abnormal smell and/or color of your urine can be caused by an array of factors. Urine excreted by an otherwise hydrated healthy person does not usually have a strong smelly odor and its appearance is straw-like in color.
Some foods, vitamin supplements and medications may cause a noticeable change in your urine, for example, asparagus causes an abnormal urine odor.
Your pee odor or color changes may be only temporary, so don’t automatically assume it is a sign of a disease, condition, or infection.
