Why does my urine have a sour smell?

Hello. Thank you for writing.

Most of the medical information would suggest that just because your urine smells odd, in this case sour, does not necessarily mean there is something wrong. Many foods such as onions or asparagus can alter the odor of urine. Medications or supplements that you take may also have an effect on the smell or color too. A urinary tract infection or other medical conditions can also cause urine to have an order of some sort.  If the smell is something new and lasts more than a few days, see your doctor.
