10. Nausea
Renal infection often leads to the development of nausea. One of the primary roles of renal function in the body is the clearance of toxins and other harmful substances. Infected kidneys become highly inefficient at their job, and thus toxins accumulate in the body which may, on occasion, generate feelings of nausea.
Other gastrointestinal symptoms related to kidney involvement during a urinary tract infection include vomiting and diarrhea.
