Kidney infection, also known as renal infection or pyelonephritis, happens when bacteria from the urinary tract travel up the urethra and affect one or both kidneys.
Most of the time, the bacteria that cause kidney infections come from another part of the urinary tract, such as the bladder, ureters, or urethra.
Kidney infections most commonly affect people who already have a bladder infection, females, and pregnant people.
People who experience the symptoms of a kidney infection should seek medical attention as soon as possible, as the condition may cause permanent kidney damage or spread to other parts of the body.
