10 Causes of Kidney Infection
Cause #1: Kidney Stones
Kidney stones, or renal stones, occur when solid material remains and builds up in the urinary tract. The material exits the body via the urinary tract out of the urethra. While some individuals experience no symptoms due to smaller stones, stones that are bigger than 5 millimeters can cause blockage in the urinary tract leading to severe pain in the loin or groin, lower back pain, blood in the urine, nausea, vomiting, dysuria, and more.
Risk factors of kidney stones include dehydration, obesity, high levels or calcium in the urine, etc. In case of obstruction, a urinary tract infection (UTI) may occur due to accumulation of bacterial growth in the stagnant urine. From the urethra, the infection can spread upwards toward the bladder, ureters, and kidneys, causing a kidney infection.
