Causes of UTI
UTI occurs due to the presence of bacteria in the urine. This usually happens when bacteria inhabiting the area around rectum and vagina get into the urine through urethra and travel upwards to the bladder. The infection can spread as the bacteria travel up to the ureters and enter the kidneys to infect them. Urinary system is built to keep such microbial invaders away but oftentimes, due to a fault in the defence system, these bacteria can take hold and cause a full-blown infection anywhere in the urinary tract. The most common organism that causes UTI is E.coli, this bacteria inhabits the GA tract and can gain entry into the urinary tract due to close proximity of anus to urethra, specially in females.
UTIs can also occur due to conditions such as Kidney stones, stroke, trauma, or any other cause that can delay bladder emptying or effects urinary outflow.
