They’re caused by bacteria that enter your urethra and wreak havoc through your urinary tract system. The urethra is a tube that transports pee out of the bladder — kind of like an Ancient Roman aqueduct, but in your vulva.
In severe cases, the bacteria travels further through your urinary system and causes a kidney infection.
Many types of bacteria cause UTIs, but the most common culprit is E. coli, which is responsible for nearly 90% of infections. E. coli usually lives its best life in your intestinal tract but occasionally finds its way from your bum to your urethra and causes a bladder infection. Yes, we mean poop.
For folks with vulvas, this journey is a short one, and it’s easy for poop particles to wander up the road and accidentally infiltrate the urinary tract.
Once the bacteria enters your urethra, it starts to multiply and thus, the dreaded UTI is born.
