A UTI (urinary tract infection) happens when bacteria enter the tube where pee comes out. You feel like going to the bathroom all the time and it might sting. Drinking plenty of water is the best medicine to prevent it! If it happens, the doctor prescribes a little medicine and it soon passes. It's important to always wipe from front to back after using the bathroom to prevent bacteria from getting near the urethra. Small hygiene habits make all the difference for your health!
