A UTI, or urinary tract infection, is when bacteria (germs) get into your urinary system, which includes your bladder, kidneys, and the tubes that connect them. It can make you feel like you really have to pee a lot, even if not much comes out. It might hurt or burn when you go, and your tummy might ache too. UTIs are common and can happen to anyone, but they’re more common in females. Drinking plenty of water and taking prescription antibiotics can help you feel better and get rid of the infection.
