Urinary tract infections (UTIs) happen when bacteria get into the urethra and travel up into the bladder. They are among the most common infections in people, and antibiotic treatment is usually helpful in treating an infection.
If the infection stays just in the bladder, it is a called “cystitis.” Common symptoms include pain or burning when urinating, urinary frequency or urgency, blood in the urine. Treatment will usually require a 3-5 day course of antibiotics.
But if the infection travels up past the bladder and into the kidneys, it is called “pyelonephritis.” Common symptoms include fever, flank pain, nausea, and vomiting. Treatment will usually require a 7-14 day course of antibiotics.
