ANATOMY

Detailed explanation-1: -UTIs typically occur when bacteria outside the body enter the urinary tract through the urethra and begin to multiply. Most cases of cystitis are caused by a type of Escherichia coli (E. coli) bacteria. But other types of bacteria can cause infections, too.

Detailed explanation-2: -Cystitis is inflammation of the bladder, usually caused by a bladder infection. It’s a common type of urinary tract infection (UTI), particularly in women, and is usually more of a nuisance than a cause for serious concern.

Detailed explanation-3: -A urinary tract infection (UTI) is the most common cause of cystitis.

Detailed explanation-4: -Women are particularly at risk for UTIs because their urethra sits close to the anus, where E. coli is present. It’s also shorter than a man’s, giving the bacteria easier access to the bladder, where the majority of UTIs occur, and the rest of the urinary tract.

Detailed explanation-5: -Most UTIs are caused by E. coli that live harmlessly in the gut. However, when shed in the feces, the bacteria can spread to the opening of the urinary tract and up to the bladder, where they can cause problems.
