How Common Are Bladder Infections?

What Are Bladder Infections?

Bladder infections are a common reason for patients to visit their doctor. Many visits each year are attributed to infections in the urinary system, with most due to bladder infections. The urinary tract is compromised of the kidneys, ureters (connecting the kidneys to the bladder), the bladder (where urine is stored), and the urethra. Bladder infections (also known as cystitis) are the most common infections of the urinary tract, and the term UTI (urinary tract infection) is sometimes used interchangeably with bladder infection. The symptoms of a bladder infection usually include pain upon urination, frequent urination, and the feeling that you need to urinate even if your bladder is not full.

Bladder infections are more common in women than men and can occur at any age. Bladder infections are especially worrisome in infants (as the infection can spread into the bloodstream), the elderly, and people with other medical conditions (especially those that suppress your immune system such as diabetes). If the bladder infection spreads, it can affect the kidneys (pyelonephritis) or even get into the bloodstream.
