What is (are) Urinary Tract Infections ?
A Common Problem With Aging Urinary tract infections (UTIs) are a common bladder problem, especially as people age. UTIs are the second most common type of infection in the body. Each year, UTIs cause more than 8 million visits to health care providers. UTIs can happen anywhere in the urinary system (which includes the kidneys, bladder, and urethra). But UTIs are most common in the bladder. A UTI in the bladder is called cystitis. Infections in the bladder can spread to the kidneys. A UTI in the kidneys is called pyelonephritis. Sometimes, a UTI can also develop in the urethra, but this is less common. A UTI in the urethra is called urethritis. Some UTIs Lead to Severe Problems Most UTIs are not serious. But some UTIs, such as kidney infections, can lead to severe problems. Bacteria from a kidney infection may spread to the bloodstream, causing a life-threatening condition called septicemia. When kidney infections occur frequently or last a long time, they may cause permanent damage to the kidneys, including kidney scars, poor kidney function, and high blood pressure.
