Urinary tract and bladder conditions It may seem obvious, but issues with your urinary tract and bladder are some of the most common conditions to cause frequent urination. Urinary tract infections (UTI), in particular, are the most common cause of frequent urination. During a UTI, an outside infection enters the body and causes inflammation (swelling) in your urinary system. Urine is produced by the kidneys and travels through the ureters to the bladder to be stored. The bladder is basically a muscular sac that holds urine until it is ready to be released into the urethra, the tube that connects the bladder to the outside of the body. At the same time the bladder contracts, the urinary sphincter relaxes.
