What is a UTI?

A UTI is an infection of the urinary tract; most commonly caused by bacteria that are normally found in the digestive tract called Escherichia coli (E. coli) that mistakenly finds its way into the bladder or urethra.

How common are UTIs?

Up to 70% of women will experience a UTI in their lifetime, of this group up to 30% will go on to suffer recurrent UTIs.1 However, only 5% of men will experience a UTI in their lifetime.2

UTIs are more common in women than men. This may be partly due to differences in anatomy; the female urethra is very short (around 4 cm), so bacteria can more easily make their way into the urinary tract.
