However, the term cystitis is only used to refer to infections that are located in the bladder.
Cystitis is much more common in women than in men, probably because the urethra that leads to the bladder from outside is shorter. It is generally mild and the symptoms usually clear up by themselves within a few days. If they do not, you should see a doctor as there is a risk that the infection could spread into the kidneys. You should also see a doctor if you experience cystitis symptoms very often, you are pregnant, or if you are a man and you think you have cystitis or a UTI.
