Bladder infections

The bladder is part of the urinary system. It is a sac in which urine  is collected from the kidneys, and it contracts (squeezes in) when you urinate.

The bladder can be infected with bacteria, viruses, fungi or parasites. Bladder infections can, more rarely, be caused by an infected object coming into contact with the bladder, for example through a catheter (drainage tube) that is passed into the bladder, during treatment for another condition.

A bladder infection is a type of urinary tract infection (UTI). One of the main symptoms of a bladder infection is cystitis, which is painful irritation and swelling of the bladder.

See topics on Urinary Tract Infection and Cystitis for further information on these conditions.
