N30: Cystitis

N30.0: Acute cystitis

The bladder sits low down in the abdomen and collects the urine. The urine is produced in the two kidneys. The urine flows from the kidneys into the bladder via the ureters. When you pass water, the urine flows from the bladder via the urethra and out. The inside of the bladder is lined with a protective mucosal layer.

Your bladder has become inflamed as a result of pathogens. People are at a higher risk of bladder inflammation following intercourse, for example.

People with an inflamed bladder can experience pain when urinating. It also possible that you will have a frequent urge to go to the toilet. You may only be able to pass a small amount of urine. The urine can also be bloody or cloudy if you have a bladder infection.
