Cystitis is inflammation of the bladder, usually caused by a bladder infection. It's a common type of urinary tract infection (UTI), particularly in women, and is usually more of a nuisance than a cause for serious concern. Mild cases will often get better by themselves within a few days. However, some people experience episodes of cystitis frequently and may need regular or long-term treatment.

What is Cystitis? 

In most cases cystitis is caused by intestinal bacteria resulting in the inflammation of the bladder.

Although our bodies naturally contain bacteria (natural flora) with no problems, the introduction of new bacteria, or where current bacteria or natural flora are given the opportunity to grow can result in infection. 

Women are more likely to be affected by cystitis than men. This is due to the fact that a female’s urethra, a tube through which urine passes from the bladder and out of the body is far shorter than a males, thus allowing bacteria to pass to the bladder far more easily.

Symptoms of cystitis:

  • Burning sensation or pain on urination.
  • Urinating more frequently.
  • Foul-smelling or cloudy urine.
  • Pain directly above the pubic bone.
  • Children under the age of five years often have less definite symptoms i.e. weakness, irritability, reduced appetite and vomiting.
  • Older women may only present with weakness, falls, confusion or fever.
  • Blood may pass in the urine
