Cystitis is a disease which is caused by the inflammation of bladder. This is due to the infection of the micro organism, which can be either virus or bacteria. A particular bacterium responsible for this is E.Coli. The person affected by this disease feels a painful sensation during urination. The bacteria in the urinary track become active and inflame it entirely. This disease is more common among women than men. This is because of the short length of the urethra and the closeness of the urethra to the vagina and anus, where bacteria are commonly found. There are several types in this. They are Traumatic cystitis, interstitial cystitis, eosinophilic cystitis, adiation cystitis, hemorrhagic cystitis. Though antibiotics have the speciality of clearing the bacteria, it is not widely use. It is because of its inability to penetrate in completely. The best remedy for this is to drink 8 glasses of water every day.
