Acute cystitis occurs when the lower urinary tract (urethra and bladder) become infected by bacteria. Most cases are caused by Escherichia coli (E. coli), a bacteria found in the intestines. When you urinate, you help remove bacteria from the bladder. However, sometimes the bacteria grow so fast that some remains in the bladder.
Cystitis is rare in men. Women are more likely to have cystitis. It is much easier for the bacteria to travel into a woman's bladder, because it does not have to travel as far.
The condition is very common, and most often affects sexually active women age 20 to 50. Sexual intercourse may increase the risk of cystitis.. However, the infection may also occur in those who are not sexually active.
