Cystitis is inflammation of the bladder, more commonly referred to as a bladder infection, according to Mayo Clinic. This condition has many possible causes, the most frequent being a bacterial infection called a urinary tract infection.
UTIs are often caused by external bacteria, such as E. coli, entering the body and reproducing, but may also be caused by sexual intercourse, states WebMD. Cystitis may also be caused by medications such as those used in chemotherapy, radiation, catheter use, hypersensitivity to certain chemicals or due to other health problems such as diabetes or kidney stones.
Symptoms of cystitis include a strong urge to urinate; a burning sensation during urination; bloody, cloudy or strong-smelling urine; feeling pressure in the lower abdomen; and a low fever, notes Mayo Clinic. Cystitis is diagnosed using a urine sample, possibly followed by a bacterial culture or by a cystoscopy, where a thin tube with a camera is inserted through the urethra and into the urinary tract.
Cystitis is treated in different ways dependent on the cause of the infection, explains Mayo Clinic. If it is caused by a bacterial infection, for example, antibiotics are the treatment. If the infection is a result of sensitivity to chemicals, it may be suggested to avoid the chemical causing the reaction.
