What is it?
Cystitis is inflammation of the bladder, usually identified through an urgent or more often need to urinate, stinging when urinating, blood in the urine or a painful bladder.
This is usually due to an infection in the bladder, which can either be caused by not emptying your bladder properly, damage or irritation around the urethra (the tube that carries urine from the bladder outside the body), or bacteria transferring from the anus to the urethra (either from not wiping properly or intercourse).
Drinking lots of water and cranberry juice can clear up mild cases of cystitis. For more severe cases it is best to see your GP for a course of antibiotics. If your cystitis keeps returning this is often because the infection has not gone. The GP should test your urine before and after a course of antibiotics to make sure the medication has worked.
Urinating before and after intercourse can help reduce infection.
