What causes bladder infections?
Bladder infections are caused by bacteria getting into your bladder. Usually, bacteria get in through your urethra. The urethra is the tube that carries urine from the bladder out of the body.
Women are more likely than men to get bladder infections. A woman's urethra is shorter and closer to the vagina and anus, which makes it easier for bacteria to get to the bladder.
For women, the following also raise the chance of getting a bladder infection:
Having had other bladder infections, especially if they began when you were young

Sometimes you may have a bladder infection but no symptoms. This is more common for older people, people with nerve problems in their bladder, and people who have a catheter in their bladder. Sometimes, in older people confusion is the only symptom of a bladder infection.
How can doctors tell if I have a bladder infection?
Your doctor can tell if you have a bladder infection based on:
Testing your urine
To test your urine, doctors need a sample that doesn't have any bacteria from your skin in it. So before you urinate, you'll have to clean off the area where your urine comes out. You'll first urinate a little bit in the toilet. You'll then put the urine container in your urine stream and collect a sample. If the doctors don't think this method will give a clean enough sample, they may put a catheter in your bladder to get the sample.
