Asymptomatic bacteriuria

Asymptomatic bacteriuria is when bacteria are in your urine, but you don’t have any signs of an infection, like pain or fever. It’s common, especially in older adults, and usually doesn’t need treatment unless other problems happen.

You would not know if you have asymptomatic bacteriuria because it doesn’t cause any symptoms.

If you have symptoms like pain, burning, or a stinging feeling when you pee, or if your urine is dark, cloudy, or has a strong smell, you might have a urinary tract infection.

How would I know if I have asymptomatic bacteriuria?

The only way to find out is through a urine test that shows bacteria in your urine, even though you're not feeling sick. It’s often found during routine checks or tests for other health problems.

Should I be concerned about asymptomatic bacteriuria?

Usually, asymptomatic bacteriuria isn’t a problem and doesn’t need treatment. But it could be a concern if you’re pregnant, having surgery, or have health problems like a weak immune system or kidney problems. If you're worried, it’s best to talk to your doctor to see if anything needs to be done.
