Sometimes — but it's a gamble
A small number of very mild bladder infections do settle on their own as your immune system and fluids flush out the bacteria. However, you can't reliably tell in advance which UTIs will resolve and which will get worse, so waiting it out is a gamble.
The main risk of waiting is that a simple bladder infection can spread up to the kidneys, which is a much more serious infection.
Why treatment is usually recommended
Antibiotics reliably and quickly clear most UTIs and reduce the risk of complications. Because a straightforward course is short and effective, doctors generally recommend treating symptomatic UTIs rather than hoping they pass — especially if symptoms are more than very mild.
Treating promptly also gets you out of pain faster, which matters when the burning and urgency are miserable.
When you must not wait
Do not wait it out if you have fever, chills, back or flank pain, nausea or vomiting, blood in your urine, or if you're pregnant, have diabetes, or a weakened immune system — these need prompt medical treatment. In an emergency, call 000.
If you have UTI symptoms, the safest and fastest approach is to get assessed. A telehealth consult can determine whether you need antibiotics and, if so, send a script to your pharmacy quickly.
