Hi Aunt Vadge,
Back in August I had sex with my now-ex for the first time and got a UTI straight away because we weren’t careful. It took a while, but lots of water and no sex cleared it. A few weeks later I felt like I had a UTI again, but milder, and a glass of water would make it go away straight off.
Now every time I don’t drink enough water in a day I feel like I have a UTI, and I don’t understand why it keeps happening. I haven’t had sex or any sexual contact since August.
Yours,

Hi there Uncomfortable,
What you’re describing makes good sense once you know how it works: your urine stream is one of the main things that keeps your urethra flushed and comfortable, so when you don’t drink enough, your urine gets concentrated and acidic, and that strong, scant urine irritates an already-sensitive urethra – giving you that ‘UTI feeling’ that vanishes the moment you drink a glass of water and dilute things again.
That on-off, water-fixes-it pattern is the signature of urethral irritation rather than a true infection (a real UTI doesn’t clear up with a single glass of water), and it often lingers for a while after an actual UTI, like the one you had in August, has left the lining a bit raw and over-reactive.
So the simple fix is to stay well and steadily hydrated – sip water across the whole day rather than letting yourself get dry – and the feeling should keep settling as the urethra calms down.
A few extra things help: go easy on bladder irritants (caffeine, alcohol, very acidic or spicy foods), wee fully and don’t hold on, and if you want to support the lining, D-mannose or high-dose cranberry are gentle options.
The one time to actually get tested is if it stops responding to water and tips into a real UTI – constant burning, a frequent urge with little coming out, cloudy or smelly urine, or any lower-back pain or fever – in which case see a doctor.
But from what you’ve described, this is an oversensitive urethra that just needs consistent hydration and a bit of time, not an infection.
Warmest regards,
Aunt Vadge
