Well, most of us – adults that is, have been drinking for many years, and, if you have made it into your 50’s, 60’s or older and are in reasonable health, you are probably close to the sweet spot.
When I say negative, I mean urine that has been analysed and found to be normal; just the right level of sugar, protein or salt; not too much or too little. Goldilocks pee.
In most instances it is straightforward, and here is the trick.
Stop, look and listen.
When in doubt, don’t UTI.
It is likely that a doctor, a nurse or carer admitting, ‘something is wrong, I don’t know what,’ is better than heading off down a therapeutic blind alley.
