Your mum's routine urine test comes back "dirty" with bacteria. The doctor prescribes antibiotics. Problem solved, right?
Actually... if she feels completely fine, that prescription could be a medical disaster. 🛑
As we age, our plumbing changes. Up to 1 in 5 older adults walk around every single day with bacteria in their urine, but have zero pain or burning. We call this Asymptomatic Bacteriuria.
Think of your parent's bladder like a house. Right now, it’s occupied by harmless, peaceful "squatters" (good bacteria). They take up space so dangerous germs can't move in. When you give unnecessary antibiotics, you evict the peaceful squatters. What moves in next? Dangerous superbugs that can cause severe, infectious diarrhoea.
"But Dr. Lim, her urine smells bad!"
Smell alone does not equal an infection. Dehydration, diet, or daily meds can make urine smell strong.
How to spot a REAL infection in seniors (especially those with dementia):
Look for atypical signs. Sudden confusion, unexplained falls, extreme weakness, or a sudden spike in blood sugar. That is when we treat!
The Golden Rule: We treat the PATIENT, not the lab report.
