Telling normal ageing apart from disease that needs urgent care
Quick answer
Filtration naturally falls roughly 0.5 to 1 unit a year after age 40. Protein leakage or a faster drop signals disease that needs treatment. Older adults considering stem cell infusion for kidney disease need careful assessment of cardiac risk, frailty and drug interactions first.
Polypharmacy is the common trap: painkillers, herbal products and high-dose vitamins, several of which are nephrotoxic or distort test results. A pharmacist-led medication review often protects the kidney immediately and for free.
Dehydration is another cause of sudden renal deterioration in older people, since thirst perception declines with age. Following fluid advice, especially in hot weather or during diarrhoea, matters more than most realise.
If considering cell therapy, ask about fluid load during infusion, reaction risk and the reality of repeated trips to Korea. For frail older adults, resources may do more good in muscle rehabilitation and nutrition.
Yes, when the aim is quality of life and avoiding dialysis within remaining life expectancy — set goals with doctor and family.
Sustained high doses raise oxalate stone risk and renal load; use only as needed and ask your doctor.
It depends on fitness; travel with a companion and plan rest between appointments.
Those with diabetes or hypertension should test at least yearly, or more often as advised.
Indirectly, through blood pressure, glucose and muscle mass — all linked to renal decline.
