Foamy urine: the kidney warning sign most people ignore

The next step for anyone who notices persistent foam in their urine is straightforward: raise it with a healthcare provider and request a basic urine test. For those already managing diabetes or high blood pressure, the open question is whether kidney screening is already part of their regular follow-up — if not, it should be. Researchers and clinicians continue to study how early intervention in proteinuria can slow or halt the progression toward chronic kidney disease, a condition that affects hundreds of millions of people worldwide and for which treatment becomes significantly more complex once significant damage has occurred.
