What foam in urine can indicate, and when should you consult a healthcare professional?

Many people have noticed foam in their urine at some point and dismissed it without much concern. It’s often thought to be normal, a result of urinating forcefully, dehydration, or simply “something that always happens.” However, when this foam is abundant, persistent, and appears repeatedly, it may be sending a silent warning about your kidney health.

Excessive foam in urine is not a minor issue. In medicine, it’s often the visible manifestation of a problem that isn’t immediately apparent: protein loss through the kidneys.
