through the filtering system and enter the urine.
This may cause urine to appear unusually foamy.
Proteinuria can have several causes, ranging from temporary conditions to kidney disease.
A urine test can help determine whether excess protein is actually present.
Diabetes and Kidney Problems

Over time, high blood sugar can damage the small blood vessels and filtering structures inside the kidneys.
This can lead to protein leaking into the urine.
For this reason, persistent foamy urine can sometimes be associated with diabetic kidney disease.
