The source article notes that excessive frothiness may indicate protein in the urine, and blood in urine can occur with kidney disease, kidney stones, infections, or other urinary problems.
Foamy urine once in a while can happen from a fast urine stream, but foam that does not go away, blood in urine, pain, fever, or cloudy urine should be checked.
3. Protein or Blood Found in a Urine Test
Sometimes kidney warning signs are found before you notice symptoms. A routine urine test may show protein, albumin, or blood cells in the urine.
Healthy kidneys usually keep important proteins in the blood. When the kidney filters are damaged, protein may leak into urine. The source article explains that albumin in urine can be an early sign of chronic kidney disease, and persistent protein in urine may indicate kidney damage.
This is why urine tests matter, especially for people with diabetes, high blood pressure, heart disease, or a family history of kidney disease.
