Foamy Urine: An Early Warning Sign of Kidney Damage
Your kidneys are like filters that clean your blood.
Sometimes, they get damaged and start leaking important stuff called proteins into your pee.
When this happens, your pee can get foamy, like when you whip egg whites.
This foam that lasts longer than usual can be a sign that something is wrong with your kidneys, possibly before you notice other problems.
Since it can be easy to miss and could indicate kidney damage, if you see it, tell a doctor.
Foamy urine can be an early sign of kidney damage.
Kidneys filter waste and fluids while retaining proteins.
Damaged kidneys can leak proteins, causing foamy urine.
Foamy urine appears when foam stays on the surface and may require several flushes to clear.
Detecting foamy urine early allows for timely intervention.
