Occasional bubbles in urine may be harmless, but persistent foamy urine is a cause for concern. It usually indicates protein leakage into the urine—a classic marker of kidney damage.
Protein should remain in the blood to support muscle, repair tissue, and maintain body functions. Losing it through urine is a sign your kidneys are struggling.
Frequent or Reduced Urination
Kidney disease can cause two opposite problems: urinating too frequently, especially at night, or urinating much less than normal.
Both conditions suggest that the kidneys are not regulating fluids properly. Frequent urination can also be linked to infections, while reduced output signals advanced kidney malfunction.
