Your urine can reveal kidney trouble. Signs include:
Foamy or bubbly urine (proteinuria, indicating kidney damage).
Blood in urine (hematuria, linked to infections or kidney stones).
Increased or decreased urination frequency.
A 2022 American Journal of Kidney Diseases study noted proteinuria in 30% of chronic kidney disease cases.
What to Do: Track urination patterns and consult a urologist if changes persist.
Urine Sign Possible Cause Action
Foamy Urine Proteinuria (kidney damage) Get a urine test
Blood in Urine Infection or stones See a doctor immediately
Frequent Urination Early kidney dysfunction Monitor and consult a nephrologist
4. Persistent Itching
Toxins that kidneys fail to filter can accumulate in the blood, causing severe itching, especially on the back or legs. A 2021 Clinical Nephrology study reported itching in 25% of advanced kidney disease patients.
What to Do: Moisturize skin, avoid scratching, and seek a doctor for blood tests.
5. Shortness of Breath
Fluid buildup in the lungs, linked to poor kidney function, can cause shortness of breath. Anemia from reduced erythropoietin also lowers oxygen delivery. A 2020 Chest journal study noted this symptom in 18% of kidney disease patients.
What to Do: Rest, avoid overexertion, and consult a doctor for lung and kidney evaluation.
6. High Blood Pressure
