Kidney failure, also called renal failure, occurs when the kidneys lose their ability to filter waste and excess fluids from the blood. Ignoring early signs can lead to irreversible damage requiring lifelong dialysis or even kidney transplantation. Here’s a detailed guide on 8 warning signs of kidney failure and what to do:
1. Swelling (Edema)
-
What happens: Kidneys failing to remove excess fluid leads to swelling in the legs, ankles, feet, and sometimes around the eyes.
-
Direction: Elevate legs when sitting, reduce salt intake, and consult a doctor promptly. Persistent swelling needs urgent testing of kidney function (blood urea, creatinine).
2. Fatigue and Weakness
-
What happens: Accumulation of toxins in the blood (uremia) causes constant tiredness, low energy, and difficulty concentrating.
-
Direction: Don’t ignore fatigue. A simple blood test (eGFR) can detect kidney function decline early.
3. Changes in Urination
-
Signs:
-
Less urine output or very frequent urination
-
Urine that is foamy, bubbly, or dark-colored
-
Blood in urine
-
-
Direction: Track urine changes and report immediately. Early detection allows interventions to slow damage.
