Kidney failure is a serious condition, but it doesn’t always mean the kidneys have completely stopped working. It can range from early kidney damage to advanced (end-stage) kidney disease.
What “kidneys are failing” usually means
Your kidneys are not filtering blood properly, so waste and fluid start building up in the body.
It can be:
- Acute kidney injury (AKI): sudden, sometimes reversible
- Chronic kidney disease (CKD): gradual, long-term damage
Common warning signs
- Swelling in feet, ankles, or face
- Very low or very high urine output
- Fatigue and weakness
- Nausea or vomiting
- Loss of appetite
- Itchy skin
- Shortness of breath
- Confusion in severe cases
Possible causes
- Diabetes
- High blood pressure
- Certain medicines (especially painkillers like NSAIDs if overused)
- Infections
- Dehydration or severe illness
- Kidney stones or blockage
What to do now (important)
If you suspect kidney failure, this needs medical evaluation urgently, especially if symptoms are present.
Doctors usually check:
- Blood tests (creatinine, urea)
- Urine tests
- Ultrasound of kidneys
Emergency warning signs (go immediately to hospital)
- No urine or almost no urine
- Severe swelling or breathlessness
- Chest pain or confusion
- Severe weakness or drowsiness
Treatment depends on cause
It may include:
- Medicines to control blood pressure or infection
- Stopping harmful drugs
- IV fluids (in dehydration cases)
- Dialysis in advanced cases
If you want, tell me:
- age
- symptoms
- any medicines being used
and I can help you understand how serious it might be and what to do next.
