9 Signs of Kidney Failure
Kidney failure means the kidneys are no longer able to filter waste, balance fluids, and regulate important body chemicals properly. Symptoms may develop gradually in chronic kidney disease or appear quickly in acute kidney injury.
π£ 1. Fatigue and Weakness
β Waste buildup and anemia can cause persistent tiredness
β Everyday activities may become more difficult
π£ 2. Swollen Feet, Ankles, or Legs
β Damaged kidneys may retain extra salt and fluid
β This can cause swelling, especially in the lower legs and ankles
π£ 3. Puffiness Around the Eyes or Face
β Fluid retention can cause facial or eyelid swelling
β This may be more noticeable in the morning
π£ 4. Shortness of Breath
β Extra fluid can sometimes build up in or around the lungs
β Anemia may also contribute to breathlessness
π£ 5. Reduced Urination or Urine Changes
β Urine output may decrease in some cases
β Urine may become foamy, dark, bloody, or otherwise unusual
β Some people with kidney failure may still pass a near-normal amount of urine
π£ 6. Nausea or Vomiting
β Waste products accumulating in the blood can upset the stomach
β Persistent nausea may become more common as kidney function worsens
π£ 7. Loss of Appetite
β Food may become less appealing
β Changes in taste, nausea, or waste buildup can reduce appetite
π£ 8. Itchy Skin
β Advanced kidney disease can cause persistent generalized itching
β Abnormal mineral balance and retained waste products may contribute
π£ 9. Confusion or Drowsiness
β Severe buildup of toxins and electrolyte disturbances can affect the brain
β Confusion, poor concentration, extreme drowsiness, or seizures can occur in advanced cases
π£ Diagnosis & Management
β Blood tests such as creatinine and eGFR assess kidney function
β Urine tests help detect protein, blood, or other abnormalities
β Treatment depends on the cause and may include controlling blood pressure, diabetes, fluid balance, and electrolyte problems
β Advanced kidney failure may require dialysis or kidney transplantation
π£ Seek Urgent Medical Help If
β Urine output suddenly becomes very low or stops
β Severe breathlessness or rapidly increasing swelling develops
β Persistent vomiting, confusion, or extreme drowsiness occurs
β Chest pain, seizures, or severe weakness develops
