Here are 11 warning signs of kidney failure that are essential to recognize, as they usually appear in late-stage CKD (Chronic Kidney Disease). Awareness can lead to immediate action and possibly reversing kidney damage naturally.

**1. Changes in Urination**
Kidney dysfunction affects urination with signs like increased nighttime urination, foamy urine, dark yellow or brown color, and blood in the urine.

**2. Fluid Retention**
Swelling in the legs, ankles, eyes, or face may occur as the kidneys struggle to remove excess fluid, leading to puffiness and fluid buildup around vital organs like the lungs and heart.

**3. Severe Itching and Greyish Skin**
Toxic waste buildup causes relentless itching, often worse at night, and skin may turn grey due to high phosphate levels.

**4. Fatigue and Shortness of Breath**
Fatigue is common due to a lack of red blood cells, while shortness of breath can result from fluid in the lungs or anemia caused by kidney failure.

**5. Dizziness and Brain Fog**
Anemia from kidney disease can cause dizziness, faintness, and difficulty concentrating.

**6. Metallic Taste & Ammonia Breath**
Uremia can lead to a metallic taste in the mouth and bad breath, often described as smelling like ammonia.

**7. Back or Kidney Pain**
Kidney damage can cause pain near the waist, often mistaken for back pain.

**8. Nausea & Loss of Appetite**
Waste buildup in the blood can lead to nausea, vomiting, and loss of appetite.

**9. Abnormal Electrolyte Levels**
Kidney failure causes imbalances in potassium, calcium, and phosphorus, which can increase the risk of heart problems.

**10. High Blood Pressure**
Kidneys struggling to remove fluid can lead to increased blood pressure, worsening kidney and heart health.

Recognizing these signs early allows for better management of kidney health.
