Silent Signs of Kidney Disease

3. Swelling (Edema)

Swelling in the legs, ankles, feet, hands, or face can indicate fluid retention due to impaired kidney function.

Why it happens:

• Damaged kidneys fail to remove excess fluid efficiently
• Sodium retention further contributes to edema

Practical example:

• Shoes or rings feeling tighter than usual
• Puffy eyes, especially in the morning

Action:
To identify the underlying cause and start treatment, speak with a healthcare provider.

4. High Blood Pressure

Kidneys help regulate blood pressure through fluid balance and hormone production. Dysfunction can lead to elevated blood pressure.

Signs to watch for:

• Persistent readings above 130/80 mmHg
• Headaches, dizziness, or blurred vision
• Blood pressure that is challenging to manage with medicine

Action:
Monitoring blood pressure and evaluating kidney function is essential, as hypertension can both result from and worsen kidney disease.

5. Unexplained Nausea and Vomiting

Accumulation of toxins in the blood (uremia) can cause digestive symptoms, including:

• Nausea
• Vomiting
• Loss of appetite
• Metallic taste in the mouth

Why it happens:
Toxins build up due to reduced filtration, irritating the gastrointestinal tract.

Action:
If persistent, these symptoms should be assessed alongside blood tests for kidney function.

6. Shortness of Breath

Kidney dysfunction can lead to fluid accumulation in the lungs or anemia, both causing breathlessness.

Signs:

• Difficulty breathing during mild activity
• Feeling winded even at rest in advanced stages
• Swelling in the legs or around the lungs

Action:
Prompt medical evaluation is needed, as fluid in the lungs can be life-threatening.
