• Puffy ankles

  • Tightness in shoes

  • Visible swelling around the lower legs

Persistent swelling should be examined to determine the underlying cause.

5. Difficulty Concentrating

Kidney disease can affect oxygen delivery to the brain due to anemia or toxin buildup in the blood. As a result, some individuals may experience:

  • Difficulty focusing

  • Memory problems

  • Mental fog or confusion

These symptoms may develop gradually and may be mistaken for stress or fatigue.

6. Muscle Cramps

Electrolyte imbalances caused by impaired kidney function can trigger muscle cramps, particularly in the legs. Low levels of calcium or imbalances in sodium and potassium may contribute to these cramps.

Frequent or severe muscle cramps may indicate that the body’s mineral balance has been disrupted.

7. Poor Appetite

Waste buildup in the body can affect digestion and appetite. People with kidney problems may experience:

  • Reduced appetite

  • Unexplained weight loss

  • Nausea after eating

These symptoms may appear gradually and may worsen over time.

8. Puffiness Around the Eyes

Another sign that may appear early is swelling around the eyes, especially in the morning. This occurs when protein leaks into the urine due to impaired kidney filtration.

Visible puffiness or persistent swelling near the eyes may indicate kidney-related issues.

9. High Blood Pressure

The kidneys help regulate blood pressure by controlling fluid balance and releasing hormones that affect blood vessel function.

When kidney function declines, blood pressure may rise. At the same time, high blood pressure can also damage the kidneys, creating a harmful cycle.

Regular blood pressure monitoring is important for protecting kidney health.

10. Persistent Back Pain Near the Kidneys

Some people with kidney disease experience pain in the lower back or sides, near where the kidneys are located. This discomfort may feel like a dull ache or pressure.

However, not all kidney problems cause pain, which is why other symptoms should also be considered.

Protecting Kidney Health

Kidney disease often progresses quietly, but certain lifestyle habits may help protect kidney function.

Important steps include:

  • Drinking adequate water

  • Maintaining healthy blood pressure

  • Managing blood sugar levels

  • Eating a balanced diet

  • Avoiding excessive salt intake

  • Exercising regularly
