Common areas include:

• Feet
• Ankles
• Legs
• Hands
• Face

Fluid retention may worsen throughout the day or after long periods of standing.

4. Puffy Eyes

Persistent puffiness around the eyes may sometimes indicate protein leakage caused by kidney problems.

Healthy kidneys normally keep important proteins inside the bloodstream.

When kidney filters become damaged, protein may leak into urine instead.

This may contribute to:

• Puffy eyelids
• Swelling around the eyes
• Morning facial puffiness

5. Persistent Itching

Kidney dysfunction may lead to mineral imbalances and waste buildup that affect the skin.

Some individuals develop:

• Persistent itching
• Dry skin
• Irritated skin sensations

Severe itching may sometimes occur in advanced kidney disease.

6. Muscle Cramps

Electrolyte imbalances linked to kidney dysfunction may contribute to:

• Muscle cramps
• Twitching
• Tightness
• Leg cramps at night

The kidneys help regulate minerals such as:

• Potassium
• Calcium
• Sodium

Disruptions in these levels may affect muscle function.

7. Difficulty Concentrating

Waste buildup in the bloodstream may affect brain function and mental clarity.
