Changes in Urination

Look out for foam, blood, or frequent nighttime urination. Your kidneys filter waste through urine—so any sudden change could be an early indicator of kidney trouble.

Swelling in Legs or Ankles

Fluid retention in lower limbs can signal poor kidney function. When kidneys can’t remove excess fluid, it builds up—causing puffiness or swelling, especially in the feet and ankles.

Constant Fatigue

Feeling unusually tired? It could be more than just stress. Damaged kidneys can cause a drop in red blood cell production, leading to anemia and constant tiredness.

Persistent Itching or Dry Skin

Waste buildup in your blood can affect your skin. If your skin feels itchy, flaky, or dry—especially without any skin condition—it may be due to kidney-related toxins.

Shortness of Breath

Trouble breathing during rest or light activity? This could be caused by fluid in your lungs due to kidney failure or anemia from reduced red blood cells.
