Signs of Kidney Disease in the Feet

Kidney disease is often referred to as a “silent” condition because many people do not notice symptoms until the disease has already progressed. However, one of the most visible warning signs can actually appear in the feet. Paying attention to these early signals may help in detecting kidney problems before they become severe.

1. Swelling (Edema)

When the kidneys are not functioning properly, they are unable to remove excess fluid and sodium from the body. This leads to fluid retention, often noticeable in the feet and ankles. Swelling may become more pronounced at the end of the day or after long periods of standing.

2. Discoloration of the Toenails

Kidney dysfunction can cause changes in nail color, such as a purplish or bluish tint, which indicates poor circulation or oxygenation. Brittle or unusually shaped nails may also be a subtle sign of underlying kidney disease.

3. Foot Pain or Redness

Painful inflammation, redness, or sensitivity in the toes or feet may be linked to uric acid buildup, a common complication of chronic kidney disease. High uric acid levels can lead to gout, which frequently affects the feet.

4. Cold Feet
