Kidney health: Facial changes that may indicate underlying issues

Certain facial changes may serve as indicators of underlying kidney issues, although facial appearance alone is insufficient for a medical diagnosis. Chronic kidney disease often progresses without obvious symptoms in its early stages.

Potential physical signs include skin pallor or a yellowish tint. This can occur because impaired kidney function may lead to decreased production of erythropoietin, a hormone that stimulates red blood cell production, potentially resulting in anemia.

Additionally, swelling around the eyes, particularly in the morning, can indicate fluid retention. This happens when kidneys struggle to regulate sodium and water levels or when protein, such as albumin, is lost through urine. In more advanced cases, swelling may also affect the face, legs, or ankles.
