Is Under-Eye Swelling a Sign of Kidney Problems? Doctors Warn

Swelling under the eyes may not always be caused by fatigue or lack of sleep; it can also be linked to kidney function. The kidneys are vital organs responsible for filtering the blood and removing waste products and excess fluids from the body. When the filters inside the kidneys are damaged, essential proteins such as albumin may leak into the urine. As protein levels in the blood decrease, blood vessels lose their ability to retain fluid properly. As a result, fluid leaks into the soft tissues beneath the eyes, leading to puffiness or swelling. Since the body remains in one position during sleep, this swelling may appear more noticeable in the morning.

If such symptoms occur frequently, doctors usually recommend two important tests to assess kidney health. A urine test can help detect protein leakage, while a creatinine blood test indicates how efficiently the kidneys are filtering the blood. Identifying the problem at an early stage can help prevent serious complications such as swelling in the legs and feet. People with diabetes or high blood pressure should be especially cautious, as they are at greater risk of kidney-related issues. Keeping blood sugar and blood pressure under control, reducing salt intake, and limiting sugary foods can support kidney health. It is important not to ignore even minor physical changes and to seek medical advice promptly.
