This article from Hankyoreh delves into kidney health, specifically addressing the symptoms of proteinuria, which is characterized by foamy urine that doesn't dissipate quickly upon flushing. It explains that the kidneys serve as vital filters in the body, retaining necessary nutrients while expelling waste. However, when kidney function is compromised, essential proteins may leak into the urine, indicating significant health concerns and potential damage to the body's vascular system.

The article raises awareness about the indicators of proteinuria, such as foamy urine and swelling (edema) in the face and lower extremities, which can signal kidney dysfunction. It emphasizes that these symptoms can progress silently, leading to diminished bodily functions and other health complications like elevated blood pressure, especially when accompanied by continuous swelling. It calls for vigilance regarding these signs as they may point to underlying kidney diseases, including glomerulonephritis, which causes inflammation and damage to the kidney's filtration mechanisms.

Lastly, the text outlines the different causes of proteinuria and stresses the connection between it and systemic diseases like hypertension and diabetes, where gradual damage to the kidney's microvessels occurs. Furthermore, cardiovascular issues can also influence blood flow and pressure within the kidneys, exacerbating the risk of protein leakage. The article serves as a timely reminder during the Lunar New Year festivities to be mindful of dietary habits promoting kidney health.
