A doctor in Taiwan is warning that a common cold can sometimes indicate underlying kidney problems. Beyond respiratory symptoms, five key signs of kidney inflammation should be monitored. These include changes in urine color – specifically, urine appearing cola-colored – which should not be ignored. Other warning signs involve swelling in the face and ankles, changes in urination frequency, and persistent fatigue. Medical professionals in Taiwan emphasize the importance of seeking prompt evaluation if these symptoms accompany a cold, as early detection is crucial for effective treatment and preventing potential kidney damage. Ignoring these signals could lead to more serious health complications.
