A Quora user's concern about dark brown, coffee-like urine, fearing kidney or liver failure, prompted an expert explanation. A nephrologist clarified that while such urine color can indicate blood or waste pigments, it's not a definitive sign of organ shutdown. Symptoms of kidney dysfunction include swelling and fatigue, while liver issues may present with jaundice and pale stools. Medical evaluation and lab tests are necessary for accurate diagnosis, as urine color alone is insufficient.
