Kidney disease is often hidden but quite pervasive. According to 2019 data from the U.S. Centers for Disease Control and Prevention, more than one in seven Americans—37 million adults—have some chronic form of the condition. This means these vital organs aren’t filtering toxins and waste out of the blood as well as they should, but they haven’t completely failed. Although simple blood tests can identify kidney deficiencies, explains Fahad Aziz, a nephrologist at the University of Wisconsin-Madison, these cases rarely develop symptoms.
