A new study indicates that many patients with chronic kidney disease (CKD) have some degree of smell loss, and that impairments in patients’ ability to smell are linked with worse nutritional status. The findings, which appear in an upcoming issue of the Journal of the American Society of Nephrology (JASN), are significant because malnutrition is a well-known complication of CKD, and it can contribute to poor quality of life, poor overall health, and even premature death.
