Wasting continuum disorders such as cachexia are highly prevalent in cardiorenal syndrome, yet the clinical impact, pathophysiological mechanisms, and management options have not been well elucidated in previous literature. In this review, we aim to summarize current knowledge regarding the epidemiology, clinical impact, and pathophysiology of CRS-induced wasting continuum disorders, as well as highlight effective and potentially emerging treatment options.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Recent Findings<\/jats:title>\n                    <jats:p>Neurohormonal activation, inflammation, metabolic dysfunction, gastrointestinal abnormalities, protein degradation, and mitochondrial pathway dysfunction are pathophysiologic mechanisms underlying CRS-induced cachexia.
