Concurrent Liver Disease

Updated June 18, 2026

Concurrent Liver Disease is defined as the simultaneous malfunction of the liver alongside Chronic Kidney Disease (CKD). Since the liver and kidneys act as the body's primary filtration systems, their combined failure creates a compounding crisis. In the CKD patient, the most immediate risk is Hepatic Lipidosis (Fatty Liver Disease). This life-threatening condition occurs when a cat stops eating due to the nausea of kidney failure (uremia). The body attempts to mobilize fat for energy, which overwhelms the liver and causes it to shut down. Additionally, older cats are prone to Cholangiohepatitis (inflammation of the liver and bile ducts). The presence of liver disease significantly complicates treatment because many medications are metabolized by the liver before being excreted by the kidneys. If both organs are compromised, drugs can accumulate to toxic levels in the bloodstream. Clinical signs such as vomiting, lethargy, and anorexia mimic CKD perfectly, but the presence of icterus (yellowing of the skin or eyes) specifically points to liver involvement. Diagnosis relies on blood panels showing elevated liver enzymes (ALT, ALP) alongside kidney markers.
