Exocrine Pancreatic Insufficiency (EPI) is defined as a syndrome caused by the failure of the pancreas to secrete adequate digestive enzymes. Under normal conditions, the pancreas releases enzymes (lipase, amylase, and protease) into the small intestine to break down fat, starch, and protein. In cats with EPI, this function is lost, typically due to the end-stage destruction of pancreatic tissue from Chronic Pancreatitis. This results in a state of starvation despite adequate food intake. The classic clinical presentation involves polyphagia (a ravenous appetite) accompanied by profound weight loss and voluminous, loose, pale stools that may appear greasy (steatorrhea). For the Chronic Kidney Disease (CKD) patient, this is a dangerous comorbidity because it dramatically accelerates muscle wasting (cachexia), which is already a primary concern in renal management. Diagnosis is definitively confirmed via the feline Trypsin-Like Immunoreactivity (fTLI) blood test, which will show abnormally low levels of digestive enzymes. Treatment requires the lifelong addition of powdered pancreatic enzyme replacements to every meal to allow the cat to absorb nutrients.
