Exocrine pancreatic insufficiency, as the name implies, means that these digestive enzymes are not secreted and their absence makes them malabsorbed and undigested food causes bacterial overgrowth in the small intestine, which in turn affects the function of the intestine. The cause of the disease is usually secondary to diseases such as atrophy of the pancreatic alveoli and chronic pancreatitis, although it can also be genetically related. It is not age-related and the severity of the symptoms can vary from dog to dog (German Shepherds and Rough Collies are the most affected breeds).
