Acute Pancreatitis

Acute pancreatitis is inflammation of the pancreas that develops suddenly. The pancreas produces digestive enzymes and hormones; when it becomes inflamed, these enzymes can begin digesting the organ's own tissue, causing pain and disruption to digestion and metabolism. In dogs and cats, the condition can range from mild episodes to severe systemic illness. Owners often notice vomiting, loss of appetite, and a hunched or uncomfortable posture. In dogs, abdominal pain may be more obvious; cats can be quieter in their signs, sometimes showing only lethargy or withdrawal. The onset tends to be over hours to a couple of days, and the pattern can resemble several other digestive or metabolic conditions. This page explores the signals that may appear, the mechanisms that drive inflammation in the pancreas, how the condition is investigated through blood tests and imaging, and the range of supportive and medical approaches used to manage it. The course and response vary widely between individuals.
