Pancreatitis: Pancreatitis is inflammation of the pancreas, an organ in the abdomen that lies along the border of the stomach and upper intestine. The pancreas produces enzymes to aid in the digestion of fats and starches. It is also the gland that produces insulin, which is necessary to help us use blood sugar properly (see "Diabetes Mellitus"). Pancreatitis in dogs is often associated with the feeding of fatty table foods (scraps); this is not so often true for cats, although many cats will be overweight. The symptoms of pancreatitis in dogs include acute vomiting, appetite loss, abdominal pain, and dehydration; cats often have a much more subtle presentation, often only appetite loss. Diagnosis is by blood test, x-ray, and ultrasound. Often, the only way to make a definitive diagnosis in cats is by biopsy. Treatment requires hospitalization, IV fluids, supportive care, the withdrawal of food, and pain management. Serious cases are life threatening and may require surgery, feeding tubes, and a high level of intensive care. Pancreatitis has a tendency to recur and is best managed long term with a special diet.
