title: Nutrition supplementation in patients with acute and chronic pancreatitis.
abstract: Acute pancreatitis is a hypermetabolic state characterized by increased protein catabolism, lipolysis, and glucose intolerance. Most patients presenting with acute pancreatitis are better within 5 to 7 days and can be resume a regular diet. Patients with severe pancreatitis and who are unable to eat within 7 to 10 days should receive nutritional support. The decision to use parenteral or enteral nutrition is controversial. More recent data suggest that jejunal feedings are just as beneficial, if not better, than parenteral nutrition. Marked weight loss and abdominal pain are the features of chronic pancreatitis. Steatorrhea develops when greater than 90% of pancreatic exocrine dysfunction occurs. Treatment focuses on pain control and pancreatic enzyme replacement. Pancreatic enzymes should be given with meals. Patients with refractory steatorrhea may benefit from the addition of an H2 antagonist or proton-pump inhibitor with pancreatic enzyme replacement. Micronutrients, including antioxidants, should be replaced if serum levels suggest a deficiency.
