Acute pancreatitis (AP) has varying severity, and moderately severe and severe AP has prolonged hospitalization and requires multiple interventions. These patients are at risk of malnutrition. There is no proven pharmacotherapy for AP, however, apart from fluid resuscitation, analgesics, and organ support, nutrition plays an important role in the management of AP. Oral or enteral nutrition (EN) is the preferred route of nutrition in AP, however, in a subset of patients, parenteral nutrition is required. EN has various physiological benefits and decreases the risk of infection, intervention, and mortality. There is no proven role of probiotics, glutamine supplementation, antioxidants, and pancreatic enzyme replacement therapy in patients with AP.
Core Tip: Nutrition improves the outcomes of acute pancreatitis (AP). In mild AP, solid food can be given when the patient is pain-free and hungry. In moderately severe and severe pancreatitis, feeding can begin as early as possible if there are no contraindications for an oral diet. If the patient does not tolerate an oral diet, tube feeding can be tried; and in case of gastric outlet obstruction or gastroparesis, nasojejunal tube feeding is preferred. Parenteral nutrition should be provided in case of complete intolerance or contraindications to oral/enteric feed or supplemented along with enteral feed if energy targets are not met.
