Nutrition and Acute Pancreatitis.

Acute pancreatitis (AP) is an acute inflammatory process of the pancreas that is characterized by severe abdominal pain, elevated pancreatic enzymes, and pancreatic changes on abdominal imaging. AP is, by nature, an inflammatory process that leads to protein catabolism and an increased metabolic rate, highlighting the strong need for early nutritional support in the initial management of the disease process. The goal of nutritional support in acute pancreatitis is to correct the negative nitrogen balance to reduce inflammation and improve outcomes. Many trials and multiple systemic reviews and meta-analyses have examined the best modality, timing, and composition of nutritional support for acute pancreatitis. Early enteral nutrition has emerged as an important aspect of the clinical management of AP. This narrative review aimed to provide an overview of the clinical management of nutrition in acute pancreatitis based on the currently available data.
