Research progress on the relationship between pancreatic exocrine insufficiency and intestinal microbiota in aging individuals / 中华肝胆外科杂志

ABSTRACT

Pancreatic exocrine insufficiency (PEI) refers to insufficient or non-synchronous secretion of trypsin caused by various reasons, resulting in dyspepsia and other symptoms. Intestinal microbiota is a large number of microbiota on the surface of intestinal mucosa. Its main functions include intestinal immune function, forming intestinal biological barrier and participating in the regulation of nutrition and metabolism. Due to aging, some elderly people often have unexplained chronic pancreatic insufficiency, which is often characterized by unexplained weight loss and malnutrition. Several studies have shown that the composition of intestinal microbiota changes significantly with age. This article focuses on aging and its related PEI and then reviews its possible effects on intestinal microbiota, in order to provide a reference basis for individualized prevention and treatment strategies according to the changes of pancreatic exocrine function and microbiota in the elderly.
