肠道消化吸收所必需的蛋白酶、脂肪酶和淀粉酶来自胰腺,胰腺分泌的胰岛素和高血糖素亦为机体代谢所必需,因此胰腺是维持机体正常营养代谢的重要器官。急性胰腺炎时外分泌功能可以发生不同程度的障碍,慢性胰腺炎则可以导致外分泌和内分泌功能均呈进行性下降,急性和慢性胰腺炎患者都可以因为疼痛和吸收不良而不能耐受饮食,因此营养不良是胰腺炎常见的并发症,胰腺炎营养治疗的研究也越来越得到人们广泛的重视。病理生理基础胰腺外分泌受神经反射、胃肠液 pH 值、脂肪、蛋白质等多种因素的作用而调节。迷走神经传出纤维 Proteases, lipases and amylases necessary for intestinal digestion and absorption are derived from the pancreas. Insulin and glucagon secreted by the pancreas are also essential for the metabolism of the body. Therefore, the pancreas is an important organ that maintains the body’s normal nutritional metabolism. Exocrine function in acute pancreatitis can occur in varying degrees of obstacles, chronic pancreatitis can lead to exocrine and endocrine functions were progressive decline in patients with acute and chronic pancreatitis can be because of pain and malabsorption can not tolerate the diet, nutrition Poor is a common complication of pancreatitis, pancreatic nutritional therapy research has also been more and more people’s attention. Pathophysiology Pancreatic exocrine by nerve reflex, gastrointestinal fluid pH, fat, protein and other factors and regulation. Vagal nerve fibers
