Treatment of constipation in pancreatitis is as follows: 1. In mild cases of pancreatitis constipation, oral laxative drugs can be taken as appropriate to help defecation, such as oral lactulose and other drugs; 2. Patients with severe pancreatitis need to pay attention to the maintenance of intestinal function and can choose to induce diarrhea, oral antibiotics help to reduce the displacement of bacteria when the intestinal barrier function is impaired, and can reduce the inflammatory response of the intestine. Catheterization can reduce bacterial overgrowth in the intestinal lumen and also promote intestinal peristalsis and maintain the intestinal mucosal barrier, or you can choose enemas for laxatives. Enema solution can be added with herbs to exert effect. Mannitol mixed with boiled water can also induce diarrhea when taken orally, and lactulose can be added after the stool is discharged.
