Factors responsible for causing diarrhoea after vagotomy are A/E:

D i.e. NoneEnterogastric ReflexWhen the chyme enters the intestine, the gastric muscle is inhibited and the motility stops leading to stoppage of gastric emptying - enterogastric reflex. This reflex involves the vagus nerve. Factors that stimulate enterogastric reflexDegree of distention of duodenumQAny degree of irritition of duodenal mucosaThe degree of acidity of duodenal chyme(2.The degree of osmolarity of chymeQPresence of breakdown products of protein and fat.* Chyme - Peristaltic movements of stomach mix the food bolus with gastric juice and conve it into semisolid material. Postvagotomy Diarrhoea,Tn.,' cal vagotomy is associated with climically significant diarrhoea in 5-10% of patient.Factors responsible for diarrhoea are:- Intestinal dysmotility (Irregular peristalsis)Q.- Rapid gastric emptyingQ.- Bile acid malabsorption- Bacterial over growth due to decreased gastric acid secretionQ.- Fat malabsorption- Exaggerated gastrointestinal peptide response.
