IntroductionBariatric procedures result in massive weight loss, however, not without side effects. How is homeostasis achieved in the digestive system? government site. The buffering effect is referring to the mucus that protects the duodenum from chime. Ingestion of food increases the intragastric pH as a result of the buffering effect, usually returning to baseline after 2h. We could verify the change in intragastric pH during meals, and in addition, we could demonstrate an increase in postpyloric pH, probably occurring due to increased buffering of ingested food passing into the duodenal bulb. The buffering effect of the 'duodenum' is the way mucus can neutralize the pH of the duodenum even after addition of the acidic chyme. The acidity of the gastric contents is therefore less than that of the pure gastric juice secreted bya pouch (KahnandYaure, 1924). We did not achieve full 24-h registrations in all patients, which could be regarded as a weakness, especially since four patients had to be excluded from the analysis regarding pH difference before and during meals. Explain in terms of the anatomy of the digestive system. The rise in gastric pH due to the buffering effect of the meal were less marked, however, and by contrast the brief spikes of duodenalacidification (falls in duodenalpHdownto and below pH 4) were more frequent, in patients with duodenal ulcer. Buffering refers to the neutralization of gastric acidity by the bicarbonate present in pancreatic juice. buffering effect in duodenum.
