Episode notes
Use PPIs For Reflux, Not Just Antacids
- Use proton pump inhibitors when reflux damages the esophagus and acid suppression is needed long‑term.
- Antacids only neutralize acid momentarily and don't prevent ongoing acid production.
H. pylori Causes Most Peptic Ulcers
- Helicobacter pylori causes many peptic ulcers by disrupting acid/bicarbonate balance and was proven experimentally.
- Treating H. pylori with antibiotics heals ulcers and earned a Nobel Prize for its discoverer.
CCK Coordinates Bile And Pancreatic Release
- CCK released from duodenum when fats arrive triggers gallbladder contraction and pancreatic enzyme release.
- Bile emulsifies fats into micelles so pancreatic lipases can digest them.
