Secretin

What it's for

Secretin is a duodenal peptide hormone; synthetic human secretin is used diagnostically. Stimulates pancreatic bicarbonate secretion for diagnostic testing of exocrine function / imaging protocols.

What it does for the body

Stimulates pancreatic bicarbonate secretion for diagnostic testing of exocrine function / imaging protocols. People often hear about it through clinics, forums, or news — this guide sticks to what published research and regulators actually support.

What it targets

Secretin receptors (lock-and-key landing spots on cells) activation on pancreatic duct cells increases bicarbonate-rich fluid secretion. Researchers map these ideas in cells and animals first; human proof has to clear a higher bar.

Research context

Bottom line for readers: Secretin has a defined FDA-approved story. Use the citations tab to open labels and trial registries, and treat anything beyond the label as unverified.
