SecretinDiagnostic hormone peptide
Secretin is a digestive hormone that stimulates bicarbonate-rich pancreatic secretion. A synthetic preparation can make that response measurable during selected diagnostic procedures.
What is Secretin?
Secretin is a digestive hormone used in particular diagnostic assessments of pancreatic function and imaging. Its clinical role is more specific than the general idea of improving digestion. 1 2
How it works
Acid entering the duodenum prompts secretin signalling, which stimulates pancreatic bicarbonate secretion. Bicarbonate secretion is different from producing digestive enzymes. 1 2
Effects studied
What does the evidence show?
Diagnostic physiology and procedure-specific research
Neutralising acid is part of digestion
When acidic stomach contents enter the small intestine, secretin helps coordinate a response that includes bicarbonate secretion from the pancreas. This changes the environment in which digestive processes occur. The hormone is a signalling molecule, not a digestive enzyme itself.
Making a physiological response observable
A diagnostic preparation can be used to stimulate secretion under controlled conditions. Depending on the procedure, clinicians may assess pancreatic function or use the response to assist imaging or another specialised investigation. Each application has its own question and interpretation.
A result needs its clinical context
Reduced secretion can provide information about pancreatic function, but bloating or abdominal pain can have many causes. The stimulated response is one part of an assessment. Its usefulness depends on the protocol, accompanying measurements and reason for the test.
Why this is not a supplement profile
Secretin’s normal role in digestion does not establish that taking more improves everyday digestive symptoms. Diagnostic exposure also differs from repeated therapeutic use. Transient nausea or flushing and other product-specific risks need to be considered within the supervised procedure. Its role here is to produce a measurable response, not to serve as a routine digestive aid.
Safety & status
Nausea or flushing can occur. The relevant risks also include those of the accompanying diagnostic procedure. 2
Country and product status
Country-specific product availability and authorisation require a separate current check.
Frequently asked questions
Is it a treatment for routine bloating?
The evidence described here concerns diagnostic use, not a general bloating remedy.
