What it is

A 29-amino-acid pancreatic hormone that raises blood glucose; used as a rescue medicine for severe low blood sugar and as a diagnostic aid.

Type: Peptide hormone.

Definition (National Library of Medicine)

“A 29-amino acid pancreatic peptide derived from proglucagon which is also the precursor of intestinal glucagon-like peptides. Glucagon is secreted by pancreatic alpha cells and plays an important role in regulation of blood glucose concentration, ketone metabolism, and several other biochemical and physiological processes.”

  • MeSH: Glucagon

Human research

The registered human trials and peer-reviewed human studies linked below are listed from ClinicalTrials.gov and PubMed. A study is linked only when Glucagon is one of its interventions, or is named in the study title or subject headings.

Listing a study does not mean it showed a benefit, and it is not medical advice.
