The gastrointestinal hormones can be divided into three main groups based upon their chemical structure.

• Gastrin-cholecystokinin family: gastrin and cholecystokinin
• Secretin family: secretin, glucagon, vasoactive intestinal peptide and gastric inhibitory peptide
• Peptide family: somatostatin, motilin and substance P.

There is some disagreement over what is considered a gastrointestinal hormone. For example, MeSH doesn't include somatostatin or substance P in that category, though it does include them in several other categories.^[1]
