The stomach produces several hormones that play crucial roles in digestion and appetite regulation. These include:
Key Stomach Hormones:
- Ghrelin: This hormone signals your brain that your stomach is empty, triggering hunger and stimulating appetite. [Source: Cleveland Clinic]
- Gastrin: This hormone stimulates the production of gastric acid, aiding in protein digestion. [Source: NCBI PMC]
Other Relevant Gastrointestinal Hormones:
While not solely produced in the stomach, several other gastrointestinal hormones influence stomach function and are relevant to consider:
- Gastrin-releasing peptide (GRP): Plays a role in regulating gastric acid secretion and gut motility. [Source: NCBI PMC]
- Cholecystokinin (CCK): While primarily released in the small intestine, CCK influences gastric emptying and secretion. [Source: NCBI PMC]
- Secretin: Another hormone mainly released in the small intestine, it also affects gastric acid secretion, albeit indirectly. [Source: NCBI PMC]
- Somatostatin: This hormone inhibits the release of several gastrointestinal hormones, including gastrin, thereby regulating gastric acid secretion and other digestive functions. [Source: NCBI PMC]
Note: Enteroendocrine cells located throughout the gastrointestinal tract, including the stomach, secrete various hormones. This list highlights the most significant hormones related directly to the stomach's function. Other hormones such as incretins (GIP and GLP-1), and Peptide YY (PYY) from the gut significantly affect gastric emptying. [Source: NCBI PubMed]
