Glucagon-like peptide 1 (GLP-1) based drugs effectively manage type 2 diabetes and impact gastrointestinal functions. Understanding these GI effects is crucial for recognizing side effects and exploring new therapeutic uses.
Area of Science:
- Endocrinology
- Gastroenterology
- Pharmacology
Background:
- Glucagon-like peptide 1 (GLP-1) is a gut hormone regulating blood glucose by stimulating insulin and inhibiting glucagon.
- GLP-1 based therapies, including GLP-1 receptor agonists and DPP-4 inhibitors, are widely used for type 2 diabetes.
- These drugs offer benefits beyond glucose control, such as weight management and improved cardiovascular risk factors.
Purpose of the Study:
- To review the gastrointestinal (GI) actions of endogenous GLP-1 and GLP-1 based therapies.
- To highlight the clinical relevance of understanding GLP-1's GI effects for managing side effects and potential GI disease treatment.
Main Methods:
- Literature review of studies on GLP-1 and its therapeutic analogues.
- Analysis of the impact of GLP-1 on gastric emptying, intestinal motility, and exocrine function.
Main Results:
- Endogenous GLP-1 and its derived drugs significantly slow digestion by influencing the stomach, intestines, exocrine pancreas, gallbladder, and liver.
- Common GI side effects associated with these therapies necessitate clinical recognition.
- GLP-1's enterogastrone functions suggest potential applications in treating GI disorders.
Conclusions:
- GLP-1 based therapies exert substantial effects on the GI system, impacting digestion and related organs.
- Awareness of these GI actions is essential for safe and effective patient management in diabetes care.
- Further research into GLP-1's GI roles may uncover novel therapeutic strategies for gastrointestinal diseases.
