Question 1

What is the Meaning of Glucagon-Like Peptide-1 (GLP-1)?

Accepted Answer

Glucagon-Like Peptide-1, or GLP-1, is an incretin hormone synthesized and secreted by enteroendocrine L-cells primarily in the distal ileum and colon, and also by neurons in the brainstem. This peptide plays a crucial role in regulating glucose homeostasis following nutrient ingestion.

Question 2

What is the Context of Glucagon-Like Peptide-1 (GLP-1)?

Accepted Answer

GLP-1 functions as a crucial component of the gut-brain axis, playing a vital role in postprandial glucose homeostasis and appetite regulation. Its release is stimulated by nutrient ingestion, particularly carbohydrates and fats, signaling the presence of food in the gastrointestinal tract and initiating a coordinated metabolic response.

Question 3

What is the Significance of Glucagon-Like Peptide-1 (GLP-1)?

Accepted Answer

The clinical significance of GLP-1 stems from its broad physiological effects that contribute to metabolic health, particularly in managing type 2 diabetes mellitus and obesity. It helps normalize blood glucose levels, reduces cardiovascular risk factors, and supports weight management, thereby improving overall patient outcomes and mitigating disease progression.

Question 4

What is the Mechanism of Glucagon-Like Peptide-1 (GLP-1)?

Accepted Answer

GLP-1 exerts its effects by binding to specific GLP-1 receptors located on pancreatic beta cells, stimulating glucose-dependent insulin secretion. It simultaneously suppresses glucagon release from pancreatic alpha cells, slows gastric emptying, and promotes satiety through central nervous system pathways, collectively lowering postprandial glucose excursions and contributing to weight regulation.

Question 5

What is the Application of Glucagon-Like Peptide-1 (GLP-1)?

Accepted Answer

Clinically, synthetic GLP-1 receptor agonists are a cornerstone in the pharmacological management of type 2 diabetes and, increasingly, for chronic weight management. These medications are administered via injection or orally, mimicking and extending the physiological actions of endogenous GLP-1 to achieve sustained therapeutic benefits in glycemic control and body weight reduction.

Question 6

What is the Metric of Glucagon-Like Peptide-1 (GLP-1)?

Accepted Answer

Direct measurement of endogenous GLP-1 levels is not routinely performed in clinical practice for diagnosis or monitoring due to its rapid degradation by dipeptidyl peptidase-4 (DPP-4). Instead, the effectiveness of GLP-1-based therapies is assessed by monitoring clinical markers such as glycated hemoglobin (HbA1c), fasting and postprandial glucose levels, body weight changes, and improvements in associated metabolic parameters like lipid profiles and blood pressure.

Question 7

What is the Risk of Glucagon-Like Peptide-1 (GLP-1)?

Accepted Answer

Potential risks associated with GLP-1 receptor agonist therapy include gastrointestinal side effects such as nausea, vomiting, and diarrhea, which are typically transient and mild. Rare but serious adverse events, including pancreatitis and cholelithiasis, have been reported in some individuals. A contraindication exists for patients with a personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2 due to observations in rodent studies, though this specific risk has not been definitively confirmed in human populations.
