What are gastrointestinal peptides?
They are hormones produced in the gastrointestinal tract that regulate various functions, including appetite and digestion.
True or False: Gastrointestinal peptides play a role in the regulation of body weight.
True
What is the main function of gastrointestinal peptides in relation to obesity?
Regulating hunger and satiety signals to control food intake.
Which gastrointestinal peptide is known as the ‘hunger hormone’?
Ghrelin
What is the role of ghrelin in obesity?
It stimulates appetite and promotes weight gain.
What is the main function of peptide YY (PYY) in relation to obesity?
Suppressing appetite and reducing food intake.
True or False: Cholecystokinin (CCK) is a gastrointestinal peptide that promotes satiety.
True
What is the role of leptin in obesity?
It regulates energy balance by inhibiting hunger and promoting energy expenditure.
Which gastrointestinal peptide is known to be involved in the regulation of glucose metabolism?
Glucagon-like peptide-1 (GLP-1)
True or False: Oxyntomodulin is a gastrointestinal peptide that promotes weight gain.
False
What is the relationship between gastrointestinal peptides and bariatric surgery?
Bariatric surgery can alter the levels of gastrointestinal peptides, leading to changes in appetite and weight loss.
Which gastrointestinal peptide is associated with the ‘satiety cascade’?
Peptide YY (PYY)
True or False: In obesity, there is typically an increase in ghrelin levels.
False
What is the main mechanism through which gastrointestinal peptides influence body weight?
By regulating appetite, food intake, and energy balance.
Which gastrointestinal peptide is secreted by the small intestine in response to food intake?
Cholecystokinin (CCK)
