GLP-1 delays the passage of food from stomach to small intestine, which flattens the post-meal rise in glucose and prolongs the sensation of fullness. The effect is well documented for GLP-1 receptor agonists and is thought to diminish somewhat with continued exposure.
Slower emptying is also the most plausible mechanism for nausea early in treatment, which is why gastrointestinal events in the trials were concentrated during escalation.
GLP-1 receptors are present in the area postrema and nucleus of the solitary tract in the brainstem, and in hypothalamic regions governing appetite. Agonism there reduces food intake in animals and people. Whether circulating peptide reaches these sites directly or signals through peripheral nerves is an active question in the literature.
For a peptide of retatrutide's size with albumin binding, how much of the central effect is direct is not settled, and the phase 2 trials did not address it.
Nausea, vomiting, diarrhoea and constipation were the most common events in both phase 2 trials, were dose-related and mostly mild to moderate. That pattern is what the mechanism predicts and what the wider class shows.
It is a description of what was observed in those trials, not a statement about any individual.
