The odor comes from trimethylamine (TMA) excretion through sweat and urine
One of the target sites of GLP-1, and thus GLP1 receptor agonists, is the brain, where it acts to suppress appetite and promote satiety (or a feeling of fullness)

Furthermore, these pathways have also been linked to appetite regulation, modulation of gastric emptying, and cardiovascular effects ( Semaglutide and liraglutide effects on central nervous system regulation GLP-1 and GLP-1RA are involved in the activation of various central nervous system (CNS) processes, including satiety, thermogenesis, blood pressure, neurogenesis, and inflammation reduction ( Obesity has been associated with chronic inflammation, and GLP-1RA can modulate these inflammatory processes ( Moreover, GLP-1 promotes neurogenesis by reducing inflammation and decreasing the expression of proinflammatory cytokines IL-6, IL-10, and microglial activation ( Studies have observed that GLP-1RA decreases food intake, slows gastric emptying, and promotes the release of hormones such as leptin and peptide YY, involved in satiety ( Metabolic effects Semaglutide and liraglutide on insulin secretion The effect of GLP-1 and GLP-1RA in pancreatic -cells promotes glucose catabolism and insulin secretion ( Semaglutide, liraglutide and glucose homeostasis Liraglutide and semaglutide are mainly prescribed for the treatment of DM2 ( Lipid metabolism Semaglutide and Liraglutide effects on lipid metabolism GLP-1RA drugs have been associated with reduced food intake and body weight loss ( de novo lipogenesis

Tirzepatida, bajo el nombre de marca Mounjaro , ha sido autorizada para el tratamiento de la diabetes tipo 2 (DM2) en base a los resultados de cinco ensayos clnicos dnde se comparaba su capacidad para reducir la hemoglobina glicosilada (el indicador ms importante para medir los niveles de azcar en sangre) en pacientes diabticos frente a un placebo y frente a otros tratamientos activos como insulina o semaglutida (el principio activo de las famosas inyecciones Ozempic)
however, the study was not powered to demonstrate differences between subgroups
In RCTs comparing GLP-1RA and placebo, insulin doses were reduced before GLP-1RA initiation to avoid hypoglycemia, and close monitoring and insulin adjustments were done periodically
