Weight loss in the first week on GLP-1 therapy like semaglutide or tirzepatide is typically minimal to nonexistent for most patients
Although a decrease in systolic blood pressure is observed with GLP-1 RAs (ranging from 1.84 mmHg [95% CI 3.48 to 0.20] to 4.60 mmHg [95% CI 7.18 to 2.03]) [113], the possibility of requiring adjustment of simultaneous diuretic treatment should be considered

Activating these receptors may lead to an apparent increase in growth hormone synthesis, and some researchers suggest that the simultaneous activation of the GHRH and ghrelin receptors on these pituitary cells may result in synergistically increased growth hormone elevation
The findings indicate that GLP-1 agonists may be an effective therapy to avoid severe liver disease in those with concurrent type 2 diabetes, according to the study authors
