Monitoring parameters typically assessed in trials include: Body weight and BMI measured at each visit to track progress Blood glucose and HbA1c particularly important for participants with type 2 diabetes or non-diabetic hyperglycaemia (sometimes called prediabetes) Lipid profile including total cholesterol, LDL, HDL, and triglycerides Liver function tests given the metabolic effects of glucagon receptor activation Renal function especially relevant if gastrointestinal side effects lead to reduced fluid intake Blood pressure and heart rate cardiovascular parameters are routinely assessed Calcitonin levels some trial protocols include calcitonin measurement given the theoretical thyroid C-cell risk associated with GLP-1 receptor agonists, based on rodent data
