What tests get run before someone starts a GLP-1 medication?

It varies a bit by provider, but common baseline checks include weight/BMI and waist circumference, blood pressure, and bloodwork covering blood sugar (A1C or fasting glucose), kidney function, and sometimes lipid panels and thyroid function. Providers also typically review personal and family medical history, particularly around pancreatitis and certain thyroid conditions, since these factor into whether a GLP-1 medication is appropriate. It's less about a single required test and more about building a general baseline picture before starting and for comparison at follow-ups.
