The weight loss injection follow-up package is a set of laboratory tests designed for patients receiving injectable weight loss therapies (such as GLP-1 analogs like semaglutide, liraglutide, and others). This package aims to monitor the potential effects of these medications on thyroid function (due to warnings regarding medullary thyroid tumors), liver function, pancreatic function (to detect potential pancreatitis), and blood glucose control (especially for patients with diabetes or prediabetes).
