Weight and metabolism: medical weight care
Medical weight care starts with your history, a physical evaluation where required, and lab work, then a licensed provider decides whether a prescription medicine is appropriate. GLP-1 medications are prescription drugs with real side effects and a boxed warning about thyroid C-cell tumors, so they are not right for everyone. The guides in this topic explain how these medicines work, what their labels say, how they compare, and what questions to ask about cost and follow-up. They describe evidence and label information; they are not a prediction of how anyone's weight will change.

Prescription treatment requires an evaluation by a licensed healthcare provider, who decides whether treatment is appropriate for you. Not everyone qualifies. Completing an assessment, booking a visit, or paying a fee does not guarantee a prescription.
