The question "do I qualify?" usually starts small: a clothing size that keeps changing, a slow climb over several years, or a symptom that makes you wonder if something deeper is going on. Thresholds and rules come from each medicine's labeling and your prescriber, so what helps most is knowing what to gather and what to ask, so a clinician can answer the question for you.
Qualifying is a clinician's decision
Ask the prescriber how the medicine's approved labeling and your health history bear on whether it fits you. Treat anything online that gives you a quick yes or no with caution.
Start with the smallest sign
Think about what first made you ask. Write down when you first noticed the change, what else shifted around the same time, and whether any symptoms came with it. For a general reference on adult weight and health, see NIDDK's explanation of adult overweight and obesity.
Your history, gathered before the visit

- Bring your weight and measurements over time, as far back as you can reliably recall.
- Bring a list of every medicine and supplement you take now.
- Write out your health conditions and family history, as you know them.
- Note what you have already tried for weight, and what happened.
- Mention any plans that might matter to a prescriber, such as pregnancy plans.
Questions that help settle eligibility
- What measurements or tests do you use to decide if medication fits me?
- Which medicines are approved for what I am describing, and for whom?
- What would make medication a poor fit for me?
- What non-medication steps do you want in place alongside it?
Where to read the official material
Public agencies publish descriptions of these medicines. The one to open first is NIDDK's page on prescription medications for overweight and obesity. Approvals are also announced publicly, for example in the FDA's announcement of a new medication for chronic weight management.
Leave the qualifying call to a prescriber
Do not decide on your own that you do or do not qualify. Collect your history, track the small signs, and ask a licensed prescriber the questions above. Habits matter in any plan, and NIDDK's guide to healthy eating and physical activity for life is a useful companion read before the appointment.
Public agency material is the source of these questions, and it cannot tell you whether you qualify.
