Who qualifies for GLP-1 weight loss medication?
Qualifying is a medical decision, and it starts with a measurement most people already know. NIDDK (NIH) spells out where the BMI line sits.
The line, in the NIDDK's words
NIDDK (NIH) states: "Your health care professional may prescribe a medication to treat your overweight or obesity if you are an adult with a BMI of 30 or greater a BMI of 27 or greater, and you have weight-related health problems such as high blood pressure or type 2 diabetes". In plain terms, there are two routes. One is a BMI of 30 or greater. The other is a BMI of 27 or greater together with a weight-related health problem.
A number is not a prescription
The same page adds a limit: "Weight management medications aren’t for everyone with a high BMI." NIDDK (NIH) also explains what BMI does in the decision: "Health care professionals use BMI to help decide whether you might benefit from weight management medications."
The wording is "help decide", so BMI starts the conversation and does not end it. A provider who quotes you a price on the strength of your BMI alone has skipped the part where a health care professional decides whether you might benefit.
Where to read about obesity itself
Two overviews are worth your time before an appointment: the MedlinePlus page on obesity and the Cleveland Clinic page on weight control and obesity.
The question to ask
Ask who will decide whether you qualify and what they will review beyond your BMI, and treat "nobody, it is just a form" as a reason to keep looking.
