To get a GLP-1 prescription for weight management you generally need a BMI of 30 or higher, or 27 or higher with a weight-related condition such as type 2 diabetes or high blood pressure. A licensed provider, in person or by telehealth, confirms you meet the criteria and rules out contraindications before writing the prescription.
GLP-1 receptor agonists like Wegovy, Zepbound, and Ozempic are prescription-only drugs in the United States. That means a clinician has to evaluate you and decide the medication is appropriate. Below is what doctors actually look for, how to prepare, and how insurance fits in.
What criteria do doctors actually use to prescribe a GLP-1?
Most prescribers follow the FDA-approved labeling for chronic weight management, which is built around body mass index (BMI) plus weight-related health conditions. A licensed clinician can write the prescription once you meet these thresholds, independent of whether your insurance later agrees to pay.
BMI thresholds
The two main cutoffs come straight from the drug labels. A BMI of 30 or higher qualifies on its own. A BMI between 27 and 29.9 qualifies if you also have at least one weight-related condition.
Qualifying comorbidities
Recognized weight-related conditions in the FDA labeling include hypertension (high blood pressure), type 2 diabetes, dyslipidemia (high cholesterol), obstructive sleep apnea, established cardiovascular disease, and metabolic dysfunction-associated steatohepatitis (MASH). Even one of these at a BMI of 27 or above is usually enough to meet the prescribing standard.
When a diabetes diagnosis changes the path
If you have type 2 diabetes, drugs like Ozempic and Mounjaro are labeled for blood-sugar control rather than weight loss, and the prescribing logic shifts to your A1C and overall diabetes management. That can make access and insurance coverage easier, because the medication is being used on-label for diabetes.
| Eligibility factor | Standard threshold | Notes |
|---|---|---|
| BMI alone | 30 or higher | Qualifies without a comorbidity |
| BMI with a condition | 27 to 29.9 | Needs one weight-related comorbidity |
| Qualifying conditions | Hypertension, type 2 diabetes, high cholesterol, sleep apnea, heart disease, MASH | One is typically enough |
| Minimum age | 12 for Wegovy and Saxenda; 18 for Zepbound, oral Wegovy, and Foundayo | Varies by product |
| Diabetes route | A1C-based | Ozempic and Mounjaro are labeled for type 2 diabetes |
These figures reflect FDA labeling as of 2026; confirm current criteria with your prescriber, since labels are periodically updated.
What will a doctor ask before prescribing?
A prescriber is trying to confirm two things: that you genuinely qualify, and that the drug is safe for you specifically. Expect a focused conversation rather than a quick rubber stamp.
Your weight and medical history
You will usually be asked your current height and weight (to calculate BMI), your weight history, previous diet and exercise attempts, and any past use of weight-loss medication. Honest answers matter, because they shape both the prescription and any future insurance request.
Red flags and contraindications
GLP-1 drugs carry a boxed warning related to a personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2. Providers also ask about pancreatitis, gallbladder disease, severe gastrointestinal conditions, and pregnancy or plans to become pregnant, since these can rule the medication out or change the plan.
Labs your provider may order
Many clinicians check baseline labs such as A1C, a metabolic panel, and sometimes thyroid or lipid testing. These help confirm a comorbidity, establish a baseline, and catch anything that would make treatment unsafe.
Should you use telehealth or see an in-person doctor?
Both routes can produce a legitimate prescription. The right choice depends on your medical complexity and what you want from ongoing care.
When telehealth makes sense
Telehealth platforms are fast, convenient, and often cheaper for the visit itself. They work well if you are relatively healthy, know your numbers, and want a streamlined process. We cover the legitimate online routes in our guides to getting semaglutide prescribed online and the broader ways to get a GLP-1 online.
When in-person is better
If you have complex medical history, take many medications, or want hands-on monitoring and coordination with your other doctors, an in-person primary care or obesity-medicine clinician is usually the stronger option. They can examine you, order labs in-house, and manage side effects over time.
How does insurance and prior authorization work?
Meeting the prescribing criteria is separate from getting insurance to pay. Coverage for weight-loss GLP-1s is inconsistent, and many plans add their own hurdles on top of the FDA label.
Why prior authorization exists
Prior authorization is the insurer's way of confirming you meet their coverage rules before they pay. Plans commonly require a documented BMI, evidence of a qualifying condition, and sometimes a record of a supervised lifestyle attempt or a prior trial of another medication.
What documentation strengthens approval
A clear paper trail helps: documented BMI over time, diagnosis codes for any comorbidity, and notes on prior diet, exercise, or medication attempts. The more your chart matches the plan's checklist, the smoother the approval. Our GLP-1 insurance coverage guide breaks down what plans typically demand.
What to do if you're denied
A denial is not the end. You can appeal, ask your prescriber to submit additional documentation, or switch to a cash-pay route. If cost is the barrier, compare your options in our rundown of the cheapest ways to get a GLP-1.
How do you prepare for the appointment?
A little preparation makes the visit faster and improves your odds of walking away with a prescription.
Bring a weight history
Note your current weight, your highest adult weight, and roughly how long you have been at your current weight. If you have records of past diets or medications, summarize them.
Questions to ask
Ask which specific drug your provider recommends and why, what the starting and target doses are, how side effects will be managed, and what the medication will actually cost you after insurance. For brand-specific access steps, see our walkthroughs on how to get Ozempic and how to get Zepbound.
What if you don't meet the standard criteria?
If your BMI is below the thresholds and you have no qualifying condition, most clinicians will not prescribe a GLP-1, and for good reason: the safety and efficacy data are built around those populations. Reasonable next steps include addressing borderline conditions, revisiting the conversation if your health status changes, or exploring non-GLP-1 options with your doctor. Avoid grey-market sellers that promise a prescription with no real evaluation.
Frequently Asked Questions
Do I need a specific diagnosis to qualify?
Not necessarily. A BMI of 30 or higher qualifies on its own under the labeling. Below that, you generally need one documented weight-related condition such as high blood pressure, type 2 diabetes, high cholesterol, or sleep apnea.
Can a telehealth doctor write a real GLP-1 prescription?
Yes. A licensed telehealth clinician can issue a valid prescription after evaluating you. The prescription is just as real as one from an in-person office, as long as the platform uses licensed providers and a genuine medical assessment.
Will insurance always cover it if I qualify?
No. Meeting the prescribing criteria does not guarantee insurance pays. Many plans exclude weight-loss drugs entirely or require prior authorization, a documented lifestyle attempt, or step therapy. Coverage is often easier when the drug is prescribed for type 2 diabetes.
How long does it take to get a prescription?
Through telehealth it can be same-day to a few days. In person it depends on appointment availability and whether your provider wants labs first. Insurance prior authorization, if required, can add days to a couple of weeks.
