Do You Qualify for a GLP-1? BMI Requirements Explained (2026)

To qualify for a GLP-1 for weight loss, you generally need a BMI of 30 or higher — or 27 or higher with at least one weight-related health condition. That's the standard threshold for semaglutide (Ozempic, Wegovy) and tirzepatide (Mounjaro, Zepbound), brand or compounded. But the question most guides skip is the one people actually worry about: what happens after you've lost weight and your BMI drops below the cutoff? The short answer is that you don't automatically have to stop. Here's how qualification actually works — both to start and to continue.

Important: this is general information, not medical advice. Whether a GLP-1 is right for you, to start or to continue, is a decision your prescriber makes based on your full health picture.

Not sure if you qualify, or worried you'll get bounced at intake? The fastest way to find out is to start an eligibility check with a provider — it takes a few minutes and there's no charge to see if you're approved. See the best verified GLP-1 providers, or start with the lowest verified price at Embody (from $69/mo). Some compounded providers don't apply a strict BMI floor at all.

What BMI do you need to qualify for a GLP-1?

The standard clinical criteria, used by nearly every legitimate provider:

This is the same framework whether you're getting brand-name Wegovy/Zepbound or a compounded version, and it's the same for semaglutide and tirzepatide. (For type 2 diabetes the criteria are different and BMI-independent — Ozempic and Mounjaro are prescribed based on your diabetes, not your weight.)

Not sure of your BMI? It's your weight in pounds divided by height in inches squared, times 703. A 5'6" person weighing 186 lbs is right at a BMI of 30.

What counts as a "weight-related condition"?

If your BMI is between 27 and 30, one of these qualifies you:

• High blood pressure (hypertension)
• High cholesterol (dyslipidemia)
• Prediabetes or type 2 diabetes
• Obstructive sleep apnea
• Cardiovascular disease
• PCOS (polycystic ovary syndrome)
• Non-alcoholic fatty liver disease

If you have one of these, you're eligible at a BMI as low as 27. It's worth mentioning any of them during your intake — they can be the difference between qualifying and not.

Do you still qualify after losing weight?

This is the question almost no guide answers, and it's the one that causes the most anxiety. You've done the work, lost the weight, and now your BMI is under 30 (or under 27). Do you have to stop?

No — you generally don't. Continuing a GLP-1 after you reach a healthy weight is standard, evidence-based practice. GLP-1s treat a chronic condition; they aren't a temporary diet. In the STEP-4 trial, people who stopped semaglutide regained about two-thirds of their lost weight within a year, while those who continued kept it off. Your prescriber weighs the benefit you're getting against your current numbers, and "maintaining a hard-won weight loss" is a legitimate reason to continue.

Practically, here's how to keep going without getting auto-rejected at intake:

• Enter your STARTING weight (the one that qualified you), not just your current weight. Most intake forms ask for both, or have a notes field.
• Say you're a continuing patient already established on the medication — you're not a new start, so the initial-eligibility screen shouldn't apply the same way.
• Mention any qualifying condition you have (see the list above) — that keeps you eligible even at a lower BMI.
• Consider a maintenance dose. Many people drop to a lower dose to hold their weight rather than keep losing. Ask your prescriber what that looks like for you.

What if your BMI is under 27?

This is where honest guidance matters:

• If you're an existing patient who lost weight below 27, continuation for maintenance is still a conversation to have with your prescriber — the STEP-4 data supports it.
• If you're brand new and under 27 with no qualifying condition, most legitimate providers won't (and shouldn't) prescribe a GLP-1 purely for cosmetic weight loss — and you should be cautious of any that will, since that's the marketing the FDA has been cracking down on.
• "Microdosing" at a low BMI gets discussed in some communities, but it's off-label and not something to pursue outside a prescriber's guidance.

Brand vs compounded: does qualification differ?

The clinical criteria are the same, but the *practical* path differs:

• Brand-name (Wegovy, Zepbound) through insurance requires your insurer's prior-authorization rules, which often demand documented BMI, failed diet attempts, and sometimes step therapy.
• Compounded through cash-pay telehealth applies the same BMI/comorbidity clinical judgment, but without needing an insurance diagnosis code — and a few providers don't set a strict BMI floor. This is often the more accessible route if you're between 27 and 30, or continuing after weight loss.

How to get started (or keep going)

If you think you qualify — or you're a continuing patient worried about re-qualifying — the move is simple: start an intake and let a licensed clinician make the call. It's free to check, and you'll usually know within a few days.

Compounded semaglutide runs about $69-$99/month and compounded tirzepatide about $119-$150/month cash, far below brand prices, from verified US telehealth providers. Here's the cost landscape:

FAQ

What BMI do you need for semaglutide or tirzepatide? A BMI of 30 or higher, or 27 or higher with at least one weight-related condition (high blood pressure, high cholesterol, prediabetes, sleep apnea, PCOS, and others). The same threshold applies to Ozempic, Wegovy, Mounjaro, Zepbound, and their compounded versions.

Do I have to stop my GLP-1 once my BMI drops below 30? No, not automatically. Continuing for weight maintenance is standard practice — stopping usually causes regain (people in the STEP-4 trial regained about two-thirds of their loss within a year). Your prescriber decides based on your ongoing benefit.

How do I keep getting my GLP-1 if my BMI no longer qualifies? Enter your starting weight at intake, note that you're a continuing patient already established on the medication, and mention any qualifying condition you have. Some compounded providers don't apply a BMI floor at all.

Can I qualify at a BMI of 27? Yes, if you have at least one weight-related health condition — high blood pressure, high cholesterol, prediabetes, type 2 diabetes, sleep apnea, PCOS, fatty liver, or cardiovascular disease.

Can I get a GLP-1 if my BMI is under 27? Generally not as a new patient without a qualifying condition — legitimate providers won't prescribe it purely for cosmetic weight loss. As a continuing patient maintaining a weight loss, it's a conversation to have with your prescriber.

Does compounded have different qualification rules than brand? The clinical criteria are the same, but compounded cash-pay telehealth doesn't require an insurance diagnosis code or prior authorization, and a few providers don't set a strict BMI floor — often the more accessible route.

The bottom line

Qualifying for a GLP-1 comes down to a simple threshold: BMI 30+, or 27+ with a weight-related condition — the same for semaglutide and tirzepatide, brand or compounded. And if you've already lost the weight, you generally don't have to stop: continuation for maintenance is standard, and the trick at intake is to enter your starting weight and flag that you're a continuing patient.
