Am I Eligible for Weight Loss Injections? Full Criteria

Checking your eligibility for weight loss injections is the first step before any prescription can be issued.

Wondering about eligibility for weight loss injections? Here’s exactly how it’s assessed before any treatment is prescribed.

Weight loss injections like Mounjaro, Wegovy and Ozempic are prescription-only, which means eligibility is assessed on an individual basis by a clinician — not something you can self-diagnose from a checklist. That said, most providers, including ours, assess similar core criteria. Here’s what’s typically reviewed.

Body Mass Index (BMI)

Most weight loss injections are licensed for adults with a BMI of 30 or above, or a BMI of 27+ alongside a weight-related health condition such as high blood pressure, type 2 diabetes, or high cholesterol. Your prescriber will calculate this from your height and weight during the assessment.

How BMI is calculated

BMI is calculated by dividing your weight in kilograms by your height in metres squared (kg/m²). As a general guide, a BMI under 18.5 is considered underweight, 18.5–24.9 is within the typical healthy range, 25–29.9 is considered overweight, and 30 or above is considered to fall within the obese range. BMI is a useful screening tool but doesn’t account for factors like muscle mass, so your prescriber will consider it alongside your overall health picture rather than in isolation.

Medical history

Your prescriber will ask about conditions that may affect suitability, including:

• Personal or family history of certain thyroid cancers
• Pancreatitis, past or present
• Gallbladder disease
• Severe gastrointestinal conditions
• Pregnancy, breastfeeding, or trying to conceive
• Type 1 diabetes (these medications are generally not indicated for type 1 diabetes)
• Eating disorders, past or present
• Kidney or liver conditions

This isn’t an exhaustive list — the online questionnaire covers your full medical history in more detail, and you’ll always have the opportunity to explain your individual circumstances.

Current medications

Some medications interact with GLP-1 injections, particularly other diabetes medications like insulin. Be ready to list everything you’re currently taking, including over-the-counter supplements.

What happens during our assessment

1. Complete a short online health questionnaire covering your medical history, current medications, and weight loss goals.
2. A member of our clinical team reviews your submission.
3. If appropriate, treatment is approved and prescribed; if not, you’ll be told why and, where possible, offered a suitable alternative.
4. Approved orders are dispatched with discreet packaging, or available for local pharmacy collection.

Frequently Asked Questions

What if I’m not eligible for injections?

If injections aren’t suitable for you, our team may suggest an oral alternative such as Xenical, Orlistat, or Mysimba, depending on your health profile.

Does the assessment cost anything?

The online eligibility assessment itself is free; you only pay if you choose to proceed with a prescribed treatment.

How long does approval take?

Most assessments are reviewed quickly, though timing can vary depending on clinical review volume.

Can I be declined after ordering?

Yes — approval always follows clinical review of your questionnaire, which happens before any prescription is issued.

Is there a minimum or maximum age?

These medications are licensed for adults; specific age criteria and any upper age considerations are reviewed individually as part of your assessment.

How we confirm your eligibility for weight loss injections

Your eligibility for weight loss injections is assessed through a short online questionnaire covering your BMI, medical history, current medications, and any relevant health conditions. A prescriber reviews your answers individually rather than relying on BMI alone, since factors like thyroid conditions, pregnancy, or certain medications can affect whether treatment is appropriate for you right now. If your eligibility for weight loss injections isn’t confirmed on your first assessment, that doesn’t necessarily mean treatment is off the table permanently — your prescriber may recommend addressing a specific health factor first, or suggest a tablet-based alternative such as Orlistat while your situation is reviewed again in future.
