GLP-1 medications, such as Wegovy and Mounjaro, are increasingly used to support weight loss and the management of obesity. These treatments work by mimicking the body’s natural hormones to regulate appetite and blood sugar levels, helping many patients achieve significant results. However, it’s important to understand that these medications are strictly regulated and must be prescribed within the boundaries set by their product licenses.
Why BMI Matters
Your Body Mass Index (BMI) is a key factor used to determine eligibility for GLP-1 treatment. According to current UK prescribing guidelines and the medication’s licensing, GLP-1 medications can only be continued while your BMI remains within a specific range. Once your BMI falls outside this range—particularly if it drops below the healthy threshold—prescribers are not permitted to continue treatment.
This is not just a clinical decision, but a legal and safety requirement tied to the way these medications are approved and regulated.
Our Clinical Approach at Pillsorted
At Pillsorted, our prescribers work closely with each patient to ensure treatment is both safe and effective. Our aim is to help you achieve and maintain a BMI within the mid-range of the healthy category—a position that aligns with both optimal health outcomes and product licensing rules.
Here’s what that means in practical terms:
•Mid-healthy BMI typically falls between 21 and 23 for most adults.
•We’ll calculate your target weight based on your height and this ideal BMI range.
•Once you reach this range, we’ll support you in stabilising and maintaining your progress, rather than continuing to lose weight unnecessarily.
What Happens If Your BMI Falls Too Low?
If your BMI drops below the healthy threshold (usually below 18.5), we are legally unable to continue prescribing GLP-1 medication. This restriction protects your health, as excessively low BMI can lead to new medical issues such as nutritional deficiencies, hormone imbalances, and loss of muscle mass.
We monitor your weight and BMI regularly to ensure your treatment remains appropriate and safe throughout your journey.
What You Can Expect
•Regular reviews with our prescribing team
•Clear weight and BMI targets based on your height
•A focus on sustainable lifestyle changes alongside medication
•Advice on maintenance plans to keep you in the healthy range
Final Word
GLP-1 medications can be a powerful tool in your weight loss journey, but they must be used responsibly and within the terms of their licensing. Our team at Pillsorted is here to guide you safely through treatment—from initial prescription all the way to long-term maintenance.
