Who Can Get Prescription Weight Loss Injections?
Weight loss injections are prescribed for adults who meet specific clinical criteria rather than anyone who wants to lose weight. Before treatment is recommended, a healthcare professional will review your overall health, medical history, and weight management goals to determine whether prescription medication is appropriate.
During your assessment, clinicians typically consider:
- Body Mass Index (BMI) and current body weight
- Weight-related health conditions, such as high blood pressure or obstructive sleep apnoea
- Previous weight loss attempts through diet and physical activity
- Existing medical conditions and current medications
- Whether treatment can be used safely alongside long-term lifestyle changes
Meeting the eligibility criteria does not automatically mean one treatment is suitable for everyone. A personalised clinical assessment helps identify the most appropriate option based on your individual health profile and treatment goals.
