Medical Weight Management FAQ
Straight answers about assessment, support, safety and how Dr Greig’s clinic works.
Who is medical weight management for?
It is for adults who would benefit from a medical assessment of their weight, health risks, previous attempts, medicines and goals. A consultation does not automatically lead to a prescription; sometimes the safest decision is a different approach or further assessment.
Is being overweight a failure of willpower?
No. Weight is influenced by biology, appetite regulation, health conditions, medicines, sleep, stress, environment and many other factors. Telling someone simply to “eat less and exercise more” is often as unhelpful as telling a person with depression simply to cheer up. Good care starts with listening rather than blame.
What happens at the first consultation?
Dr Greig reviews your medical history, previous weight-management experience, current medicines, relevant risks and what you want to achieve. Where treatment is appropriate, he explains the options, likely benefits, limitations and safety issues. You are shown exactly how to use the equipment and how to administer treatment yourself, and you leave with practical written information.
Does my BMI mean that I automatically qualify for treatment?
No. BMI is one screening measure. Some prescription treatments have licensed BMI thresholds, but suitability depends on a full individual assessment. Use the private BMI and waist-to-height checker for an educational result.
Why does Dr Greig ask me to eat three times a day?
Dr Greig’s first golden rule is to eat breakfast, lunch and dinner. The aim is to lose weight while continuing to nourish your body—not to starve. Sudden severe restriction can make people feel very unwell and is neither a functional nor a sustainable way to lose weight. Your food choices can evolve gradually over time.
How much should I drink?
Stay sensibly hydrated and use urine colour as a practical guide: clear to pale straw-coloured urine usually suggests adequate hydration. Excessive fluid intake is not evidence-based and can disturb important body salts. Dehydration can contribute to headache and light-headedness.
What is the two-dose rule?
Order a repeat when you still have two doses remaining. This allows up to 14 days for processing and protects continuity if Dr Greig is away or island supplies are delayed. Repeat requests are for the same medicine and strength most recently prescribed; dose changes or new problems require clinical contact.
What if I develop a side effect or medical problem?
Do not use the repeat-prescription form to report a side effect, dose concern or new medical problem. Contact Dr Greig through the contact page. The website and messaging services are not emergency services; call 999 for a medical emergency.
Am I tied to a particular pharmacy?
No. Clinical assessment and prescribing are separate from dispensing. Castle Quay Pharmacy is convenient for many patients, but you may request to collect your signed prescription from reception and take it to another registered pharmacy.
How quickly will I lose weight?
Responses vary and no responsible clinician can guarantee a particular result. Dr Greig’s approach is a journey rather than a race: protect nutrition, make gradual sustainable changes and review whether treatment remains safe and worthwhile. Historical audit findings are described on the About page with their limitations.
Where can I read about specific prescription treatments?
The separate prescription treatment information page provides balanced factual information and links to current official patient leaflets. Product choice is an individual clinical decision made after assessment.
