Everything You Want to Know
Have questions about our weight loss program? Here, we answer common queries about safety, personalised plans, and what to expect on your journey, so you can start with confidence.
What happens during my first consultation?
Your first consultation includes a full review of your medical history, lifestyle, and weight goals. Our doctor will assess your needs and recommend a personalised plan designed to support safe, effective, and lasting results.
Are the treatments or medications safe?
Yes. All treatments are clinically approved and prescribed only after a full consultation and health assessment. Our programmes are also doctor-led and adhere to strict medical guidelines.
Is this programme suitable for everyone?
The program is designed for adults with weight-related concerns, or obesity-related health risks. Our doctor will assess your suitability during your consultation to ensure it’s safe and effective for you.
Will I need to change my diet or exercise routine?
You’ll receive guidance on healthy habits that complement your personalised plan. While major changes aren’t always necessary, small lifestyle adjustments can enhance results and support long-term weight management.
How soon will I see results?
Results vary depending on your body, lifestyle, and adherence to your personalised plan. Many clients notice improvements within the first few weeks, with ongoing progress supported by regular monitoring.
What’s the difference between oral and injectable weight loss options?
Injectables work through direct absorption, while oral options provide a needle-free daily routine. Your doctor will recommend the most suitable choice for your health and goals.
Can anyone take weight loss options?
Not everyone is suitable. Eligibility is determined by our doctor based on your medical history, BMI, and overall health.
