What it is
The pathway begins with a medical assessment: a proper history, an examination, and usually blood tests. Dr Ong is looking for the whole picture, including anything that is driving the weight (medications, sleep, thyroid and metabolic factors), anything the weight is driving in return, and whether prescription treatment is medically indicated. Nothing is prescribed at this stage, and sometimes the assessment is the whole visit.
Where the indication supports it, treatment may include structured lifestyle work and prescription medicines, most commonly the GLP-1 receptor agonists and the newer dual agonists that act on GIP and GLP-1 together. In plain terms, these medicines mimic gut hormones that signal fullness, so appetite quietens and smaller meals satisfy. They are prescription-only medicines, prescribed after a full evaluation, and the choice between them depends on the medical picture, the goals, and what suits the individual patient.
The medicine, where it is used, is one part of a plan. Food, movement, sleep and follow-up visits carry the rest, because they are what the result stands on when the dose is eventually reduced. Monitoring continues for as long as treatment does.
What it does well
Medically indicated weight loss, supported by supervision that does real work. This is for patients whose weight is affecting their health, patients where weight is feeding other clinical problems, and patients who have made honest attempts before and found the weight returning, which is common and has more to do with biology than with willpower.
The newer medications changed what this category can honestly offer. The evidence base for the class is substantial, and for many patients the weight loss is large enough to matter clinically, which is exactly why these medicines deserve respect rather than casual use. Supervision is where that respect shows: doses are raised at a pace the body tolerates, side effects are managed early, and progress is reviewed against the expectations set at assessment instead of against an advertisement.
What it does not do, and who it is not for
This is not a quick cosmetic slimming service, and it is not suitable for everyone who asks for it. A patient already at a healthy weight who wants to be smaller for a wedding or a photograph is asking the medicine to do a job it was never designed for, and the answer will be no. A patient near target weight with one stubborn pocket has a body contouring question, which is a different category with different tools.
Some patients should not have these medicines at all. They are not used in pregnancy, while planning a pregnancy, or while breastfeeding. A history of disordered eating calls for a different and more careful conversation, sometimes with another specialist first. A small number of medical histories rule the medicines out entirely, which is part of what the assessment screens for, and patients on multiple medications need interactions considered before anything is added.
The medicine also has limits worth stating. It does not choose your food, build your habits, or protect your muscle on its own, and it is well documented that weight tends to return when medication stops with nothing else changed. A patient who wants the injection without the follow-up, the monitoring or the rest of the work is asking for the version of this treatment that fails, and the clinic does not offer that version.
Our view
Weight management has changed substantially with the newer generation of medications, and the change is genuine. That is exactly why the category needs holding. Medicines this effective attract commercial pressure, and the line between appropriate use and overuse does not hold itself; it has to be held by the prescriber.
Dr Ong's role is to prescribe where the medicine fits, monitor properly, and decline where it does not. The declining matters as much as the prescribing. A prescription that should not have been written does not become safer because the patient asked politely. Weight is medicine, and it deserves to be treated like medicine.
Practical notes
The first visit is a thorough medical consultation, longer than a typical aesthetic appointment, and usually includes blood tests. Treatment does not always begin the same day; where results are needed, the plan is confirmed once they are back. Bring a list of your current medications and any relevant medical history, since both shape what can be prescribed.
If treatment proceeds, subsequent visits cover monitoring, dose adjustments, side effect management and ongoing support, at a frequency set for the individual patient. Which medicine, at what dose, on what schedule, are decisions made in person after assessment, and revisited as the response becomes clear. Specifics are discussed in the room, where they belong.
