“The good physician treats the disease. The great physician treats the patient who has the disease.”
Sir William Osler
Everybody is talking about the new “miracle” weight-loss drug. It is in the news, all over social media and the celebrity gossip, and at the next table at the restaurant. Your friend swears by it. Your cousin felt awful on it and stopped. And these days a script is only a few clicks away online. Many of us are wondering, “Would it help me too?”
A quick note on names. By law we cannot advertise prescription medicines to the public, so you will not see brand names here. The medicines we are talking about are the once-a-week weight-loss injection pens, a group called the GLP-1 receptor agonists. If a particular brand name just came to mind, that is almost certainly the one.
What these medicines actually do
GLP-1 is a hormone your own gut makes after you eat. It tells your brain you are full and slows how fast your stomach empties. These medicines are a long-acting version of that signal. For many people the effect is a noticeable quieting of what patients often call “food noise,” the constant low hum of thinking about the next meal. Portions shrink, snacking eases, and for the first time in years some people feel less at war with their appetite.
These medicines are not willpower in a pen. They work at a fundamental level of the body, deep in the hormonal machinery that steers our unconscious behaviour, which is why the change can feel strange to people who have spent decades fighting their appetite consciously. And it is not just the food noise they slow down. The same signal slows the gut itself, and a stomach that empties slowly changes more than hunger. It changes how food sits, how some other medicines are absorbed, and even how you should be prepared for an anaesthetic if you ever need an operation. These are the details that you might not see on social media.
A medicine that works this deep is not one to start on a hunch. The best way to answer “Would it help me too?” is by speaking with your GP, who will take the time to understand your whole story, not by a telehealth questionnaire built to end in a sale. Answer it properly and you get what the quick version skips: a careful check of your health first, a plan built around you, and a team that stays with you.
That is the conversation we would love to have with you, whether you are just curious, nearly decided, or already taking it. We cannot answer the question in an article. It depends on your health, your history, your goals and your budget, and we work that out with you, not for you. What we can do here is show you the rest of how we think it through, because how the question gets answered matters almost as much as the answer.
What they can genuinely offer
In the major trials, many people lost somewhere between five and fifteen per cent of their body weight, and with that came the well documented benefits of carrying less weight: better blood pressure, easier breathing at night, less load on sore knees and hips, and lower heart risk. For someone who has spent decades trying but not getting traction, that can be life-changing.
The most important detail behind the remarkable success of these medicines in the trials, and the mixed bag in real life, is that in the trials the medicine never worked alone. Every participant had a structured support program wrapped around the injection, with food and movement addressed alongside it and regular follow-up built in. We can help you understand the medicine and your body, and build that support program around you.
Where you may come unstuck
The most common side effects are understandably gut related: nausea, vomiting, diarrhoea or constipation, bloating and reflux. For most people they are worst when starting or stepping up the dose, and they settle. Going slowly helps. A smaller group find them intolerable enough to stop altogether.
Less often, something more serious happens, and these are the ones we want you watching for. Severe ongoing tummy pain, especially with vomiting, can signal a problem with the pancreas or gallbladder. That is a reason to contact us or go straight to the emergency department, not to wait. One thing many people may not expect is the increased risk with an anaesthetic. If you are booked for an operation or any procedure with sedation, tell the team you are on one of these medicines, because they slow the stomach and the anaesthetist needs to know. There have also been reports of low mood in people taking these medicines. The evidence so far does not show the medicine is the cause, but regulators have asked doctors to watch for it, and we can help early if your mood shifts.
They are not right for everyone. A history of certain thyroid cancers, pancreatitis, pregnancy or planning one, and some eating disorders all change the picture. They are not cheap either. For weight loss they are not currently subsidised by the PBS, so most people pay privately, in the order of several hundred dollars a month. There is movement on that front. The government has committed to subsidising one of these medicines for people with established heart disease plus obesity or a very high body mass index, which would drop the cost to the standard PBS co-payment: $25 a script, or $7.70 with a concession card. At the time of writing, the listing is still being negotiated on price, so it is close but not here yet. We will let you know when it lands.
And what happens when you stop? The appetite signal seems to switch back on. In one of the key studies, people regained about two-thirds of the lost weight within a year of stopping. Substantial rewiring of this fundamental level of our biology can never simply be a twelve-week project. Weight loss is a long-horizon treatment for a chronic health condition.
The script is only a part of the journey
Here is the part we most want you to take away. The medicine may make you desire food less, but it does not cause you to make healthy choices. It does not encourage you to exercise, to send the stimulus to your muscles and bones that keeps them strong. It does not help you handle the social situations when you do not behave the way you used to, among friends and family who may not be on the same journey as you.
We now have several years of real-world data on these medicines used the quick way. Without additional support, people lose on average about half of what the trial participants lost. Same medicine, same expense, half the result. About half of people stop within the first year, usually over cost or side effects nobody helped them manage, and most never reach the dose that did the work in the studies. The people who stayed the course at a proper dose had the greatest success.
Staying the course is not a personality trait. Knowledge is power. Success is what happens when the dose steps up at the right pace, the rough fortnight is managed instead of endured, your eating adjusts so the weight you lose is the weight you want to lose, and a coaching team who knows your whole picture is checking how you are travelling. A place where support is part of the treatment.
How we do it here
So a first conversation with us is a proper look at the whole picture, because weight is rarely one problem. Medicines that quietly add weight, sleep apnoea, thyroid conditions, mood, and long-standing eating patterns all shift what success should look like for you. Finding them first is what stops six months of honest effort pointing at the wrong target. It is also where we check the safety questions above, and where we say so plainly if this is not a sensible fit. For some people it clearly is. For others it clearly is not, and we will tell you so.
If we do start, you are not left alone with a weekly injection and a shrug. Our nurses help with technique and tracking. Food, movement and mood are core general practice, so your GP may be all the coaching you need. Where specialised input would help, we can refer you to a dietitian to optimise nutrition, to an exercise physiologist so you can hold onto muscle while the weight comes off, or to a psychologist to help manage the thoughts and feelings that this profound journey can awaken, often with Medicare support through chronic condition or mental health care plans. Your GP keeps the whole thing joined up, reviews progress with you, and helps ensure you improve your health rather than simply lose weight. And if and when you come off the medicine, you have built the kind of life and support around you that enables continued good health.
The quote at the top is there on purpose. The disease is easy to describe. The patient who has the disease is you, with your history, your knees, your budget, your kitchen and your reasons. You are who the treatment needs to fit, and we can tailor a health program that works for who you are.
If you are wondering about these medicines, or have already started them but want some additional help, we would love to help you think it through. Book a longer appointment so we have time to do it properly: what you are hoping for, the costs, the alternatives, and whether it fits you. Book online or call reception on 8389 1009.
