There are several medications available in Australia for weight loss. We are not allowed to mention the names of the medications due to advertising guideline laws. Your MedSurg Weight Loss Doctor can explain in detail to you the different medications available, how to use them, what side effects you may expect, and monitor you to assess if they are efficacious.
Weight loss medications can be used in patients who:
• have a BMI >30kg/m2*
Or
• have a BMI >27kg/m2 and an obesity related medical condition*
The newer medications available have been revolutionary at addressing overweight and obesity and fill the treatment gap between diet and lifestyle programs and our strongest intervention which is Bariatric Surgery.
Medications can be used with diet and lifestyle changes alone in those with a BMI >27kg/m2 or as an adjunct to other interventions such as the Gastric Balloon or Bariatric Surgery.

Your adult weight is determined by genetic and environmental factors. Your genes program your ‘weight set point’ and your brain is programmed to try and maintain this weight at all costs.
The brain fiercely resists weight loss and will mount a counter-attack against any weight loss a person achieves. It does this by increasing the hunger drive, decreasing the fullness feeling and slowing down the metabolism.
The result is that the person will regain the weight back up to their ‘weight set point’ again, and sometimes can even overshoot the mark, leading to more weight than before, and initiating a new, heavier ‘weight set point.’
People often recognise this pattern and describe it as “yo-yo” weight throughout their life. It’s not for lack of willpower, it all has to do with this very strong battle your brain initiates for you to regain the weight after a weight loss attempt.
The medications interrupt this battle. They mimic hormones within your body that are designed to reduce hunger drive and improve your fullness feeling. They counteract the brains ability to fight the weight loss and allow you to lose weight and maintain it.
There are three different types of weight loss tablets available in Australia. We are not allowed to mention the names of these medications due to advertising guideline laws. These medications work in different ways and your MedSurg Weight Loss Doctor will explain the differences between these medications to you during your consultation.
As a general overview, the medications work by a few different mechanisms, and when used in combination with diet and lifestyle changes can lead to clinically significant weight loss.
Some oral medications work to reduce the hunger drive. Some work by reducing food cravings. Some work by blocking absorption of fats in the digestive system. By understanding your medical history, weight history and psychological history, your doctor can assess which medication would be best suited to you as an individual.
We perform physical, psychological and metabolic testing to ensure that the correct medication is prescribed to the correct person and we help you to navigate any side effects or concerns you have to improve your chances at effective and long term weight loss.
Weight loss injections are prescription medications used to support medical weight management. They work by mimicking natural gut hormones that help regulate appetite, increase feelings of fullness, and reduce food cravings. This makes it easier to eat smaller portions and maintain consistent lifestyle changes.
Weight loss injections may be suitable for adults who are above a healthy weight, particularly if they have weight-related health conditions such as high blood pressure, high cholesterol, sleep apnoea or type 2 diabetes. A doctor will assess your medical history, current medications and previous weight loss attempts before recommending treatment.
When prescribed and monitored by an experienced doctor, weight loss injections are generally safe and well tolerated. Like all medications, they can have side effects, most commonly mild digestive symptoms. Your medical team will explain the potential risks and benefits and monitor you throughout treatment.
Results vary between individuals, but clinical studies show that many people lose a meaningful percentage of their body weight when injections are combined with nutrition, physical activity and behavioural support. Long-term success depends on building sustainable habits alongside medication.
Yes. Weight loss injections are not a stand-alone solution. They work best as part of a comprehensive medical weight loss programme that includes healthy eating, regular movement, sleep and behaviour change support. The medication helps make these lifestyle changes more achievable.
Different prescription medications are available for weight management, including tablets and injections. Injectable treatments are often chosen because they provide strong appetite regulation and are supported by robust clinical evidence. A doctor can help determine the most appropriate option for your individual health needs and preferences.
