Weight loss injections in Australia

Lose up to 20% body weight with clinically proven treatments2

Obesity is a complex metabolic condition influenced by factors such as genetics, epigenetics, hormonal imbalances, metabolic dysregulation, digestive issues, age, medication interactions and other health conditions, including mental health.

Prescription weight-loss injections alter hormonal responses related to metabolism and digestion, leading to reduced hunger and better metabolic regulation (1). They are typically recommended for individuals with a Body Mass Index (BMI) of 30 or higher, or those with a BMI of 27-30 who have weight-related health conditions (4).

How Do Weight Loss Injections Work?

The science behind weight loss injections is rooted in their ability to mimic the actions of a hormone called GLP-1, or glucagon-like peptide-1. This hormone helps regulate aspects of your metabolism, particularly when managing appetite and digestion. Three ways weight loss injections aid in weight loss are:

Regulating Appetite

GLP-1 is a hormone naturally produced by the body, primarily in the intestine. It acts as a messenger, sending signals to the brain to regulate appetite. When GLP-1 levels rise, as they do with the use of weight loss injections, they tell the brain that you’re satisfied and lessen feelings of hunger. This appetite-regulating effect can be particularly beneficial for people who tend to overeat or have constant cravings (1).

Increasing Feelings of Fullness

In addition to reducing hunger, GLP-1 enhances feelings of fullness or satiety. When this hormone is active, it encourages the sensation that you’ve had enough to eat, which can lead to decreased food intake. By mimicking the action of GLP-1, these medications help you consume fewer calories without constantly battling the urge to eat (1).

Slowing Digestion

Another vital role that GLP-1 plays in weight management is slowing down the emptying of the stomach. This means that food stays in the stomach longer, leading to a sensation of fullness that persists after a meal. When digestion is slowed, you are less likely to experience rapid spikes in hunger shortly after eating, which can lead to snacking and overeating (1).

How Effective Are Weight Loss Injections?

Using weight loss injections, the average person may lose up to 13% of their body weight in just one year. (1)

Weight loss injections have demonstrated significant efficacy in clinical trials. In a 72-week study, participants using a GLP-1 receptor agonist lost an average of 15-21% of their body weight, compared to a 3.1% reduction in the placebo group (1). Another study showed that an injection administered at 2.4 mg once weekly resulted in a mean weight reduction of 14.9% over 68 weeks, compared to 2.4% with placebo (2). Additionally, a third treatment showed substantial weight loss in patients with and without Type 2 diabetes, with participants losing about 8% of their body weight compared to the placebo group (3).

Individual responses to these medications can vary, and they should be part of a comprehensive weight management plan that includes balanced eating and regular physical activity for long-term weight loss (4).

How long until you see results?

The timeframe for seeing results from weight loss injections can vary based on factors like medication type, dosage, response, food choices, activity levels, and starting weight. While some may notice reduced hunger within weeks, significant weight loss usually takes several months (5). Be patient and follow your treatment plan. 

Our health-first approach focuses on benefits like improved sleep, reduced stress, more energy, better mood and cognition, better pathology markers (cholesterol, BP, HR), and non-scale metrics such as better fitting clothes, improved skin, and healthier hair and nails. Your healthcare provider can give you a clearer expectation of what to expect for your circumstances.

How do you take weight loss injections?

The method of administering weight loss injections depends on the medication type. Some medications come in vials and require patients to draw up the medication using syringes before injecting. Others use pen-like devices with small, painless needles, typically injected in the upper thigh or abdomen. The frequency of injections varies based on your doctor’s prescription, generally ranging from once daily to once weekly. It’s important to follow your doctor’s dosing schedule and instructions carefully to limit the risk of side effects.

Are there side effects of weight loss injections?

The common side effects of weight loss injections are mainly gastrointestinal (GI) issues, including nausea, diarrhoea, vomiting, and stomach pain (1,2,3). Some people may also experience headaches, fatigue, dizziness and decreased appetite (1,2,3). These symptoms are generally mild to moderate in severity and often improve over time as the body adjusts to the medication. 

There are also rare but serious risks such as pancreatitis, thyroid tumours, and gallbladder-related issues like cholecystitis (1,2,3). While these medications offer valuable benefits, further studies are needed to confirm their long-term safety and efficacy. If prescribed weight loss injections with, your clinician will offer guidance on managing common side effects and adjusting your treatment if necessary.

Frequently asked questions

The weight loss injections we prescribe contain one active ingredient. When injected, this active ingredient mimics the effects of a specific hormone in the body that helps to reduce appetite, increase feelings of fullness, and slow stomach emptying, leading to a reduced calorie intake that ultimately promotes weight loss.2

It’s important to note that these medications are prescription-only and should only be taken under the guidance of a healthcare professional in conjunction with a healthy diet and exercise program.
The results of weight loss injection treatments can vary depending on the specific medication, individual factors such as age, gender, and medical history, and personal adherence to a healthy lifestyle. However, some general potential benefits that may be associated with these weight loss treatments include:

  • Physical health improvements to important health markers, such as blood pressure, blood sugar levels, cholesterol levels, sleep quality, and joint pain, and a reduced risk of developing obesity-related diseases, such as heart disease, stroke, and type-2 diabetes.
  • Mental health improvements, such as improved self-esteem, mood, and confidence, and reduced symptom severity of depression and anxiety.
  • Improved quality of life, including increased energy levels, better mobility, and the ability to engage in activities that may have seemed off-limits due to excess weight.
  • Weight reduction has been shown in several studies. However, the amount of weight loss can vary depending on the duration of treatment, and personal adherence to a healthy lifestyle.2

It’s important to note that weight loss meds are not a magic solution. They must be used in combination with a healthy diet and regular exercise for the best results.
