Medication for Weight Loss: Supporting Your Journey
There is no ‘silver bullet’ to achieving lasting, healthy weight loss. On the contrary, weight loss must be considered in the context of a combination of complex physical and mental health and lifestyle factors, all working together to address the root cause of your excess weight.
At Obesity Surgery WA, we understand that achieving a healthy weight can be challenging. For those who struggle with diet and exercise alone, medically-guided prescription weight loss treatments can provide valuable support. Designed to work alongside lifestyle changes, these medications help you achieve sustainable results safely and effectively.
Prescribed weight loss medications, in tandem with diet and lifestyle changes and under the guidance of and with the support of medical specialists, can make a real difference in achieving long term success with your weight loss program.
Diets to help you lose weight
Diets can be an effective starting point for weight loss for many, helping to shed excess kilos in the short term. To sustain these results, though, building sustainable healthy habits and gaining a better understanding of calorie content in foods (and how they can impact your weight), can help pave the way for long-term success and a more balanced lifestyle.
Our Perth dietitians offer a wide range of diets to help you lose weight, and they will work with you to tailor a program to your individual needs.
It’s vital that any weight loss program be medically supervised.
When considering weight loss medication, it's important to understand that the effectiveness of available medications differs for different people. As such, carefully trialling medication under the supervision of your doctor to understand which one, or which combination, is the most appropriate for you, is vital.
How do weight loss medications work?
Controlling Appetite
These medications help reduce hunger and curb cravings by influencing appetite-regulating hormones or brain signals.
Enhancing Satiety
They promote a feeling of fullness, so you eat less and stay satisfied longer, reducing overeating.
Supporting Metabolism
These drugs improve how your body processes food and energy, boosting calorie burn or reducing fat storage.
Who are weight loss medications suitable for?
Weight loss programs that potentially integrate prescription medications are typically suitable for individuals with:
- A BMI of 30 or higher
- A BMI of 27 or higher and an accompanying weight-related condition such as type 2 diabetes or high blood pressure
In Western Australia, a BMI of 30 or higher is classified as obese.
