Take the First Steps Towards a Healthier Lifestyle

Do you struggle with long-term excess weight and failed diets? Despite talking to a bariatric physician are you still unable to hit your weight loss goals? Maybe surgical weight loss options could be the most effective way for you to make a life-changing difference to your weight and overall health.

Obesity surgery is the fastest, most effective way to quickly reduce your exposure to sleep apnea, high blood pressure, cancer, stroke and many more obesity-related diseases. This is because it allows obese individuals to use an integrated approach. Certain lifestyle changes become easier after surgery such as eating fewer calories and exercising, and consequently, the likelihood of long-lasting weight loss is increased substantially.

Let Us Guide You Along a Weight Loss Journey

Like any general surgery, weight loss surgery involves a significant decision. Which surgery is right for you, if any at all, comes down to your medical history. This is why everyone that chooses Perth Obesity Solutions for their obesity surgery receives a bulk billed consultation where you can ask further questions, inform us of any medical conditions and we can discuss your weight loss goals.

Find Out If You Are Eligible for Bariatric Surgery.

If you are overweight or obese, you have probably tried a range of ways to manage your weight. From restrictive diets to targeted training, there are plenty of programs that promise great results. But these won’t work for everyone and are often simply unsustainable. Bariatric surgery overcomes these issues and has been proven to provide lasting results.

If you have a BMI of 30+ you may qualify for bariatric surgery

Understand the Dangers of Obesity

Bariatric surgery for some is the silver bullet to their problems of obesity and weight regain after failed diets. If you are dealing with any of the following weight-related illnesses then our skilled bariatric surgeons and state-of-the-art bariatric surgery in Perth could be the life-changing solution you have been searching for.

Learn More About Obesity

Heart Disease

Heart disease covers a range of different illnesses related to your cardiovascular system. It includes coronary heart disease, stroke, peripheral arterial disease and many more heart-related illnesses. Heart disease is a common illness amongst those with both obesity and morbid obesity and can lead to dire circumstances if not managed. For this reason, weight loss surgery can provide quick preventative measures and life-saving results.

Sleep Apnoea

We spend a third of our lives sleeping, so it is no wonder that sleep is essential for leading a healthy life. It is responsible for producing hormones that make us hungry, and hormones that make us feel full. It keeps blood pressure down and energy levels up. So it is no wonder that poor sleep quality such as that created by sleep apnoea would greatly reduce not only our ability to live healthily but our ability to lose weight! If you are struggling with sleep apnoea it could be causing a vicious cycle that needs a little extra help to break.

High Cholesterol

Cholesterol is essential to a functioning body. They are responsible for the creation of healthy cells and hormones, and they assist with the digestion of food. But like many things in life, it is only safe in moderation. High cholesterol levels cause our blood to thicken, making it harder to pump through our bodies and leading us to a life of increased risk of heart failure or stroke. Bariatric surgery can help those with high cholesterol by reducing the size of their stomach so that they eat fewer calories and thus reduce the amount of fat in the blood.

Type 2 Diabetes

Type 2 diabetes affects 5% of Australians aged 18 and over (roughly 1 million adults) and is one of the fastest growing illnesses world wide. Thankfully, type 2 diabetes can largely be avoided by staying within a normal weight range, eating fairly healthy and exercising regularly. However, even with the avoidable nature of the illness, for some the above preventative measures are not currently achievable, eating healthy is hard when your stomach has expanded and exercising can be painful when you are obese. The key to making all of these preventative measures achievable is reaching a normal weight range, this is where the decision to undergo surgery could be the difference between a life with or without diabetes.
