The benefits of weight loss surgery.

Dr Benedict Mackay can help you to take proactive steps to increase your chances of a long, healthy and happy life.
How it Works
Bariatric or metabolic surgery changes the metabolism, resetting the body’s ‘set point’ to a lower weight. It has significantly higher long term efficacy rates than diet and exercise alone because the body self-regulates at that lower weight.
Up to 90% of patients maintain at least 50% of their initial weight loss after surgery. But the overall benefits of weight loss surgery extend much further than simply losing weight. Bariatric surgery has been shown to decrease the risk of heart disease, high blood pressure and some cancers and improve diabetic control.
Recovery from weight loss surgery is fast with most patients returning to work within several weeks. Best of all, eating after surgery should still be enjoyable!
95% of patients improve their quality of life after weight loss surgery. 1
Quality of life

Understanding diseases associated with obesity.

In Australia today, more than 2 out of every 3 adults is overweight or obese. If you are obese, you have a much higher chance of developing serious diseases.
People with obesity have a higher risk of developing comorbidities.

Type 2 diabetes

Type 2 diabetes is a serious condition where the insulin your pancreas makes cannot work properly, or your pancreas cannot make enough insulin. In Australia, 25% of all diabetic patients suffer from obesity.


Hypertension or high blood pressure can result in a decreased oxygen flow to your heart and therefore lead to heart disease. In Australia, 85% of people suffering from obesity develop hypertension.


Dyslipidemia consists of abnormal levels of lipids, such as cholesterol and triglycerides, in the bloodstream that can lead to heart disease. People suffering from obesity are at higher risk of developing dyslipidemia.

Sleep apnoea

Sleep apnoea is a sleep disorder in which breathing repeatedly stops and starts. This can lead to decreased levels of oxygenation, which can lead to cardiovascular disease. Obesity increases the risk of developing sleep apnoea.

Back pain

In Australia, 72% of the people suffering from obesity, experience back pain and related complications.

Best long term results

Obesity care that puts patient outcome first.

Obesity is a chronic disease. Surgery is only part of the cure and it shouldn’t be considered the easy way out. A multidisciplinary approach and regular clinical follow up gives the best long term results for patients.

As part of Weight Loss Solutions Sunshine Coast, Dr Benedict Mackay’s patients have access to 24-hour care, 365 days of the year. Each bariatric operation is conducted at Sunshine Coast University Private Hospital and is attended by two specialist surgeons.

Dr Benedict Mackay works with your GP and a team of allied health professionals, including experienced nurses, dietitians, physiotherapists, exercise physiologists and psychologists, to support you to lose weight and keep it off for good.

Is weight loss surgery right for you?

One of the key criteria for being a bariatric patient is your BMI (Body Mass Index).

According to BMI categories:
40 - 49.9
is obese
is morbidly obese
30 - 39.9
is super obese

Use our BMI tool to find out if your weight is putting you at risk.

Surgery for obesity is considered an appropriate choice for patients:

  • With a BMI greater than 35
  • With a BMI greater than 30 and one or more obesity-related illness
  • Who have tried non-operative weight loss solutions without long-term success

In certain circumstances, patients with lower BMI may be candidates.
