The price of NOT having Bariatric Surgery

What is the potential cost of not having Bariatric Surgery?

Bariatric/weight loss surgery does come with a large price tag and for a lot of patients the figure can be very discouraging.  A fundamental area that is not often thought about is what the potential cost of not having the surgery could be on you and our health care system. 

Fear of the social stigma, fear of failing and the cost involved of bariatric surgery, have been just a few other reasons why so many have stuck to more conventional weight loss strategies and are reluctant to have the surgery. Nevertheless, the popularity of bariatric surgery is becoming increasingly popular with patients choosing this ‘tool’ centered option to help with weight loss and long term maintenance.

With the tripling of incidence since 1975, the World Health Organisation estimates that most of the world’s population now live in countries where being overweight and obese kills more people than being underweight. 

The Australian Burden of Disease Study highlights obesity as the second largest risk for fatal disease and largest risk for non‐fatal disease over the past 15 years.  While death rates have been mitigated by a 35% increase in cardiovascular medicine prescriptions and a doubling of diabetes management therapies,  our ability to successfully maintain this approach is likely to be overrun as Australian obesity rates climb to over 40% within a decade. 

Aside from the individual health impact, obesity creates significant community cost implications — direct costs are estimated to be $5.4 billion and indirect costs a further $6.4 billion per year in Australia.  

Let’s look at the disease risk of obesity. 

Bariatric surgery, however, remains the most durable and effective treatment for obesity, achieving in most patients 20–30% total body weight loss (TBWL) for up to 20 years after surgery and improving comorbidities and quality of life. Randomised trials have demonstrated bariatric surgery to be superior in the treatment and control of type 2 diabetes compared with medical management, and improvements in sleep apnoea, high blood pressure, metabolic syndrome, polycystic ovary syndrome, non‐alcoholic steatohepatitis and arthritic disease have been extensively documented. Most compellingly, matched cohort studies have demonstrated clear reduction in all‐cause mortality for patients with obesity undergoing bariatric surgery, with particular decrease in cardiovascular and cancer death compared with their non‐operated cohorts. These health benefits translate to substantial health care cost savings, the magnitude of which is equivalent to smoking cessation.

Savings in the long term

Yes, it is true that the decision to have bariatric/weight loss surgery will mean spending more money on items such as new clothing, dietary supplements, fitness and check-up appointments, but you will see significant savings are gained in your food bill, medication and medical bills.  

In conclusion, bariatric surgery pays off in the long-term, financially, physically, mentally and reduces the burden on our already overloaded health care system.
