The number of overweight people going through weight loss surgery has doubled in the last five years. According to Obesity Surgery Society of Australia and New Zealand (OSSANZ), more than 7500 went through weight loss surgery last year. Latest report from Organization for Economic Co-operation and Development found Australia suggests that Australia is on the fifth place in obesity rate among adults in the developed countries. One out of every five adult is obese here in Australia – triple the number of obese twenty years back.
The study was carried out on 2000 obese people who had gone through surgery and another 2000 people whom weight was being managed by lifestyle factors such as diet. After 10 years it was found that twice as many people in the non-surgical group died from heart attack and another 47 people diet of cancer compared to 29 people in the surgery group.
Professor Jeff Hamdorf, from the medical education faculty at the University of Western Australia, said the study "really shows how effective surgery can be for obese people who have not been able to lose weight any other way."
Right now, people with BMI greater than 35 are recommended for weight loss surgery. Bt according to Professor Hamdorf, weight loss surgery should be allowed to people with a BMI greater than 30.
Sarah Fisher, who is a nurse from Lane cove, had gone through gastric band surgery last year and since then her total weight have fallen from 115kgs to 77kgs. "I tried every diet but nothing worked. I suffered asthma, osteoporosis and depression," she said. "After surgery, the weight fell off. The improvement in physical and psychological terms has been phenomenal."
With improved surgical techniques, there are many risk factors involved as well.
