A new study reported that people undergoing obesity surgery have a halved risk of death as compared to others who were being treated with diet and lifestyle changes.

Obesity surgery has gained traction as cost effective method and most surgeons claim that more such surgeries need to be undertaken in the UK. Philip Greenland, co-author of the latest study from Northwestern University added that this study is not an impetus to push all obese patients towards bariatric surgery but it provides an extra support to the argument that this surgery might be a better and more cost effective option. The study was published in the Journal of American Medical Association in January 2018.

The team of researchers compared the effects of bariatric surgery with other methods of weight loss. The study involved around 33,540 participants out of which 8,385 had one of the three types of bariatric surgery procedures performed between 2005 and 2014. The three types of bariatric surgery included roux-en-Y gastric bypass, laparoscopic adjustable gastric banding, and sleeve gastrostomy. These participants were all followed up for years and the parameters were compared with obese patients who underwent surgery with three obese patients who underwent non-surgical methods for reduction of weight.

The results showed that death rate of the participants was 1.3 percent among those who had had some form of obesity surgery compared to 2.3 percent among those who had not had the surgery. The team considered other factors such as age, sex and other diseases. However, this was an observational study and the patients were not randomized to surgery or non-surgery groups.

According to Bariatric Surgery Devices Market report published by Coherent Market Insights, bariatric surgery aims to reduce the weight of an individual with the help of a surgery that reduces the size of stomach by removing a portion of tissues or fats of the stomach. Previous studies showed that bariatric surgery was beneficial for patients with diabetes by reducing blood sugar and other parameters. Intensive diet control was tested against bariatric surgery. Results from 113 patients showed that they had better health parameters after the study started including more lost weight, better control of cholesterol, lower blood pressure, and blood sugar.
