Weight deprivation surgery , orbariatric surgery , may not just avail you pour forth the pounds in the short - term – it may in reality strike your body ’s collection of germ   and help stave off corpulency in the long - term .

That ’s accord to enquiry that investigated the effects of weight loss surgery after almost a decennium . The squad from the University of Gothenburg in Sweden studied 14 womanhood who had undergone two form of surgery nine year antecedently , Roux - en - Ygastric ring road andvertical banded gastroplasty . Both were find to alter the body’smicrobiome .

In the inquiry , published in the journalCell Metabolism , microbes from the stool sample of women who underwent these surgical process were transplanted into specially bred “ germ - free ” mouse that were barren of any gut bacteria . Microbes from a freestanding group of   obese women who had not undergone bariatric operating theater   were also transfer into similar black eye via the same method acting .

It was discover that those mice collapse the germ from the cleaning lady who had operating room gain less weighting than the other mice . While both gained weight watch the transplant , the mice render the post - surgery bug from Roux - en - Y and vertical banded gastroplasty patients gained 43 % and 26 %   less fat severally than the mastery group . This may have been due to the slimmer mouse cut fewer carbohydrates and more rich   than the control group , but the exact microbes at play are not yet known .

" Our findings are important in illumination of the develop epidemic of fleshiness and associated diseases , " said Fredrik Bäckhed of the University of Gothenburg , who lead the enquiry , in astatement . " Since surgery always confers a risk , it is critical to place non - operative strategy . One possible scheme would be to devise novel probiotics free-base on our findings that can be cater to weighty soul . "

The determination suggest that the achiever of bariatric surgery – which includes reducing the size of a stomach with a gastric circle or removing part of the abdomen – may in part be due to this lesser - known microbiome effect , rather than just the surgery itself . This mean that , in futurity , it might be easier and more beneficial to treat obesity by transplanting these weight - loss - consociate bug , rather than do the complicated , expensive   and at times risky function .

The problem now will be to work out which of the 1,000 types of bug in our intestine are actually responsible for this apparent core . If that can be narrow down , it could have huge implications for treat obesity in future .
