Thanks Nancy, see below for how the BBC is reporting it.
Note the casual dismissal of the doubled risk of fractures by Dr David Haslam, of the National Obesity Forum.
Compare and contrast to the constantly repeated false allegation that low-carb is dangerous because it lowers bone density.
Also consider that if reduced Vitamin D absorption can have this affect on bones, what else is getting broken that is not so obvious as a broken bone?
It seems that bariatric surgery (which I think should be called "intentional abdominal mutilation") will be presumed safe until it is proved dangerous. Whereas for some unknown reason low-carb is subjected to an opposite standard of proof, and is presumed dangerous until proved safe.

Obesity ops 'raise fracture risk'
Obesity increases the risk of conditions such as cancer and diabetes
People who have obesity operations, such as gastric bypasses or banding, double their risk of suffering fractures, US research suggests.
Researchers for the Mayo Clinic in the US reviewed nearly 100 surgical cases spanning 21 years for their study.
They found a fifth of patients suffered fractures - twice the rate typical for their age - with most breaks occurring in the bones of the hands and feet.
The findings will be presented at the Endocrine Society Annual Meeting.
In the study, 21 individuals experienced 31 fractures within an average of seven years after their weight loss or bariatric surgery.
The results of our study show that patients who have had bariatric surgery have a two-fold risk in developing a fracture or sustaining a fracture as compared to the normal population
Lead author Dr Elizabeth Haglind
While most breaks were in the hands and feet, fractures of the hip, spine and upper arm bone - the humerus - were also reported.
Experts already know that there is extensive bone turnover and loss of bone density after bariatric surgery, but it was unclear whether that translated to fractures.
Lead author Dr Elizabeth Haglind said: "We've shown that risk of fractures after this type of weight-loss surgery is clinically significant.
"The results of our study show that patients who have had bariatric surgery have a two-fold risk in developing a fracture or sustaining a fracture as compared to the normal population."
Bone health
She said more research was needed to confirm the findings and understand the specific risk factors and mechanisms involved.
Both obesity and weight-loss surgery are known to affect bone health.
Chronic vitamin D deficiency and inadequate calcium intake are common with obesity, and bariatric surgery poses a risk owing to malabsorption and decreased oral intake.
Dr David Haslam, of the National Obesity Forum, said although bariatric surgery might increase future fracture risk, this risk was likely to be far outweighed by the health benefits of the surgery in terms of reduction in weight and obesity-related conditions, such as cardiovascular disease and diabetes.
"For these reasons, the increase in risk is probably not worth worrying about. But we do need more study."
