Weight-loss surgery may affect bone density: study

Weight-loss surgery may affect bone density: study

BEFORE surgeons removed a large part of her stomach to help her lose weight, Vanessa Hall asked her doctor what affect the procedure would have on her body by the time she turned 80.

His answer, she said, was: ”We don’t know. We don’t know what happens.”

And therein lies the dilemma for the 17,000 people the Australian Bureau of Statistics says undergo the procedure each year – little is known about what effect reducing, removing or bypassing the stomach has on health long term.

But endocrinologists from Sydney’s Garvan Institute have completed the first comprehensive review of the impact of bariatric surgery on bone density and say even the least invasive of the weight-loss procedures may compromise patients’ bone health.

That was a potential repercussion never brought up when Mrs Hall, 30, underwent her gastric-sleeve procedure late last year. She weighed 109 kilograms.

”I didn’t have a bone scan or anything like that,” she said. ”But I do worry I am not getting my recommended daily intake of certain nutrients and I think that’s why they stress the importance of taking a multivitamin after surgery. You do lose a lot of hair in the first three months afterwards, you feel fatigued, and your diet is pretty much clear liquids.”

Now 84 kilograms, Mrs Hall does not regret the surgery, which, she says, has given her more energy, improved her relationship with her family and boosted her self-esteem.

Malgorzata Brzozowska, the endocrinologist who led the review published last week in the International Journal of Obesity, said the more radical the weight-loss procedure, the greater the impact it seemed to have on bones. ”What’s new about this review is that these procedures may cause changes in hormones, which has a negative impact on bones. However, we only have evidence of that from animal studies. So, more research is needed,” she said.

Bone loss was also likely to occur after surgery because fewer nutrients, such as vitamin D and calcium, were being absorbed, while doctors too often assumed that overweight and obese people had strong bones to begin with. ”We are finding that obesity does in fact have a detrimental effect on bone health,” she said.

Dr Brzozowska said bariatric surgery was beneficial to many patients and extremely effective where other treatments failed. ”But the message to convey is people having any of these procedures should take bone health into consideration.”
