Bariatric Surgery Doesn’t Hike Fracture Risk

Friday, 17 Aug 2012 02:41 PM


Obese patients who undergo bariatric surgery to lose weight are not at any greater risk of broken bones in the first few years after the operation, but may be prone to fractures later, new research shows.
The international study, led by researchers at the Medical Research Council Lifecourse Epidemiology Unit at the University of Southampton, compared the fracture rates of people who had had bariatric surgery between 1987 and 2010, with those who had not had the surgery but were matched by age, sex, weight and other factors.
Results showed the overall risk of bone breaks was not significantly increased in bariatric surgery patients in the first few years after the procedure, but there was a slightly increased fracture risk after three to five years. This was particularly true for people who had a greater decrease in weight, according to the study, published in the British Medical Journal.

Researchers noted that a higher Body Mass Index (BMI) protects the bone against most types of fracture. A higher BMI is associated with increased bone density and offers more protection around the bones.
Studies have shown that weight loss can lead to a reduction of bone density, but the new research indicated it doesn’t raise a person’s immediate fracture risk.
Bariatric surgery is used to treat people with obesity who do not respond to non-surgical treatments. It includes gastric bypass or gastric band.
"Obesity is an increasing public health problem worldwide [and] it has been recognized that surgical treatment is the most effective route to weight loss for many with morbid obesity,” said Dr. Nicholas Harvey. “Overall, for the first few post-operative years, these results are reassuring for patients undergoing bariatric surgery, but do not exclude a more protracted adverse influence on skeletal health."
