People who have had bariatric weight-loss surgery are at high risk of breaking bones. In a recent study presented by The Endrocine Society, an analysis of 258 patients showed that those who had bariatric bypass surgery had 2.3 times the chance of fractures compared with the general population. The likelihood of breaking a foot or hand was especially high-about three times that of the general population. Seventy-nine patients who underwent bariatric surgery between 1985 and 2004 had 132 fractures during a nine-year follow-up. After evaluating various fracture risk factors, researchers found that patients who were more physically active before surgery had a lower fracture risk than those who were less active.
