Weight loss surgery may be associated with bone loss and deficiencies in calcium and vitamin D, suggests a new research.
Weight loss surgery may be associated with bone loss and deficiencies in calcium and vitamin D, suggests a new research.
The study has been accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology and Metabolism (JCEM).With the growing epidemic of obesity, many people are opting for surgical procedures to help promote weight loss. While these procedures result in significant and sustained weight loss and reverse many of the complications of obesity, the new study shows there may be harmful effects on calcium and bone metabolism.
"Our research shows that deficiencies of calcium and vitamin D absorption occur following gastric bypass surgery," said Dr. Shonni J. Silverberg, professor of medicine at Columbia University College of Physicians and Surgeons in New York, N.Y., and coauthor of the study.
"When analyzing hip bone density, we found that those who lost the most weight also lost the most bone," the expert said.
Body Mass Index
The BMI calculator helps you assess your weight indicating if it is normal or if you are underweight or overweight, based on your height.

Researchers also measured bone mineral density before and after surgery using dual-energy x-ray absorptiometry (DXA). One year after weight loss surgery, patients had lost an average of 99 pounds and had significant declines in hip bone mineral density (both total hip and femoral neck measurements).
