The Effect of Gastric Bypass Surgery on Gut Hormones Related to Bone Remodeling and Intestinal Growth.
The overall purpose is to explore the link between the gut and the bones by investigating
 meal stimulated changes in the blood level of a number of hormones and markers related to
 intestinal growth and bone turnover in patients undergoing surgery for obesity (gastric
 bypass). The hormones will be measured in blood samples taken before and after surgery. The
 results are compared with changes in body weight and body composition as measured by DEXA
 scanning.
