Purpose:

This project will study the effects of surgery for obesity on bone metabolism and hormones that regulate appetite.


Study summary:

Subjects will be recruited from the outpatient obesity and surgical clinics at Columbia-Presbyterian Medical Center after they have chosen to undergo a surgical procedure. The groups will not be randomized. Rather, they will decide on their choice of surgery along with their physicians. The patients will be evaluated pre-operatively and followed post-operatively for 5 years. Initial evaluation will include a complete history and physical examination, measurement of calcium, parathyroid hormone (PTH) and vitamin D, and assessment of skeletal health using markers of bone turnover and bone mineral density.
