BPD results in significant weight loss. However, 1 in 4 patients are hypocalcemic, and 1 in 2 have a low vitamin D, despite multivitamin supplementation. BPD patients require routine calcium and vitamin D supplementation for life. Long-term sequelae from these abnormal serum levels are not known.

DS does not improve weight loss or lessen the gastrointestinal or nutritional side effects of BPD.

BPD results in significantly greater weight loss than LAGB in superobese patients, but is associated with a longer hospital stay and a higher complication rate in patients undergoing open BPD.
