Comparative effects of gastric bypass and sleeve gastrectomy on plasma osteopontin concentrations in humans.

Roux-en-Y gastric bypass increased circulating osteopontin levels, while they remained unaltered after sleeve gastrectomy.

The increase in osteopontin levels after Roux-en-Y gastric bypass could be related to the increased bone resorption in relation to its well-known effects on bone of this malabsorptive procedure in comparison to the merely restrictive sleeve gastrectomy.
