To compare post-operative gut hormones and adipokines by glucagon test in T2DM patients who underwent either RYGB or SG
Intravenous glucagon inhibited plasma des-acyl ghrelin, nesfatin-1 and resistin in T2DM patients 1 year after RYGB and SG.
Post-glucagon suppression of plasma obestatin and resistin was shown in the remitters but not in the non-remitters.
The glucagon test did not affect intestinal hormones at 1 year after either RYGB or SG.
