Our observations are consistent with reported increases in superior mesenteric artery blood flow after GLP‐2 administration in healthy humans, individuals with short bowel syndrome, calves, and piglets (Bremholm et al., 2009, 2011; Guan et al., 2003; Høyerup et al., 2013; Taylor‐Edwards et al., 2011). This evidence concerns the gene GCG and short bowel syndrome.
