Hypotension of the lower esophageal sphincter	Braghetto et al. [48]
Blunting of the angle of His	Himpens et al. [49]
Decreased gastric compliance and volume (leading to increased gastric pressure)	yehoshua et al. [50]
Decreased gastric emptying	Himpens et al. [49], Melissas et al. [32]
Decreased plasma ghrelin (dysmotility)	Nahata et al. [51]
Gastric sleeve shape	Lazoura et al. [52]
Increase in hiatal hernia	Baumann et al. [53]
