The physiology of gastric emptying (GE) is complex and incompletely understood due to the interplay of several factors such as age, sex, volume, pH, temperature, osmolality, ion and energy content, gravity, posture, physical activity, and food consistency [1, 2, 3, 4, 5, 6]. It is well known that posture and gravity affect GE mainly via changes in gastric configuration, which changes the intra-gastric distribution and ultimately the pressure gradient (pressure pump mechanism of GE) across the gastroduodenal segment [7]. Postural changes are also associated with changes in gastric motility (peristaltic pump mechanism of GE) and intra-gastric distribution of liquid meals [7, 8].

The pattern of GE is known to vary among individuals, but remain consistent within individuals [ 9]. The post-gastrografin pictures of the author (V.A.) (Fig.  1) illustrate the actual changes in gastric configuration accomplished by the sequential posture changes (SPC) described in the present study. The SPC...
