Gastric volume (None established; "GV" is not a widely recognized abbreviation in the scientific literature.)

Gastric volume refers to the total physical capacity of the stomach at any given time. It plays an important role in regulating short-term food intake by providing mechanical feedback through distension—the stretching of the stomach wall—which signals satiety and inhibits further eating independent from nutrient content[5]. In clinical practice and research on obesity treatment, various surgical devices are used specifically to restrict this anatomical space ("gastric restriction"), thereby promoting weight loss primarily through limiting meal size and enhancing feelings of fullness after smaller meals. However, while changes in hormones such as ghrelin have been observed following these interventions, current evidence suggests that mechanical limitation rather than hormonal changes is primarily responsible for their efficacy; other factors like gut motility and neural responses also contribute but are less well understood[3]. Gastric volume itself should be considered an anatomical/functional property rather than a discrete druggable biological target.

Stomach volumeGastric capacity

For interventions that manipulate gastric volume: Mechanical restriction—devices reduce stomach capacity to limit food intake and promote early satiety. Indirect modulation—changes in hormone secretion (ghrelin, gut peptides), neural signaling due to altered distension.
