Reduction of stomach volume

The concept "caloric intake restriction via reduced stomach volume" refers to a **physiological or surgical approach** rather than a discrete molecular target. It is most commonly achieved through **bariatric procedures** such as sleeve gastrectomy or adjustable gastric banding. These interventions physically reduce the size of the stomach, thereby limiting its reservoir capacity for food and promoting early satiety. This mechanical restriction is often accompanied by changes in gastrointestinal hormone secretion—such as increased levels of satiety hormones like GLP‑1 and PYY and decreased levels of hunger hormones like ghrelin—which further contribute to reduced appetite and improved metabolic outcomes[2][3][4]. While some drugs can mimic aspects of this effect by slowing gastric emptying or modulating gut hormones (e.g., liraglutide), there is no single molecule or receptor that directly corresponds to "caloric intake restriction via reduced stomach volume." Therefore, this entry does not represent a canonical molecular therapeutic target but rather describes a physiological mechanism leveraged in obesity treatment. **Note:** This entry is not a specific molecule/receptor but describes an anatomical/physiological intervention; thus it should be flagged as incorrect for structured molecular target databases[2][3].
