Commentary states: The *Neijing* mentions that when heat from the Large Intestine transfers to the Stomach, it leads to excessive hunger and emaciation, a condition termed "Shi Yi" (Gluttonous Emaciation). When heat from the Stomach transfers to the Gallbladder, it is also called "Shi Yi". The Stomach is the sea of water and grain, responsible for transforming food into Ying (Nutritive Qi) and Wei (Defensive Qi). If Stomach Qi is harmonious, dietary intake is regulated, blood and Qi are abundant, and skin and muscles are plump. However, if the Stomach is invaded by pathogenic heat, it consumes the Qi of grain without transforming it into essence and blood, resulting in excessive appetite yet emaciation. This disease is named "Shi Yi", implying that although one can eat, it feels like constant hunger due to rapid consumption or poor absorption. When heat from the Stomach transfers to the Gallbladder, it is also called "Shi Yi", because the Gallbladder belongs to Yang Wood; when heat invades it, it scorches Earth (Spleen/Stomach), accelerating digestion and consuming grains.
