Abstract: In the treatment of diabetic gastroparesis (DGP), traditional Chinese medicine has conventionally focused on therapies such as ascending clear and descending turbid, pungent-opening and bitter-descending methods, aiming to regulate the ascending and descending of the spleen and stomach's Qi mechanism and to restore the middle-jiao's transformation as the ultimate goal. By exploring the physiological relationship between gallbladder and spleen-stomach and its pathological relationship with DGP, this article suggests that the gallbladder also participates in the regulation of blood sugar and digestive activities in the body, which is closely related to the onset of the disease. As the Shao Yang pivot, the gallbladder stores essential fluid, harbors ministerial fire, primarily governs the upward movement and dispersion, and is responsible for decision-making and emotions. The normal flow of Qi, blood, and body fluids, as well as the functional activities of the channels and collateral vessels, are closely associated with the gallbladder. When the gallbladder's function becomes abnormal, the body may also exhibit imbalances in the intestinal microbiota, disarray of gastrointestinal hormones, delayed gastric emptying, and elevated blood sugar levels, which aligns with the modern medical understanding of the onset of gastroparesis diabeticorum. Therefore, this article proposes the treatment principle of "venting the wood constraint" and the treatment of DGP according to symptoms, offering a reference for clinical treatment.
