Abstract: Functional dyspepsia (FD) is a common digestive disorder among children. Clinically, it is primarily characterized by postprandial fullness, early satiety, upper abdominal pain, or a burning sensation in the upper abdomen. It may also be accompanied by symptoms such as belching, acid regurgitation, nausea, vomiting, poor appetite, and abdominal distension, presenting a wide range of manifestations. FD is prone to recurrence and has a relatively prolonged course. According to its main symptoms, it is categorized into conditions such as "abdominal pain," "abdominal distension," "epigastric fullness," and "vomiting" for syndrome differentiation and treatment in traditional Chinese medicine (TCM). The etiology of FD is often attributed to improper diet or post-illness disorders, with the pathogenesis being dysfunction in the ascending and descending mechanisms of the spleen and stomach qi. In Huang's Pediatric School of central Guizhou Province, it is believed that whether it is deficiency or excess, "the failure of the spleen to transport and regulate" is the key to the pathogenesis of pediatric FD, and it is also the core pathogenesis of the symptoms such as "epigastric fullness, distension, and pain." In clinical practice, the severity of symptoms, duration of the disease, and characteristics of the nasal root and eyelids are assessed to determine the nature of the syndrome, including cold, heat, deficiency, and excess. Thus, the "Spleen regulation and mediation method" is established, and the "Spleen-regulating and Fullness-relieving powder" is used for syndrome-differentiated treatment, aiming to rapidly restore the "spleen-transporting" function in children with FD and achieve the state of the spleen "regulating the qi of the four viscera," which provides a clinical reference for TCM treatment of pediatric FD.
