Abstract: Functional dyspepsia (FD) is a common gastrointestinal disorder in pediatrics,closely associated with poor diet and lifestyle habits.The main clinical manifestations include upper abdominal fullness,pain,anorexia,belching,nausea,vomiting,and acid regurgitation.If not intervened in time,this disease may lead to growth retardation and malnutrition.In western medicine, this disease is often managed by symptomatic therapy,such as using prokinetic and antisecretory drugs to improve children's appetite and relieve abdominal distension and abdominal pain,but it is easy to recur.Numerous studies have proved that traditional Chinese medicine (TCM) is safe and effective in improving anorexia,belching,abdominal distension,abdominal pain,vomiting,etc.,and can be used alone to treat children with FD.Prof.Xiong Lei,a representative figure of the Diannan School of Pediatrics,believes that the origin of this disease is always in the spleen and stomach:it may be because "yang is exposed to wind" and the pathogenic qi invades the stomach,blocking the flow of qi in the middle jiao,or it may be because "yin is exposed to dampness" and the dampness is trapped in the spleen,resulting in the dysfunction of spleen,which leads to FD.Based on the theory of "yang is exposed to wind and yin is exposed to dampness",prof.Xiong believes that when the spleen and stomach are trapped,non-aromatic TCM cannot activate them.In clinical practice,the use of TCM formulas with aromatic characteristics can activate the spleen and eliminate dampness,regulate qi of the middle jiao,and restore the function of the spleen and stomach,thereby having significant therapeutic effects in the treatment of FD.
