Exploring the pathogenesis of pediatric functional dyspepsia based on the theory of"spleen deficiency as the root"
Functional dyspepsia(FD)is a common chronic gastrointestinal disorder in children,characterized by symptoms such as upper abdominal discomfort,abdominal distension,poor appetite,and acid regurgitation.The pathogenesis of FD is complex,involving multiple factors such as gastrointestinal motility disorders,visceral hypersensitivity,and brain-gut axis dysfunction.In traditional Chinese medicine(TCM),it is believed that the theory of"spleen deficiency as the root"is the core pathological mechanism.Specifically,spleen deficiency impairs the normal flow of qi,leading to the accumulation of dampness and stagnation,which brings about gastrointestinal motility issues and visceral hypersensitivity.Furthermore,spleen dysfunction weakens qi and hinders digestive absorption and blood production,worsening gut microbiota imbalances and disrupting brain-gut axis regulation.The TCM treatment strategy for FD involves four key approaches:strengthening the spleen,regulating spleen qi,activating spleen function,and balancing qi flow.Strengthening the spleen and eliminating dampness enhances gastrointestinal motility and removes stagnation.Regulating spleen qi improves digestion and relieves food retention.Activating spleen function restores healthy digestion and absorption.Balancing qi flow ensures smooth coordination of qi ascending and descending to relieve stagnation.These TCM methods align closely with modern medical strategies of regulating gastrointestinal motility,reducing visceral hypersensitivity,and balancing brain-gut axis.This study systematically explores the pathogenesis of FD and the treatment strategy of integrating TCM with modern medicine from the perspective of"spleen deficiency as the root".It highlights the intricate interactions among spleen function,the brain-gut axis,and gut microbiota.This research provides theoretical foundation and guidance for the treatment of children with FD.
